That's impressive. I was suspicious until I saw the quad-byte DMA ringbuffer with the super small PIO program. He's overclocking to 200 MHz (!!!) and the framin

That's impressive. I was suspicious until I saw the quad-byte DMA ringbuffer with the super small PIO program. He's overclocking to 200 MHz (!!!) and the framing protocol does have bugs (see comments), but impressive all the same. Also the message buffer is pretty small but now I'm just being picky: streaming to UART while sampling wouldn't be possible without giving up some channels and slowing down the sample rate.
