I wrote a driver for the adafruit charlieplexed LED matrix using micropython. In this post I document all of the steps required to upload this driver to a teensy. It may be useful to others interested in getting started with micropython.
LED Charlieplexed Matrix – 9×16 LEDs: These are 9×16 Charlieplexed LEDs designed to match with the Adafruit 16×9 Charlieplexed PWM LED Matrix Driver – IS31FL3731. You don’t get any resistors or driver chips with this grid, its just a mess of LEDs in a charlieplexed arrangement. (read more)
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
