3 years ago Just add the new address in the Header file. You can do that by opening the header file in Notepad by defining the new address You might need to tweak some code in Header as well as CPP file.
Hi.. I have a problem to use 2 module INA226 with protocol I2C. I write this sketch but it doesn't work. the Arduino IDE give me errors. Can you help me?
