PyDOS tests out CircuitPython running on 'bare metal' Raspberry Pi SBCs #circuitpython

PyDOS is moving to the Raspberry Pi RP2040 Pico's big brother. Today, I'm demonstrating PyDOS running on CircuitPython's Alpha build for the Broadcom (Raspberry PI Zero 2W SBC) chipset.

The Python and Basic code demonstrated can be found on GitHub at:

PyDOS is just awesome! I'm an old DOS user and had embedded systems running with MS-DOS on it. I still think that some form of DOS would be far easier for beginners and makers for simple tasks. Someone don't need a full featured Linux on a SBC to blink some lights or read some sensors. And running PyDOS on a MCS is somewhat a revolution in my eyes, as MCS are not intended to run an OS. I will definetly look into your work, that's for sure. Keep up the good work and you might want to get into contact with the FreeDOS community to show your work and get some ideas. The FreeDOS community is looking into new ways to develop their OS to and I suggested to target embedded systems. Your work is showing what can be done and an exchange of ideas would be most interesting to see and follow.

Nice! Now would be the time to write a DOS for a bare metal Pi ;)

It seems like you are leaning toward the Raspberry Pi Zero 2W? How did you wire that? Is there a wiring diagram somewhere? I have all the parts. I could build it as a Feather S2 or a Pico. I have all 3 boards, but you seem to lean toward the Zero 2 W board.

Your video is interesting and it has some "Good Information".

Your "Audio is just painful though".

Try to keep the microphone at a constant distance, don't turn your head just keep the same orientation, cadance and tone.

Distance a d head movement seens to be the most important.
