Pico USB serial communications with CircuitPython

My Raspberry Pi Pico-based Motorola 6809 emulator uses the RP2040’s built-in serial-over-USB functionality to receive machine code sent from a host computer. The 6809 and its support code is written in C, but can you make use of the same process under Python? Yes, you can, and here’s an easy way to do it.

Program games on the Pimoroni PicoSystem

A wee while back I ordered a Pimoroni PicoSystem to try out. It’s a small handheld games console based on the Raspberry Pi RP2040 microcontroller, and it sports both classic joypad controls and a 240 x 240 16-bit colour display. I gave my first impressions in an earlier post. Here’s what I think after spending some time porting my Raspberry Pi Pico version of the 1980s 3D shooter Phantom Slayer to the unit.
