I had something like this in mind. This assumes you've installed the Switch primitive as per the docs: from machine import Pin import uasyncio as asyncio from primitives.switch import Switch from time import ticks_diff, ticks_ms tstart = None delta = None # Callback on debounced switch closure def t...

There is also nano-gui which has a driver for ILI9341.

Unfortunately some of the widgets don't work with the Pico because currently the Pico lacks the cmath library. Hopefully that, and other similar issues, will be fixed soon. Only the circular widgets and the graph plotting module are affected.

See this repo.

Just in case you guys haven't got there first...

It took me a long while to get it to jump on a pin. The trick is The documentation for this is here which gives a clue about other args.

Does this, from the SPI example in the Python doc, give a clue? self._sm = rp2.StateMachine(sm_id, spi_cpha0, freq=4*freq, sideset_base=Pin( pin_sck), out_base=Pin(pin_mosi), in_base=Pin(pin_sck)) The Python doc is seriously lacking :( [EDIT] My understanding of I/O is that input and output pins mus...

Perhaps I didn't express myself well, but none of that contradicts my post. I didn't mention the multiprocessing module because MicroPython has no equivalent. Threading does solve the problem of blocking I/O, both in CPython and MicroPython. However, in MicroPython at least, it is much more efficien...

Good point. I've added a note to that effect.

I've found this on P24 of this doc : You need to specify an initial OUT pin state in your program in order to be able to pass OUT mapping to your SM instantiation So it defines the level on the pin before you set it; with hindsight I guess this is obvious. It still doesn't make a lot of sense for an...

I have been playing with this script from the official demos: import time from machine import Pin import rp2 # Define an empty program that uses a single set pin. @rp2.asm_pio(set_init=rp2.PIO.OUT_HIGH) def prog(): pass # Construct the StateMachine, binding Pin(25) to the set pin. sm = rp2.StateMach...

Alas I can't read the Chinese README, so I may be wrong. But this appears to be closed source. If so, this is a pity as framebuf enhancements are of general interest.
