“Bare metal” CircuitPython on a Raspberry Pi, HDMI, and e-ink :)

Ok! This is super fun, Scott is working on a port of CircuitPython that runs on “bare metal” on the Raspberry Pi. So of course I wanted to see what works with HDMI since we can show the REPL… and I happen to have an e-ink HDMI display. It’s AWESOME.

One of the plans is to make a little computer with a keyboard, that is just CircuitPython. Write code, make art … with HDMI, have the output go to a little portable projector… kids could make cool kaleidoscopes, or make a Haiku computer that shows the last one made when the power is off since this one is e-ink 🙂

Code is here for now, and watch Scott’s Deep Dive each week at 5pm EDT on our socialz’ for more! – video.


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.

  1. This will make all my test rigs at work much easier to implement! I know you have resisted so far, but I recall threading was on the horizon, and this would be the perfect destination. I will be implementing this quite quickly into things. Yay!!!!

  2. I fully endorse this effort! Can’t wait to see how it turns out.
