I see in the GPG hardware & port description page that there are pins for upto 3 analog sensors (supposedly meant for line sensors). However, I cannot find information on how to use them. These are the pages I’ve looked at:
Also, the GPIO pins are digital so I can’t use them directly for analog signals. For now, I’m trying the RC-circuit workaround here:
Is there any place which has information on how to interface with the analog pins?
