Following the other thread on GPIO made me wonder how stable that approach was going to be, so I went looking around and came across this: https://github.com/Wallacoloo/Raspberry-Pi-DMA-Example/blob/master/dma-gpio.c
Having DMA handle the GPIO writes removes the CPU from the equation, and his approach of interleaving writes to PWM to provide control of the data transfer rate looks promising, to my under-informed self anyway. I think I recall this being discussed before.. Did anyone ever go further with this? Would it be feasible to feed that from Machinekit? Reliable high data rate GPIO on the PI could result. -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
