Streaming to GPIO
Posted: Wed Aug 10, 2022 10:01 am
Hello,
I wish to use the Red Pitaya to repeatedly send a predefined pattern to GPIO ports when triggered externally.
Have tried making C-program on the Zynq, polling the trigger line and then setting GPIO pattern, but this gives of course to much jitter, so it must be performed in the FPGA code.
According to https://redpitaya.readthedocs.io/en/lat ... b-projects, the stream-app project support streaming of GPIO, but we find no SW examples of that.
So my question is, can anyone supply SW examples of streaming to GPIO ports controlled by a trigger signal using any of the available FPGA images?
Thank you
