Re: ads7846 on spi1

That's recent enough - it's the last firmware released before the switch to the 4.14 kernel tree.

Start by renaming the compiled overlay to "ads7846-spi1.dtbo" to distinguish it from the original, comment out the current overlay directive in config.txt and replace it with:

Code: Select all

dtoverlay=ads7846-spi1
Verify that the driver module gets loaded. Then add the parameters, leaving out keep_vref_on, and splitting the line when it reaches 80 characters.

its the firmware delivered with the screen, also with the same parameters.
Perhaps the supplier of the screen has modified the standard overlay - can you upload the original .dtbo (or .dtb) somewhere so I can take a look?

No, this was correct - it was the rename I got wrong (now corrected).

The default ads7846 overlay was unmodified, so it had no "keep_vref_on" parameter. This should not have prevented it from being loaded, but it was an error.

Using this configuration:

Code: Select all

dtdebug=1
dtoverlay=spi1-1cs,cs0_pin=16,cs0_spidev=off
dtoverlay=ads7846-spi1,penirq=5,penirq_pull=2,speed=50000,swapxy=0
dtparam=pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900
post the "sudo vcdbg log msg" output (which will now be more verbose) and the output from "ls -l /boot/overlays/ads7846*".

i allready did that without dtdebug=1, but Touch seems to be working right now.

However, its upside down, can raspberry change its orientation ?

Please describe carefully what is upside down relative to what.

thank you for your patience and help during this fase ! :D

well if i press top left corner of the touch the cursor moves to de right lower corner so touch is upside down relative to the LCD (have rotated the image Display_rotate=0 (standard is display_rotate=2)

With "display_rotate=2" does the touchscreen match the image (but with a rotated image)?

Does "lcd_rotate=2" (instead of "display_rotate=0") work (see viewtopic.php?p=815847#p815847)?

Yes, Correct only seems to be a little of in the middle, but calibration will do the trick i gues :-)

how ever when i put the rotate back to 0 the touch is upside down again

So this is a SPI based touchscreen, on an LCD panel, but not one of ours?

Quite a few TS drivers I've seen have DT parameters to do swaps/mirrors. Quick look at the kernel driver shows there is a boolean DT parameter

`swap-xy`

Does that work? (See drivers/input/touchscreen/ads7846.c for all the DT parameters)

The swap-xy parameter swaps the axes - x becomes y and vice versa, whereas we want to invert both axes.

As I understand it, lcd_rotate reprograms the panel to change the orientation, which is more efficient than rotating the framebuffer, but I can see why it may not work for an arbitrary display.

You may instead be able to tell the Linux/X input system to invert both axes.

guys thank you both for you amazing support i really appreciate it :)

but the solution to this problem was super simple, just as simple as just calibrating the touchscreen :oops:

everything is working fine now, and this methode is proving to be working !

cheers,

heyoo,

i know this is a old thread but im kinda new to this and im having problems getting this https://www.amazon.de/gp/product/B01F3J ... =UTF8&th=1 running on spi1using same pins on a Pi3 Model b+ (spi0 is used by a RFID reader). I pretty much followed all other steps ive seen here but the touch function still wont work. I tested the display on a 2nd Pi on spi0 and it works fine. any help would be appreciated.

Re: ads7846 on spi1

Sun Dec 08, 2019 8:37 pm

I can't see anything wrong - there must be a lot right for the driver to load. It's more likely that there's a fault in the wiring.

Are any interrupts getting through?

Code: Select all

$ cat /proc/interrupts | grep 167
ought to show a number that increments with every touch. If it doesn't, try artificially grounding GPIO 5 to see if that does anything, then check the IRQ wire.

i was actually testing the irq wire on diferent pins while using spi0 which worked. also checked the wires a few times since i try to get this to work since a few days already and it slowly drives me nuts XD

Is there an entry for the touchscreen under /dev/input? Can you ever read any data from it?
