First of all, thnx for all the superb work you did with WLED etc ! At the moment i’am busy try to get a ESP32Cam board to function with ESP (Dev) and the ESP32\_TouchBrightnessControl mod. Compiling seems fine, flashed this firmware on the ESP32cam board also works perfectly . But then …I tried the touch control with a simple wire on the GPIO 4 port but no response at all. So at this moment I was googling around for some moments but can’t find the solution of what button (except the default ESP touch functionality) is used for this option. Is there somebody who can help me with this ? ---

I think it’s for the top/can of the module. ---
