Hi, I just bought a ESP32-4848S040

Do you think you can make it work for your Software?

Starting application Config version: 0 Clearing Global Config

With no debug on

[franki29]

So it is stopping after clearing config

[Smanar]

So there is no more crash, but not working ? Or it freeze now ?

After "Clearing Global Config" it set the display, so the touchpad and the display.

Or you mean with all debug disabled ?

[Smanar]

Ok so this time was my fault. Have re write the touch code for all device, It will still crashing I think, but this time we will have logs.

Can you tell me how it s with debug disabled ? all are enabled by defaut, so no crash at first try.

[franki29]

So when I try to select the network, nothing is happening

[Smanar]

Ok so it mean all was my fault, sorry, was not a problem with your device (at least for the touchpad). Now we have all logs, and the lib is running without crash. So I think this lib can work now, I have updated the code again

Starting calibration
Calibration coef: inf , inf
Calibration offset: nan , nan

If all is fine you will have value now here, else I m wrong again on my side. And thx for your patience.

[franki29]

Now calibartion is not shown.

[Smanar]

Yes it's normal, it's because you had bad value but the calibration was finished on your previous test, so the device don't ask for it again.

On Platformio.ini file.

-DFORCECALIBRATE=true # Reset the calibration at every restart, used to reset it after a config change.

If you want I can make a special branch in "franki" with code specific to your device, insteod of using the "test" branch, but for me we are realy close the end.

[franki29]

OK I tried but still I can not select a network. After calibration of the screen, touch is not working anymore

[franki29]

: SUCCESS Starting calibration Calibration coef: 0.9 , 0.9 Calibration offset: 13.5 , 6.8 Display buffer size: 24576 bytes Screen init done WiFi Status: Disconnected WiFi Status: Disconnected

[Smanar]

Value don't look so bad. There is an hidden tool in the code in the screen driver.cpp file

#if 0
//Tool to test the touchpad, need to be disabled, only for debug purpose
while (true)
{
    p = touchscreen.getPoint();
    p.x = round((p.x * global_config.screenCalXMult) + global_config.screenCalXOffset);
    p.y = round((p.y * global_config.screenCalYMult) + global_config.screenCalYOffset);

    tft.drawFastHLine(p.x,p.y,2,TFT_RED);
}
#endif

Just replace #if 0 by #if 1 It will block the code, but just after the calibration, you will be able to "color a pixel" with pressing the display, usefull to see if the screen is not reversed, or a bad scale.

Edit: Wait a little, have found a problem.

[Smanar]

Have upodated the code again, you can let -DFORCECALIBRATE=false

for me your last try was fine.

[franki29]

Bingo, now it is working:-) Thank you very much

[Smanar]

Ha finally ^^. I let you make tries, according your resolution, I think thoses one need to be adpated

    -DTOTAL_ICONX=3 # How many icon widht
    -DTOTAL_ICONY=3 # How many icon Heigh
    -DDEVICE_SIZE=1 # Device display size

And I think soon, you will want to use the relay.

[franki29]

Hi, no I do not want to use the relay as the size of the device does not fit in European wall plugs and it does not have CE

[franki29]

But you can use the device separate from the relays part. Only for the power I have to think what solution I will go with. I do not want to use the USB for Power, so I want to use a mini Power Supply that fit into the wall whole.

[Smanar]

Ha yes, this one don't need power module. I live in France and we can found square box or round but bigger https://www.elecproshop.com/12687-boite-de-derivation-cloisons-seches-ronde-diam-85.html?srsltid=AfmBOoqDipySMQ4TyZtUUFsx-kz9igAN74-KVhat4SJe0qQvd7a6TCfkQQA
