I am trying to add an InkyPHAT display to a Raspberry Pi Zero W with other devices on the I2C bus (specifically, a Sensirion SEN55 and a GPS unit from Adafruit). I notice that the mere presence of the InkyPHAT on the bus doesn’t affect the operation of the other devices, but the moment I load the InkyPHAT driver in Python every other device on the bus is no longer detected, even with
i2cdetect from the CLI.
Is this expected behavior? It doesn’t seem necessary that the InkyPHAT should have to completely own the I2C bus over all other devices.
