IoT pHAT Fails when ic2 bus used, need a solution


I am having issues where the IoT fails when the ic2 bus is used and need help with the solution. Thank you.


I can’t see any immediate reason why that would happen, however I think it’s possible that you may mean SPI bus, not I2C bus, if that’s the case, make sure your project isn’t using BCM17 (Pin 11), or BCM16 (Pin 36),

See:, and for more information.
