Bela no PRU

Some example code to use the Bela ADC/DAC and audio codec without Bela's PRU code. This could come in handy if you are using the Bela cape with the BB-AUDI-02 overlay on the BeagleBone or PocketBeagle, or the Bela dtb on the Beaglebone AI.

Use ./build_all.sh to build the adc/dac examples. Then run the examples with sudo (as it's required to export the chip select GPIOs). This requires having the Bela code on the board at the usual location ~/Bela.

To change the soundcard's settings (e.g.: gain, output level) when running with ALSA, use alsamixer.

You can’t perform that action at this time.
