Hi,
I'm currently in the middle of doing my bachelor thesis and am trying to realize a signal generator using the HifiBerry.
So far I've only programmed GPIO and DACs on a LPC1758 with and w/out rtos, which comes with fitting libraries for C, can anyone point me in the right direction which libraries to use to directly write output to the HifiBerry.
thanks

HiFiBerry team Hi Johannes,
interesting project. Show us more when you have it ready. From the programming side, the DAC is a normal sound card for linux. You will use ALSA to send audio data to it.

There are no HiFiBerry-specific libraries, just ALSA.
