We have lots of hardware level programming experience on other platforms using c and Assembler. I do not have Linux experience. We are planning to target a raspberry pi zero 2 W but are currently using a 4 with 4 gig memory as the zero 2 W is out of stock at the moment. Fast code is essential as we will also be doing some dsp processing so that it can also react to music. Low level drivers may have to be written. Looking up this information via google is a jungle.
