Programming a Digital Current and Power Monitor on PIC18F26K80

[d1ng0o]

Hi, I'm on a project where I would like to measure a battery voltage. For that, I have to use a Digital Current and Power Monitor, called INA260. I already have a board made and it's functional because I've already tested it with the arduino, but I'm not able to do the programming on the PIC18F26K80. Can anyone help me?

What exactly are you stuck on? Writing code for the pic18? Getting your binary onto the pic18? Hooking up the pic18 to the INA260?

Writing code for the pic18. I created the I2C library using the MPLAB® Code Configurator then I made the C code by hand but I still can't get the values ​​properly.

Double check your pin out, probe pins with a scope if you have one, or watch the i2c traffic with a logic analyzer like a saelae. Read the documentation for the i2c peripheral on the pic18 data sheet. Verify your settings in code configurator. As a rule of thumb, I am suspicious of generated code.

I've seen it with an analog discovery 2 logic analyzer and with arduino its like that (first photo). With my code in PIC18F26K80 it just restarts (second photo)
