INA219 vs. INA226

[1technophile]

@PetricaM

Could you share your schematics for INA226?

Hello Petrica,

I used it with an esp8266, I don’t have any schematic to provide unfortunately nevertheless to connect your INA226 to pin 20 and 21 for an arduino mega seems fine.

@PetricaM

I know for sure the power supply provides 13.4 V and the device should draw about 1.2 - 1.3 A thus the expectations were that the readings were something like:
{"volt":"13.4","current":"1.2"} or, with the power consumption (however, it is strange that there is no reading on the power either) {"volt":"13.4","current":"1.2","power":"16"}

Could you try the sample INA226_simple from the INA226 library folder and see if it retrieves the expected values?
