NeoKey 1x4 + RP2040 (Raspberry Pi Pico) "Multitimer"

Post by ratfactor »

I build a little categorical "productivity timer" using the NeoKey 1x4 keypad. I've been using it for a month and love the NeoKey keypad!

It's not much to look at, but it works great. :-)

I've got a writeup here: http://ratfactor.com/multitimer

What may be of particular interest to others is my pure MicroPython (as opposed to Adafruit's officially supported CircuitPython library) communication with the NeoKey (Seesaw) over I2C. The entire timer source is under 300 lines, so it's super easy to find the relevant parts. Here's a direct link to the repo: https://github.com/ratfactor/pico-multitimer
