Yes, I think they're more of a curiosity for many hacker types, but they definitely do get used. My Siglent SDG-2042X signal generator uses the same SoC, would guess it's using the PRUs to drive its DACs. A member of our local makerspace used a PRU to drive a big display made with shift-register RGB LEDs (something like a WS2812 - can't recall details). I have made a proof-of-concept interface to a fairly high end ADC that did a little bit of filtering in the PRU before sending the results to the main CPU. |
