The Raspberry Pi Pico has a similar price to the Blue Pill and seems a much
better machine for this task, although I haven't combed through its
reference manual yet.
For capture and writing (if that's part of the design) I heard there's a
dedicated coprocessor for the GPIO pins. It might be useful for
offloading some of the proccessing from some external circuitry to do
the capture or output.
I don't know what's included for the capabilities. And apparently since
the chip is new, there's only assembler programming for it now.
There's a video comparing the Pico, ESP32, ESP32-S and Blue Pill. The
latter was a bit low in resources compared to the others.
I'll try to find it and post it if anyone's interested.
thanks
