Thank you so much arg001 for the response. Both pio->sm[sm].instr = 0x0000 | (0x1 + offset) and pio_sm_exec(pio, sm, pio_encode_jmp(1 + offset)) work!
The program did print out "Loaded program at 30" but I didn't really understand what that offset means. I keep thinking that the program will be load from address 0 but looks like the compiler actually aligns the program to the top of the SM address space.
I am not quite sure how to use this approach though:
I put a label "next" in the PIO program like this:
but that "next" label doesn't show up in instr.pio.h at all. The only two addresses being included are:Is there any way to make the labels in PIO program show up in *.pio.h file so that we can use them in C program?
