I’m having an issue and could use some help. In short, my Raspberry PI is shutting off when I blink a LED light using GPIO pin 17.
Very excited to start using the PI Sound card with my Raspberry PI 4b.
I am using pure data with an external to control the GPIO pins: GitHub - garthz/pdwiringPi: Pure Data (pd) external for hardware I/O on a Raspberry Pi using wiringPi.
I have a LED light soldered to GPIO 17 and am toggling it using the pure data metronome.
The light turns on and off with the tempo and everything is peachy. However, I notice that when I stop the metronome, the MIDI lights start blinking… Curious. Eventually, with enough metronome activity, the Raspberry PI shuts down!
It looks like something about the GPIO 17 activity is calling other functions to run?
Why are the MIDI lights coming on when there is no MIDI activity?
Is this a known issue with the PI Sound card?
Has anyone else used the GPIO pins for powering LEDs?
