[SOLVED] Accessing ADC pins in UP2 board

adityahg77

I want to interface couple of analog sensors to UP2 board. How to access the 4 ADC pins available on the UP2 board? Also would like to know if there are any python library available for accessing ADC pins.

As far as I know he UP2 does not have any ADC pins only the UP has 1 ADC pin.
And even if it had some, there is no mention of ADC pins in the pinctrl driver for the UP2, so you would not be able to use them.

ADC pins are mentioned in some places, but only for the version with the Atom E3940 (which is not available at the moment afaik?), so unless you have that, you are out of luck.

Hi @adityahg77 ,

As @nukular said, UP2 board doesn't have ADC available. Check the pinout specifications:
https://wiki.up-community.org/Pinout_UP2

Also, "2nd SPI and ADC will be available only with E3940 SoC":

Cheers!!

Hi @nukular and @ccalde,
Thank you for the information.

Hi @nukular and @ccalde

I want to interface a couple of analog sensors with UpSquared, I understand that there is no onboard ADC on UpSquared. How about interfacing an external ADC with UpSquared just like Raspberry PI ? any suggestions on how we can do that?
