All the functionality of the 1981 IBM PC on a PI Pico? Close…

PyDOS is a MicroPython/CircuitPython DOS-like shell for microcontroller boards.

It has several familiar commands:

  • edit.py – line editor inspired by DOS edlin. Intial program structure of line editor by Joesph Long https://github.com/j-osephlong/Python-Text-Editor
  • fsedit.py – shell to load full screen editor from https://github.com/robert-hh/Micropython-Editor
  • fileview.py – scrollable text file viewer
  • sdmount.py (MicroPython only) – mounts an sd card to the file system
  • sdumount.py (MicroPython only) – dismounts an sd card from the file system
  • setdate.py (MicroPython only) – initializes the RP2040 real time clock to an entered date
  • settime.py (MicroPython only) – initializes the RP2040 real time clock to an entered time
  • diff.py – performs a file comparison
  • sound.py – outputs a sound to a speaker circuit connected to GPIO 19
  • lcdprint.py – displays text on an I2C LCD display
  • PyBasic.py – a Basic interpreter from https://github.com/richpl/PyBasic. Tweaked and modified to run on MicroPython. basicparser.py, basictoken.py, flowsignal.py, lexer.py, program.py, basicdata.py
  • runasthread.py (MicroPython only) – This program will attempt to launch a python program on the second RP2040 core. Threading is experimental on MicroPython so it’s not difficult to crash the microcontroller using this program. I have not found a way to kill a thread started on the second core so be sure any threads you launch will shutdown on their own or monitor a global variable or thread.lock to respond to a shutdown request (see the badblink.py for an example).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
