Troubleshooting • Re: GPIO 13 (LED, kernel module PWM) and GPIO 12 (buzzer, WiringPi PWM) are experiencing a conflict.

Asking for WiringPi devs:
Can you please provide details on how to submit a request to support Pi5 in Raspberry Pi OS? Additionally, whom should such a request be directed to?

AFAIK the WiringPi devs haven't requested for a release supporting Pi5 to be part of Raspberry Pi OS, so I haven't followed what it does and does not do.

RP1 supports 4 PWM channels, but has a common enable register.
All users will need to ensure they do a read/modify/write to avoid disrupting other channels, but as there can't be a mutex between kernel and userspace for altering those registers, there will always be a race condition.

Check the pinmuxing first with "pinctrl get"
