### Notes
|
||||
|
||||
This sample uses an Adafruit INA219 breakout board and monitors a LED wired into the 3.3 volts supply with a 150 ohm current limiting resistor. It prints the bus voltage, shunt voltage, current and power every second.

|

* The maximum possible current would then be 40mV / 0.1 = 400mA
|
||||
* With a 400mA maximum current and a range of the ADC of 15bits then the LSB of the current would be 400mA/32767 = 12.2207 microamps. We will chose 12.2uA as a round number.
|

* From the [INA219 Datasheet](http://www.ti.com/lit/ds/symlink/ina219.pdf) the calibration register should be set at 0.04096/(currentLSB * shunt resistance) = 33574 = 0x8326
