I wanted to use an ina233 from a Raspberry Pi and found in these forums that there was no example code for the ina233, no Linux kernel support for the ina233, and a lack of existing python module so I was forced to create one. I apologize if it is not appropriate to post this in a new thread, but the thread where someone had asked about existing code was already locked so I couldn't reply.
Find it here: https://github.com/scottvr/pi-ina233
I hope this is useful to someone.
