PWM and SPI peripherals



Hello list,


Does anyone manage to get PWM or SPI working?

I need one of them to control Neopixels.

I have tried [1] and compiles correctly but it fails when running the included `test` program because the `/dev/vcio` device (for PWM) does not exist.

The same thing happens in [2] when using Ubuntu, and he proposes to use SPI, but it didn't work for me because there is no `/dev/spidev0.0` device.



Details:

- raspberry pi 4 - 4G
- image from https://raspi.debian.net/tested-images/
