Anyone considered trying to run a real time operating system for the pedal pi?
Would it actually produce any benefits I wonder? My Pedal-Pi has substantial crackling/noise but I'm still debugging my setup.
Seems like a solid place to start: it has support for SPI, C code, threading, ADC, DAC, and BCM libraries.
Or maybe this a waste of time moving backwards towards the Arduino Boards.
One interesting possibility would be if someone could create a network stack and serve out a touchscreen webpage for smartphone control while still maintaining low latencies for the DSP
When I started with the project I had a look at the RTOS out there, but at that time it was difficult to find something good with the PI Zero that gives functionality and good capabilities. In the end, I went for the "default" Raspbian, but I am sure that an RTOS will give a better audio experience as the ADC/PWM interrupts will be just spot on in time.
The only problem is the amount of software development needed...
