Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPI3B+)

Sakaki, can RDP (Remote Desktop Protocol) be run on the Pi?
I don't have a Windows10 box but I seem to remember running RDP on a Pi and Windows 7 has native RDP support so no VNC software was needed.
I sometimes have issues with VNC on Windows.

Re: 64-bit operating system

I run Gentoo64, it does seem faster and better than previous Raspbian. Have not tested against just released spin, today is first day on new release. But I don't expect much improvement as the SDRAM is still only 32bit wide. To get max use of AARCH64 code would need to be optimized too? Those that s...

Re: 3A+ usbboot/rpiboot

I love the USB boot mode on Zero's, it's become the major way I develop VC4 code. It saves so much sd card wear. Obviously the standard USB A type connector does not have the ID pin. If it did boot as a device would 100-500ma be enough for 4 cores? So it would need to be powered via the normal metho...

Re: Operating Systems:

I made one of these from a kit, but used cmos chips and cpu not TTL logic, ran much cooler.
Big step up from the Z80 Microbee, it had an OS, eventually ;)

It was our local version of the Amiga.
And people complain about the 3A+ only having 512MB ;)

Re: Speedometer for cars using Pi

Thanks for the reference of this new library but I want to use a low level library. It's easier to maintain the code. That's why I use Ultibo ;) The only lower level is assembly :lol: Source code is only a few 100k for my bigger apps. Most of that is reusable libraries with the main application onl...

Re: Pi 3 A+ !!

whatever we do next will of necessity be less of an evolution
So next one will be revolutionary?
Less of an evolution is Devolution?

Anyway, time to practice coding tighter.
Mobil robots with CV?

I guess this means full steam ahead with Pi4, perhaps roadmap for 5, 6 ?

Re: Divide By Depth??

One example is OpenGFX430, this is a 2D GPU, though it works and is a big step in the correct direction. Their is another example, though I do not think it is likely to be very usable for the purpose of a SoC or computer. The best one that I know of is ORSoC Graphic Accelerator, that has some real ...

Re: Speedometer for cars using Pi

Raspban and Pygame was my first method 6 yrs ago but it was not that fast and it was buggy, mainly reading the i2c sensors. I had been using JavaFX for dash type displays on my old stuff. At the time JavaFx was accelerated but it really needed Pi2-3's to get fast enough. Development was done with Ne...

Re: Am I in the right place?

You are the same age as me when I started on Pi's ;) But as ejolson says get a smart phone or MP3 player if that's all you want to do. That way you can listen to music while trying to figure out Linux on Pi's :D Messing about with Pi's means you soak up Linux knowledge. Pretty soon you grab a copy o...

Re: Making a Gaming mouse?

Maybe, but what about booting it? It may take a minute before you can even use the mouse.
2-3 seconds on Ultibo, less interference from Linux OS :D

Hmm use a Zero as a Mouse, another Zero as Keyboard?
Or try a Microbit? Arduino?

Re: Making a Gaming mouse?

Disregarding how you would achieve it, the Pi is not "real time" enough for this use But would it be? Mice use USB, there is some time used up there. A mouse would have sensor(SPI) to USB interface micro. Would direct SPI be faster? With Pi's we can test this, thanks to the IO header. https://on-wi...

Pair amber with some very simple periphials, and one of the Open source GPU's, implement the ASIC, slap a good PMMU in the system, and put it on a board with 3GB of DDR RAM and that would be the perfect next gen Raspberry Pi, especially if the ASIC had 8 of these Amber Cores (and the associated PMM...

The phrase "Must have 64bit for learning" is nonsense. Saying "32 bits is OK for kids" shows a massive misunderstanding and is just a bit insulting to children and adults alike.
