Thank You Felmue.
The source code that is mentioned in the post you linked should be run in arduino ? Thank you

HI everyone ! I have bought M5stack with the objective of connect with INA226 and measure energy consumption. I have read the article on digikey https://www.digikey.com/en/maker/projects/use-m5stack-to-measure-power-consumption/00d20499f5e047fe86ab310cce0cb0c1 .
Anyway it is not clear to me which program to run on M5stack in order to measure energy consumption. There is not any info on this article. Can you please suggest me or give a tip ?
Thank you very much.
Bye

HI!
I would like to measure energy consumption of arduino connected to a sensor.
Should I buy the M5stack basic core or other ?
