Current Sensing
###############

Overview
********
This is a sample app to interface with TI INA219 power monitor.
The values used in the app are for use on Adafruit's breakout board
(https://www.adafruit.com/products/904).

This assumes the slave address is 0x40, where A0 and A1 are all tied to ground.

Building and Running
