General discussion • Re: FPGA

Very few people are using the PIO to the max even on RP2040.

something ive been working out the math on, is using the PIO on the pi5 as a logic analyzer

i think it might be capable of capturing all 28 gpio pins at 50mhz, with a buffer as big as ram will allow
or 16 pins at 100mhz

and even then, thats just an `in 16` loop with wrap, its barely scratching what pio is capable of
more just maxing out what the dma controller can copy
(if i can get dma to even copy)
