Hello,

We'd like to read the current values on the INA231 of the AM652x development kit (PROC114E2) in Linux. How do we do that?

Thanks.

Arg. This was posted in wrong forum group. Should have been for AM62xx.

I know what the addresses are, I was wondering if there was software to perform the I2C operations and print out the results, or if I had to write the software to do that?

Hi Michael,

We don't have an utility running in Linux on AM62x to reading these INA231. Internally we read them through the automation header on the board using a MSP430 Launchpad with an adapter card, however the adapter card is not available to the public.

FYI, here is the application used on MSP430 to read the INA231.
