Hello,
I have recently been having a few issues regarding the use of the two analog pins available on the Sense shield with an ESP32-S3 :
Basically i am building project where i am using every analog pins possible on the classic Xiao ESP32-S3 which means that i actually need one of the two pins on the shield to do analog readings for a potentiometer.
However i have been met with the issue that i cant seem to get any of those pins to do any analog readings.
First of all on this page : Pin Multiplexing with Seeed Studio XIAO ESP32S3 (Sense) | Seeed Studio Wiki , it is suggested that these pins are capable of analog readings but that you need to access them using their GPIO names as opposed to their macros (such as A11 and A12).
The first confusing thing is that this page gives opposite indications on those GPIO names, check out the yellow boxed text in the step 1 and step 3 of the “For Sense” section. One of them tells to use GPIO 12 and 13 and the other 42 and 41 :
Anyway after testing and using any of those GPIO, i wasn’t able to get any analog readings from those pins, also note that i did cut the traces on J1 and J2 as indicated in the wiki.
Could anyone help me understand this issue?
Thanks you for reading !
