My es2gears went black

Es2gears is like glxgears except for OpenGL ES instead of OpenGL. It used to work, apparently something I installed broke it.

It's running and doing benchmarks but with a black window. And why is it EGL_VERSION 1.4? I don't remember what that used to say but I thought the pI used EGL 2.1 max. Omxplayer still works normally. I was doing some fiddling with GLFW, I'm just starting to try to learn OpenGL. But I'm interested in Broadcom's OpenGL ES implementation. Hello_teapot and hello_triangle still work.

Last night I updated my Broadcom userland by doing a git pull from https://github.com/raspberrypi/userland es2gears is the first broken thing I've seen. I wonder if the blank window has to do with no shader info showing? I'm not sure how long it's been broken.

EGL 1.4 is correct, the very latest version is only 1.5 so no chance of you seeing 2.1.

OK, thanks. I thought the version was dependent on firmware, but then again somebody would have to write the firmware. And Broadcom would probably not find it profitable to invest time doing that.

I was looking a little at GLFW yesterday and a guy at http://discourse.glfw.org/t/glfw-on-rpi ... pengl/1215 claims 2.1. But maybe it's not using the Broadcom hardware version. I'm not sure what the stuff he has on Github actually does, I didn't try it, don't know how to. I'm not interested in software OpenGL, that's been around 20 years or so. I want to utilize the GPU hardware.

I dug up source for es2gears at https://raw.githubusercontent.com/ehsan ... es2gears.c and made a simple makefile:

Code: Select all

CC = gcc
es2g:es2g.c
        $(CC) -o es2g es2g.c -I/opt/vc/include -L/opt/vc/lib -lm

But it seems to need GLUT and a bunch of other stuff. I was trying to not use anything that isn't in /opt/vc. Still they're only undefined references meaning libraries not found (I think).

I see 3 "server glx version string:" lines in there, that may be a problem.

OK, thanks. I thought the version was dependent on firmware, but then again somebody would have to write the firmware. And Broadcom would probably not find it profitable to invest time doing that.

I was looking a little at GLFW yesterday and a guy at http://discourse.glfw.org/t/glfw-on-rpi ... pengl/1215 claims 2.1. But maybe it's not using the Broadcom hardware version. I'm not sure what the stuff he has on Github actually does, I didn't try it, don't know how to. I'm not interested in software OpenGL, that's been around 20 years or so. I want to utilize the GPU hardware.

I think you were confusing EGL with OpenGL. EGL is a library that connects the rendering libraries (OpenGL, OpenGL|ES, OpenVG) to the underlying display libraries (X, framebuffer, DispmanX etc.).

The Broadcom libraries are EGL 1.4 and OpenGL|ES 2.0. To use OpenGL 2.1 would need the MESA drivers (or a shim), Eric Anholt's drivers are MESA based and use the RPi's hardware as much as possible, I think it is OpenGL 2.1 but with a few features missing due to the hardware not supporting them.

I never said I knew what I was doing, I'm just trying to learn. But I'm only interested in the fast hardware stuff. I thought EGL was an abbreviation for OpenGL ES.

If I turn on the GL driver in raspi-confg my es2gears isn't black anymore. But that seems to slow everything down so I usually leave it off. The Broadcom stuff in /opt/vc doesn't need it, or even X, omxplayer either. And with it on my hacked es2gears gives me

Code: Select all

libGL error: MESA-LOADER: failed to retrieve device information
MESA-LOADER: failed to retrieve device information
MESA-LOADER: failed to retrieve device information
* failed to add service - already in use?

But it wasn't working anyway really, I don't need it.

If I knew how to get a framebuffer window from GTK I probably wouldn't bother with any of this. I just want to be able to plot points really fast with minimal CPU involvement, I thought using vertex shaders and passing them off to the GPU would do the trick. I was using XDrawLines from xlib with partial succcess, doing XOR draws and erases. Stacking the array of lines so the even ones were erase lines and the odd ones were draw, then next batch swapping the odd lines into even positions and putting new odd ones in. Faster than it sounds, and runs about 4% CPU. But no widgets yet.

Raspbian by that mesa 13.0.6 number.

If you just want to plot lines OpenVG is simpler.
Not much different than the old HPGL plotter language.
Lift pen, goto x,y, lower pen, draw to x1,y1 etc

AJ has proabably done the most useful and easy to understand code
https://github.com/ajstarks/openvg

EGL is a layer under OpenVG and OpenGLES.
Erics OpenGL is a layer above OpenGLES sort of.

It is all a pretty steep learning curve

Many, many books to read, most don't make sense the first two or three times

OpenGL can be done on any PC, that's why I use Gentoo64, the OpenGL on that is better than Raspbian.
I'm Learning OpenGL first, then going port that down to the subset of OpenGLES, er once I understand that

With the PC/Gentoo64 combo I can use and play with examples in many langauges, not just C.

The best OpenGL examples are the Mesa3D ones, normally a single C file is all you need to understand.
As you just discovered debugging mistakes is not easy, I'm still learning that.
Use apitrace?

OpenVG may be simpler but does it have shaders? Being able to launch a shader and have it run independently of the CPU is really appealing. I could put my data into an array and have the shader plot it (I think) while I'm calculating the next batch. But accelerated X drivers aren't bad.

There's Xlib's XDrawLine and the batch version XDrawLines. I was playing with it in just Xlib which has no widgets for things like buttons. But to some degree every widget is a window so I think I can do that in GTK on any surface. I've been puttering around writing a couple LXDE plugins lately so I gained a little confidence in experimenting with GTK. You don't have access to all of GTK doing that but hopefully enough to practice. Glade is a good tool, but it also helps you see how to do without it. This is done using Cairo, I'll probably skip that.

OpenVG uses a control list, page 72 on the VC4 manual.
Page 68 code 41/42 "only for use with VG shader mode"
When you use 3D then it is a vertex list and texture mapping.
Page 69 code 66, 67 VG Shader State and VG Inline Shader Record.

These are the few pages I nearly understand

I am not to sure how fast OpenVG can be pushed.
I did a mockup LCARS GUI, clock and HUD and never noticed flicker etc.
Is there benchmarks for OpenVG? Google time

It all sounds way more complicated than just using a framebuffer. If you want to make an image height * width (* 3 colors) you allocate (malloc or calloc) height * width * 3 bytes. If you want to turn on a pixel in there at x,y you write to offset (y * width) + x. Colors are in sequence (rgb) along each line so the green part of the pixel at x,y would be at x+1,y (or (y * height) + x + 1). You can move/copy something with memmove. The same principles work for a framebuffer as for creating a png, jpeg, gif, tiff file, only then you call a library function (pnglib, jpeglib, etc.) to write out your memory buffer in the image format you want. Height * width * 3 is pretty standard for 24 bit color, they all work the same way. VNC (AKA remote framebuffer) works like that only it's meant for sending to another computer so then you have to run a client to see it. And I haven't found a way to have just a framebuffer in a window. If the display were memory mapped there'd be a big jump in address between the right side of the window and the left side of the next line up, but you could deal with that. It would be constant as long as you didn't move or resize the window, then you'd need to recalculate.

OpenGL is intended for completely different purposes than what I have in mind. I'm only interested in it as a standardized way of utilizing the power of the GPU. I could write for Videocore or for Mali but code for one wouldn't work on the other. Unless I do it as OpenGL which is implemented on both.

This is from VNC, done July 2017. I get a radio input from an RTL2832 dongle using librtlsdr, put it through some calculations including FFT. Each signal above the noise threshold becomes a peak in the top (white) trace. Those come and go very fast, ideally 4 - 20 frames/second. At the bottom is the waterfall. Every line (starting at the top) has a color that reflects the intensity of the peak that was just displayed at the top. So the bottom of the display needs to move down 1 pixel 4 - 20 times per second. There was a bug here causing the bands at the bottom to not line up with the peaks at the top, but the waterfall is a history of the peaks displayed. If you use a working one like Sdrsharp or Hdsdr you tune in a signal by clicking on it. Then that part gets demodulated and you hear audio. But there's nothing that does this well on a Pi, most programs are for Windows or big computers so they aren't very efficient (like Gqrx). I'm trying to streamline the process and optimize it for small computers. Doing graphics with just Xlib makes it very portable. A framebuffer could be too. And a framebuffer is just moving bytes around in memory so it's fast and efficient. A framebuffer is what OpenGL outputs into, I just want to skip the over OpenGL.

Googling turned up this old thread https://www.opengl.org/discussion_board ... ramebuffer Yes, OpenGL "protects" me by not letting me write to memory wherever I want. But come on, I'm a C programmer x20 years, once in a while I make a booboo and get a segfault or something strange on the screen, but not often. And X subscribes to the same philosophy, so only things like qt and OpenGL can get pointers they're allowed to write to. And probably only 1 person in 1000 wants to do it anyway.

That was an oversimplification above, let int stride = # of bytes/pixel, ie 3. Then offset(x,y) = (y * stride * width) + (x * stride). r,g,b is + 0,1,2 on top of that.

DRI is maybe what I want, if I can access it https://en.m.wikipedia.org/wiki/Direct_ ... astructure I just tried driconf, which tells me Screen "0" is not direct rendering capable. It's mostly i386 stuff.

ab1jx · Thu Jan 31, 2019 9:24 pm

The key is probably in there, but it's not likely to be portable to anything else. Unless I go up to something standard like OpenGL ES so it goes through OpenGL ES implementations on other machines.

There was this project https://github.com/elorimer/rpi-playground But there was one which had several articles, one of which had a way to get a framebuffer. This: https://rpiplayground.wordpress.com/201 ... ofit-pt-1/ They open() it like a file, it was very slow. I don't know if you could mmap it or not. May be the same article but I think there's a way to request a framebuffer from the GPU by sending a message to its mailbox. /opt/vc/bin/vcmailbox sort of message. Again not portable but a framebuffer mostly is I think once you get it.

Deprecated? Rats. https://github.com/raspberrypi/firmware ... -interface

I'll see if this still works https://elinux.org/RPi_Framebuffer

The rpiplayground hello world from 2014 just crashed on me, maybe because it's written for a model A or B Pi and I'm on a 3B. Maybe I was on my Model B when I first tried it. Display or mouse cursor at least locked up.

Two Norweigian papers have been useful
https://core.ac.uk/download/pdf/30863461.pdf
https://core.ac.uk/reader/30863509

A nice explanation of how Tile Engines work too.
That's been a mystery for me till now.

Most of the baremetal guys have got framebuffer working, even double buffering?
Been done in asembly, C, C++, Rust and Free Pascal so far, perhaps more?

I want to do spectrogram displays on baremetal, not much difference than waterfall.
I have even started looking at FPGAs to do the FFT's in hardware, I expect it will take me a few years to learn that

FFT's can be done in the QPU's but what happens to them if I use OpenVG to then plot the data?
Not sure how to measure QPU usage, so I am looking at ARM's Compute Library to run the FFT in the Quad ARM CPUs/NEON.

I think I saw one of the SDR guys looking at FPGA's too.
Only a few years ago this equipment cost S10,000-$100,000.

ab1jx · Fri Feb 01, 2019 5:39 pm

Spectrogram, have you looked at rtl_power?

Code: Select all

rtl_power, a simple FFT logger for RTL2832 based DVB-T receivers

Use:    rtl_power -f freq_range [-options] [filename]
        -f lower:upper:bin_size [Hz]
         (bin size is a maximum, smaller more convenient bins
          will be used.  valid range 1Hz - 2.8MHz)
        [-i integration_interval (default: 10 seconds)]
         (buggy if a full sweep takes longer than the interval)
        [-1 enables single-shot mode (default: off)]
        [-e exit_timer (default: off/0)]
        [-d device_index (default: 0)]
        [-g tuner_gain (default: automatic)]
        [-p ppm_error (default: 0)]
        [-T enable bias-T on GPIO PIN 0 (works for rtl-sdr.com v3 dongles)]
        filename (a '-' dumps samples to stdout)
         (omitting the filename also uses stdout)Experimental options:
        [-w window (default: rectangle)]
         (hamming, blackman, blackman-harris, hann-poisson, bartlett, youssef)
        [-c crop_percent (default: 0%, recommended: 20%-50%)]
         (discards data at the edges, 100% discards everything)
         (has no effect for bins larger than 1MHz)
        [-F fir_size (default: disabled)]
         (enables low-leakage downsample filter,
          fir_size can be 0 or 9.  0 has bad roll off,
          try with '-c 50%')
        [-P enables peak hold (default: off)]
        [-D enable direct sampling (default: off)]
        [-O enable offset tuning (default: off)]

CSV FFT output columns:
        date, time, Hz low, Hz high, Hz step, samples, dbm, dbm, ...

         Examples:
        rtl_power -f 88M:108M:125k fm_stations.csv
         (creates 160 bins across the FM band,
          individual stations should be visible)
        rtl_power -f 100M:1G:1M -i 5m -1 survey.csv
         (a five minute low res scan of nearly everything)
        rtl_power -f ... -i 15m -1 log.csv
         (integrate for 15 minutes and exit afterwards)
        rtl_power -f ... -e 1h | gzip > log.csv.gz
         (collect data for one hour and compress it on the fly)

Convert CSV to a waterfall graphic with:
         http://kmkeen.com/tmp/heatmap.py.txt

I don't really like the heatmap.py that comes with it so I created my own. This is done from the csv file that rtl_power outputs. I pirated the font from an old giflib. The palette converting signal intensity to color came from one of Learmonth's gifs http://www.bom.gov.au/metadata/catalogu ... 0483.shtml But same technique as writing to a framebuffer, I was just using jpjeglib to make jpeg files intead. I had to reduce the size or the RPI board said it was too big. You can see my dongle being flaky at the top above about 1200 MHz. This is from 2016.

From 2012. Done by changing frequencies on an Icom radio (maybe). I came late to $10 SDR dongles. I have an IC-7000(?) and did a bunch with Hamlib, but it's not exactly fast.

This (and libjpeg) is all it takes to turn my memory array into a jpeg. That array could be a framebuffer. My array is actually 8 bits/pixel using a palette ("colors[]") so I'm outputting the rgb values from the palette, indexed by the value stored n the array to get 24 bits. This was pre turbo-jpeg I think, looks a little different. Made from one of the demo programs that comes with the library.

Code: Select all

void make_jpeg(void) { // sends img array to compression
  struct jpeg_compress_struct cinfo;
  struct jpeg_error_mgr jerr;
  JSAMPROW row_pointer[1];
  int i,j,ival;
  jline = malloc(3000 * sizeof(unsigned char));
  if (jline == NULL) {
    printf("Error getting 3k of RAM for a jline.\n");
    exit(1);
  }
  cinfo.err = jpeg_std_error(&jerr);
  jpeg_create_compress(&cinfo);
  opf = fopen(jpegname,"wb");
  if (opf == NULL) {
    printf("Error creating %s.\n",jpegname);
    perror("jpeg ");
    exit(1);
  }
  jpeg_stdio_dest(&cinfo, opf);
  cinfo.image_width = width;
  cinfo.image_height = height;
  cinfo.input_components = 3;
  cinfo.in_color_space = JCS_RGB;
  jpeg_set_defaults(&cinfo);
  jpeg_start_compress(&cinfo, TRUE);
  i = 0;
  while (cinfo.next_scanline < cinfo.image_height) {
    for (j=0; j<width; j++) {
      ival = img[(i*width)+j]; // 8 bit image value
      jline[(j*3)] = colors[ival].Red;
      jline[(j*3)+1] = colors[ival].Green;
      jline[(j*3)+2] = colors[ival].Blue;
    }
    row_pointer[0] = jline;
    (void) jpeg_write_scanlines(&cinfo, row_pointer, 1);
    i++;
  }
  jpeg_finish_compress(&cinfo);
  fclose(opf);
  free(jline);
} // make_jpeg

Essentially I made my own graphics library

Code: Select all

 
 void tick(int x, int y) { // draw a simple +
  int xt, yt;
  for (xt=x-2; xt<(x+3); xt++) { // horizontal part
    if ((xt > 0) && (xt < width)) {
      img[(width * y) + xt] = tickval;
    }
  }
  for (yt=y-2; yt<(y+3); yt++) {
    if ((yt>0) && (yt<height)) {
      img[(width*yt) + x] = tickval;
    }
  }
}

But it's that same img[(width * y) + xt] algorithm that turns a 1-dimensional array into a 2-dimensional image.

Maybe, but you can't buy one in the US because it doesn't do ATSC so it won't work. It does DVB-T or something like that, only useful in Europe. Our TV isn't worth bothering with anyway. Not marketed here. I have an ATI HD-750 "TV Wonder" USB dongle that was a total waste of $20 or so. Can't find any drivers for it, Windows or Linux, never had it working. I have a Happauge (I think) card that plugs into a PCI slot (circa 2002) that does work, might be able to do SDR. Never got the DVB working on the rtl2832 dongles either.

I got a cheap rtl2832 for under $11 from Banggood or someplace like that, supposedly it's not quite as good. It sort of works. I have about 3 NooElec ones that are fine. One runs all the time recording temperatures from an outdoor sensor with rtl_433, I have 2.5 years worth of data from it. Plugged into an old laptop with a good oversize battery so it takes a long power outage to bring it down. A Pi could probably do it.

Been thinking about your plots, so much signal/noise it is basically just pixels.
Framebuffer is the way to go, OpenGLES/VG etc probably won't speed up plotting pixels.
That does mean those QPUs are free to do FFT's.

A Pi can definitely log data, got more than 4 years of proof. PiCore version of TinyCore Linux.

Been a few years since i looked at SDR, things are happening

A FPGA hat that can do SDR too

ab1jx · Sat Feb 02, 2019 2:47 pm

Only £149.99 (inc VAT)
That can wait, that's for sure (Trilby hat)

I don't have a 3B+, just 3 3Bs, don't plan on buying one. I'd be more apt to get a RockPro64 https://www.pine64.org/?page_id=61454 but I'm definitely interested in a 14 inch Pinebook when they're available again. https://www.pine64.org/?page_id=3707 I have a Rock64, not sure why I'm not using it. I got the model with 4 GB of RAM because that seems to be the biggest shortcoming of the Pi. The Pi has a much bigger userbase and it's much more polished. Bleeding edge Rock stuff is all done in Chinese, it takes a while to trickle down to English. There's unstable software for it, I'm running an Ayufan image and I have 58 days of uptime right now. Armbian I didn't like.

But being able to make the WiFi wander is something I thought of a long time ago, even posted a question once about it. I don't have anything that receives 2.4 GHz, other than wifi. I'd put a dish on it and do SETI. Or use a pair of them and do interferometry (radio astronomy).

ab1jx · Sun Feb 03, 2019 2:44 am

Now I'm not sure what to think. I used this code https://stackoverflow.com/questions/195 ... spberry-pi and it not only worked, it seemed very fast. They open /dev/fb0 (standard framebuffer device) as a file, then use mmap() to get a pointer. So very quickly the top half of my screen looked like:

: so_fb_test1.png (25.21 KiB) Viewed 1376 times

Except I guess I was expecting a small area. I've got a pointer that (probably) lets me read and write anywhere on the screen. With no mailboxes or memory barriers or any of that. I think that stuff is being handled by bcm2708_fb.c which is part of the kernel. I guess I can back up the area I want to write to and go ahead and write. Freaky.

Exactly, looking in bcm2708.c I see on searching for mailbox:

Code: Select all

       pr_info("bcm2708_fb_set_par info(%p) %dx%d (%dx%d), %d, %d\n", info,
                info->var.xres, info->var.yres, info->var.xres_virtual,
                info->var.yres_virtual, (int)info->screen_size,
                info->var.bits_per_pixel);

        /* ensure last write to fbinfo is visible to GPU */
        wmb();

        /* inform vc about new framebuffer */
        bcm_mailbox_write(MBOX_CHAN_FB, fb->dma);

        /* wait for response */
        bcm_mailbox_read(MBOX_CHAN_FB, &val);

I was thinking I'd like to make a GTK widget that's like a drawing area in a frame with buttons and controls around it. I didn't expect it to take over the desktop. Now how to put a transparent window to the framebuffer in the middle of a GTK app I still have to figure out.

Gavinmc42 · Sun Feb 03, 2019 3:10 am

Easier to take over whole screen.
I think you need to use Dispmanx and EGL to get a Window in x11?
I don't get how to yet.

No 3B+

That's the best one, it just pushes the Pi's over the edge into useful desktop PC territory .
One of mine is an early one, does not like full speed 1.4GHz, but 1.3GHz is fine.

I might get a Mali based SoC but only to play with ARM's compute Library Mali based OpenCL
Pi based OpenCL is not quite there yet. hey I should check that for FFT.
https://github.com/doe300/VC4CL

Because of the DMA-interface which has no MMU between the GPU and the RAM, code executed on the GPU can access any part of the main memory! This means, an OpenCL kernel could be used to read sensitive data or write into kernel memory!

Of course doing fft on the QPU's and allowing the VC4 to write to framebuffer memory is a NICE feature

Not sure if there is FFT in the Compute library?
Yikes, lots in there, going to takes ages to search.

If I had time and money to learn another probably an Allwinner A64 based SoC like this one?
https://www.olimex.com/Products/OLinuXi ... e-hardware
Apart from the Mali GPU the rest is very Pi like,the only reason to get it would be to learn the Mali GPU.

For support datasheet wise iMX8 family.
The 8 core (9 if you count the dsp) 4K, Vulkan is probably going to be Pi4 like?
4K and Vulkan interest me more than Mali.

ab1jx · Sun Feb 03, 2019 4:06 am

There's always /opt/vc/src/hello_pi/hello_fft as an example. Not sure if it's really going to be faster than fftw or not but it's one less thread. Passing stuff back and forth to and from the GPU may be slower than what you gain. Computers are a lot faster than in 8088 days. I have a gphoto project where I'm taking viewfinder images (over USB) from a camera and comparing them to see whether anything changed or not, for a wildlife camera. I put every pixel in those images through several rounds of calculations and i still get about 8 frames/second. On a Zero. Runs for hours on a 12 volt 7 AH SLA battery. False triggers too much, like when a cloud goes over. The last thing I was trying was averaging all the pixels then comparing each one to the average, so a cloud will hopefully affect the average

Thanks for the OpenCL link, I've sort of been watching that. If you can do OpenCL you can mine Bitcoin (or about anything else). Guys build these computers with multiple video cards, draw hundreds of watts. ASIC rigs are more efficient but with OpenCL you can just use different software for different coins/algorithms. Really need to have free electricity like solar to make much profit though. And the more you invest in hardware the faster it goes. There's no free lunch.

Dispmanx, I don't know. If I can read where the corners of the window are in pixels I can calculate addresses to write to in the framebuffer. Doesn't matter what's under it, it will be gone. I could use a drawing area but draw with the framebuffer there instead. I'll need to be able to read mouse clicks, I can do that from GTK I think. But I can't be the first person that's ever wanted to do this, I'm probably reinventing the wheel.

My Zero was analyzing the pictures and tripping the shutter here. I assembled them with Photoprint and the order is weird, it mostly starts at the upper right and ends lower left. No, worse, the 2 of him holding the sausage over the edge of the wall were last. He's watching people in the house about 10 feet away to the right.

I tried 4+ years ago to do motion detection based on jpeg file size difference.
Gave up and used MotionPie, which I still use along with Pikrellcam.
Pikrellcam uses the motion vectors generated by h.264 for motion detection.
Big moving tree branches will trigger but clouds not so much.

Have not made a portable version yet, need to collect a few more Zero's.
Been looking at solar but always on is power hungry, or so I thought.

Hmm, I can't afford to fly to Europe. I have a few dishes, mostly TVRO, but one big old 4 footer I grabbed from the dump andnever used. For all those MHz up there not much of it's very interesting. I happened to hear the state police catching the Boston Bomber a few years back at 900+ MHz.

A real simple way to deal with solar is a PB137 chip mounted on something for a heat sink. https://www.alldatasheet.com/datasheet- ... PB137.html Handles about 1 amp, puts out 13.7 volts, 3- terminal regulator chip like an LM7805. Intended specifically for charging lead-acid batteries. Linear, not switching but less radio noise too. Use one on each 20 watt panel. I have 3 old Harbor Freight 20 watt monocrystalline panels, a 26 watt or so polycrystalline, then last winter I picked up a new 100 watt polycrystalline from Home Depot for $100 with free shipping. None of them hooked up at the moment.

Working on a scroll test program with a framebuffer. No crashes yet but I'm juggling it around things that I don't want interrupted. I can back up a screen area to memory and put it back, now to write the big test.

We're just coming out of a 2nd cold snap of the year, this has a fancy name of polar vortex. Killed 2 dozen people in the midwest, I remember 20 below was fairly common, that was before the polar vortex name but probably the same thing.

I'm using a 1920x1080 screen on a Pi 3B, scrolling 50% of the width in the center of the screen, an area 90% of the screen height high. In about 9 seconds the top scrolls off the bottom. CPU usage, looks like it's keeping 1 core pretty busy, but I'm running it flat out too to see what it will do. I don't need to scroll this fast, more like 10 lines/sec.
