+   The INA219 is a high-side current shunt and power monitor 
+   with an I2C interface. The INA219 monitors both shunt drop
+   and supply voltage, with programmable conversion times and 
+   filtering. A programmable calibration value, combined with 
+   an internal multiplier, enables direct readouts in amperes. 
+   An additional multiplying register calculates power in watts. 
+   The I2C interface features 16 programmable addresse
