AnonymousPi Posted August 11, 2020 Share Posted August 11, 2020 Hi, There have been a couple of posts about this over time, but I was wondeing if somebody could please provide concrete example / sample code that uses DMA to TX out the GPIO pin(s)? I want to be able to TX outwards only from my Allwinner H3 device (Orange PI PC) to 16 pins in parallel (so 16 bit DMA in parallel) from a chunk of memory in RAM. Happy with a basic example if somebody has which just blasts out one GPIO pin even. Link to comment Share on other sites More sharing options...
