Touch not working. - Githubissues

githubnu9 commented 3 months ago

Hi,

Touch is not working for me. I'm using the 8048S070Cv13 (but same for my 8048S050R). I checked the touch controller and it is GT911. The factory image worked with touch so i know that the touchscreen is not broken.

I tried the example code and pushed the Button Add 1, but it does nothing. I also made another squareline project with a button which gave the same result. Touch does work when testing the project in squareline though. For reference I used default_envs = esp32-8048S070Cv13 in platformio.ini, but using esp32-8048S070Cv11 did not help either.

Did anyone experience the same? Or is there a solution?

Hi Githubnu9,

I have it now... Before it worked... Will try to find out why but now working on the develop branch...

githubnu9 commented 3 months ago

hi rzeldent, thank you. I tried develop with these three boards:

default_envs = esp32-8048S070C
#default_envs = esp32-8048S070N
#default_envs = esp32-8048S070R

but did not work unfortunatly, i will follow this issue for updates

rzeldent commented 3 months ago

Fixed it, Try the develop

githubnu9 commented 3 months ago

i did try to update the lib and reflash the 3 different 7 inch types. unofrtunatly no touch still. my 5 inch gives a blank screen now

i have bought these with Capacitive touch if that helps: https://nl.aliexpress.com/item/1005004952726089.html?spm=a2g0o.order_detail.order_detail_item.7.1a346d76o1nnfv&gatewayAdapt=glo2nld

Did you also updated the boards submodule?

githubnu9 commented 3 months ago

ok it looks like to work with my own squareline project

rzeldent commented 3 months ago

BTW try the 5". There was a typo in the back porch. Values from another board. (Update the json boards)!

Touch has improved but looks like the touch controllers are not aligned with the pixel resolution. Experienced this myself using a esp32-8048S043C. Touch controller reports: [ 478][I][lvgl_gt911_i2c.c:192] lvgl_touch_init(): GT911 xResolution / yResolution: (480, 272)

for a 800x480!

So the internal configuration of the touch has to be updated to match the resolution. This is for the GT911 drivers...

Hope this will get rid of the problems.

githubnu9 commented 3 months ago

so there seems something odd with the touch registration. i made aproject with a large button to test. if i press very much left of it then it will register as clicked on the button is this something to do with calibration? afbeelding

rzeldent commented 3 months ago

Might also be swapped... That can be fixed with the TOUCH_SWAP parameters in the json

githubnu9 commented 3 months ago

well that did something lol, now i have to touch on other random places. did not fix it

githubnu9 commented 3 months ago

with the 5 inch I now get

.pio/libdeps/esp32-8048S050C/esp32_smartdisplay/src/esp32_smartdisplay.c: In function 'lvgl_update_callback':
.pio/libdeps/esp32-8048S050C/esp32_smartdisplay/src/esp32_smartdisplay.c:83:61: error: 'TOUCH_SWAP_XY' undeclared (first use in this function); did you mean 'TOUCH_SWAP_X'?
     ESP_ERROR_CHECK(esp_lcd_touch_set_swap_xy(touch_handle, TOUCH_SWAP_XY));
                                                             ^~~~~~~~~~~~~

I did not enable Touch_SWAP, just a clean download of the develop

rzeldent commented 3 months ago

update the boards git submodule. That's a new define

githubnu9 commented 3 months ago

I re-downloaded everything:

Looks like the boards submodule directory is on main, it should also be on develop. Build passes: https://github.com/rzeldent/esp32-smartdisplay-demo/actions/runs/7682420001

githubnu9 commented 3 months ago

thanks the updating worked with develop. but touch is still not where it is supposed to be. i tried different settings for

      "'-D TOUCH_SWAP_XY=true'",
      "'-D TOUCH_SWAP_X=true'",
      "'-D TOUCH_SWAP_Y=false'",

but could not make it work

I can flash the 5 inch again but screen stays white

rzeldent commented 3 months ago

Any progress, what is the status?

githubnu9 commented 3 months ago

7 inch works good with:

      "'-D TOUCH_SWAP_XY=false'",
      "'-D TOUCH_SWAP_X=false'",
      "'-D TOUCH_SWAP_Y=false'",

:)

the 5inch is still blank.. hmmm

rzeldent commented 3 months ago

Hi,

Regarding the 5 inch, I looked at it again and seems to be according to the schematic. Only found the Red and Blue swapped in the esp32-8048S050N version but this can not be the issue...

So not much progress there...

rzeldent commented 3 months ago

Has been fixed in https://github.com/rzeldent/esp32-smartdisplay/tree/develop
