    I am developping special app with this card and I would like to be able to fix the pot value manually (not using the 10K pot) this should be done trough serial command or ethernet to set the analog threshold
    Where can I modify this in the TV.out library to do this ?


    You can’t do it in code. The code has no concept of the analog input threshold. It’s a hardware thing. The potentiometer changes the voltage on a pin of the microcontroller. The only thing I can suggest is to integrate a digital pot or DAC which can output a variable voltage.


    Hi thanks for this prompt response, I should have see that by myself looking at schematic 😉
    I will check in this project if any pwm pin available and route it to th.e pot cursor
    Many Thanks
