That seems too slow.The best I was able to achieve on Pi5 was a 10-15 KB/second transfer rate, using either the OpenOCD linuxgpiod driver (which is not compiled in by RP) or the sysfsgpio driver.OK, I'm confused now; that sounds like a big problem. Could you explain briefly?
Is it possible the RP1 chip used for GPIO on the Pi 5 has enough (undocumented) programmable I/O capability that the bit banging could be done more efficiently?
