Concerning circuitpython.displayio it is a .cpp module that is compiled with circuitpython so it can't be added as is in micropython. In my opinion, the fastest way to do it is accessing the registers of the microcontroler using machine.mem32. With mem32 you can read/write directly in the registers....

You can easily change the format.
1) you may need to change the masks depending on which color is coded over 5 or 6 bits
2) you then change the order of the parameters in the last operation to place the 3 colors at the right place

Perhaps a less convoluted solution Python 3.8.10 (default, Jun 2 2021, 10:49:15) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> r = 0xcf >>> g = 0x78 >>> b = 0xa3 >>> # mask the unused bits >>> nr = r & 0xf8 >>> ng = g & 0xfc >>> nb = b & 0xf8 >>> pri...

The frequency of the PWM has nothing to do with the one of the signal you want to synthesize. Apart than the frequency of the PWN shall be way higher than the one you synthesize. You should use DDS to create your signal. DDS stands for Direct Digital Synthesis. Say you have a large accumulator you c...

Many possible solutions:
1) as Aivar suggested, switching to Thonny 3.3.11
2) taking on living with this error from time to time
3) taking a rest on sunday, so you 'll never encounter the problem

Interesting project but maybe you can add comment at the end of the display.draw_chinese() calls with a translation of the text so non chinese people can adapt the software to their need.

flash_nuke will erase all the flash. if the problem is only an "uncontrolled" main.py there is a less damaging solution. https://www.raspberrypi.org/forums/viewtopic.php?f=146&t=305432 MicroPython_RenameMainDotPy only zap main.py and preserve the filesystem so if you already have any file saved on t...

Thonny try synchronizing the RTC when it connects to the Pico. To do this it sends a short piece of code to the Pico, the problem is probably there.
Maybe @aivarannamaa can confirm.

Your are talking abour a speaker, maybe you can describe your configuration in more detail, it will be easier to help you

Garbage collection perhaps.
