There is also ulab but that requires compiling the firmware.

I use uasyncio with this debouncer rather than using interrupts.

Converting from JPEG to a bitmap involves a lot of mathematics: the JPEG format is highly compressed. Options are to find a library which can do the conversion on the Pyboard, use a different file format, or - if you just want to display an image - use a display which can handle JPEG streams nativel...

You will need eight asynchronous routines. Whether these are functions or bound methods depends on the way you plan to share data. This is down to general programming practice - bound variables or bound objects are generally better practice than using globals.

Debouncing? Unless the touch controller datasheet says otherwise it shouldn't be needed: contact bounce is a feature of mechanical switches.

If you're using uasyncio - which is usually the best approach - you should use the stream mechanism which handles concurrency and buffering.

... If you're talking about the PIO controllers, my understanding is that they run independently of _both_ main cores. i.e. they are in a sense their own independent microcontrollers with DMA. Indeed. The PIO comprises two blocks, each containing four independently programmable state machines. The ...

I have developed GUI's for three different touchscreens, using the same general approach. Hardware interrupts are not used. The touch controller is polled by a uasyncio task which runs continuously. An example may be seen here . The responsiveness is fine. In my view interrupts are only necessary wh...

... Got it, thanks. There appears to be a discrepancy between utime.localtime() and machine.RTC().datetime()... There is. utime.localtime matches CPython's time module. Unfortunately RTC.datetime() - which isn't even documented - adopts a different convention which is based on STM hardware and the ...

The programmable I/O sounds particularly clever. I'll try to track down some docs...
