• Just quickly looking at the datasheet:
    Do you set CS to high?
    Is your wiring good?
    Is the I2C address correct?

    For example, have a bunch of INA226 modules that don't use the default I2C address, and SDA and SCL markings on the breakout board are swapped...

  • Thanks for your help,
    1) CS is set to high according to my schematic
    2) Wiring is good as far as I can tell
    3) I2C address is correct as far as I can tell too, although I have tried many different ones and still get the WHO_AM_I check fail
