Is there a simple way to use DMA to control pins on a RasPi 5? I have some code working using pigpio, on a 3 (basically 4 channels of pulses to control 4 ws2812 strips)... but that doesn't work on the RasPi 5.

  • what code do you have? Maybe you should show it. What means doesn't work? Do you get error? You should show it in question. Don't expect that we will write all code from scratch. Commented Mar 6, 2025 at 1:55
  • maybe you could ask on similar portal Raspberry Pi or on official forum Raspberry Pi Commented Mar 6, 2025 at 1:56
  • pigpiod won't start on a RasPi5... a known problem since RasPi5 changed the GPIO completely. Dunno if there are any better ways, if someone were to tell me how to DMA using python on a Pi5, that would be enough. Or if there's a good enough better way. I've already done set_realtime_priority and... it's not good enough. Commented Mar 6, 2025 at 22:19
  • people on other portals may have better experience with RPi and DMA. Commented Mar 7, 2025 at 5:10
