Disable specific PIN for use by other hardware


Hi there,
Nice work using the Pi with the Particle Cloud. We are using the Pi with the Adafruit speaker bonnet (https://learn.adafruit.com/adafruit-speaker-bonnet-for-raspberry-pi). When I install the particle agent, there is no sound anymore. Does anyone know if I can disable pins such that the speaker may use those pins?

Thanks, Edge.


Based on the discussion here, I’m planning on changing the behavior of the pin initialization on the Raspberry Pi. Thanks for the feedback!


Check Raspberry Pi: Pre-release firmware with improved pin initialization to try the new behavior.
