Pi 3 - how to detect low voltage?

Mon Jun 19, 2017 11:07 am

I am trying to create a program to monitor my various Pi's, temperature, space, voltage, etc. Works for Pi 2 but voltage detection does not work for Pi 3. From info on an earlier post the voltage detection circuit was moved for the 3.
Can anyone tell me how to detect low voltage on a 3 within code?

Thanks
Mick

Thanks Dom,
I have done some digging around and there are lots of references to various vcgencmd commands, but I cannot find any documentation for it, listing all the commands and what they do. Do you know of anything?
