  1. Made some progress on prototyping a #RP2040 based #USB Audio interface. I got a PIO program to output a good looking TDM signal for 4 channels of 32-bit samples.

    Now I can start prototyping the receiving end of the transaction, DMAing samples into RAM and packing them into isochronous USB packets.

    Thank you.
    I have the nagging feeling that it isn't absolutely, positively portable to use `unsigned long long' and `uint64_t' interchangeably, now and forever, but I Am Not A Language Lawyer (IANALL™) and that is off off topic anyway.

    I am sure that the implementation at hand that takes care of such embedding of C or C++ fragments is completely sane.
    I replied from the user's perspective, but aesthetics is in the eyes of the programmer, of course.
