NGW100 with WS2811 LEDs
I've bitbanged i2c on AP7000, but I think 100 kHz was around the resulting output. You do have the SSC peripherals in AP7000, perhaps you could write a kernel driver that does...

SPI overruns caused by RS232 transfers
DMA transfers through SPI is a bit stupid, is for some reason the SPI controller is not feed data when requested it will send garbage. If you at some time are passing data for the...

SPI overruns caused by RS232 transfers
Also, remember that if the SPI controller is not feed data quick enough, then it will send gibberish on the bus. It doesn't do clock stretching. That is why I would recommend...

SPI overruns caused by RS232 transfers
Not likely source code bugs, but hardware limitations. The SPI controller will not stretch in DMA mode if not feed data fast enough, hence you'll see problems. You can solve this...
