Topic: INA219 power measurement
Today I added a power measurement board in between the 3.3 volt and the complete breadboards where all my sensors reside.
As I could not find any working C code on the net I used a Python library instead.
I had to shorten A1 as address 0x40 was already in use by my HTU21.
Now its set to 0x44 so also adjusted the Subfact_ina219.py
__INA219_ADDRESS = 0x44
See here : https://github.com/scottjw/subfact_pi_ina219 for the Python code.
Its working nicely : http://pi.gids.nl:81/temp/gauges.php
If someone has a C code tool I would be interested in it to try out and compare performance.
