Title: Thoughts on using Teensy-LC for keyboard build
Post by: Dihedral on Sat, 09 May 2015, 10:05:49

How well will the Teensy-LC work for keyboard builds? Are there any limitations of it that could hinder it's ability to work well as a microcontroller?

From what I can see, the only real limiting factor is the availability of firmware.
HaaTa's Kiibohd (https://github.com/kiibohd/controller) controller firmware supports the Teensy 3.0 and 3.1. The microcontroller in the Teensy LC seems to be mostly compatible with those, just stripped down in its capabilities.

Edit: Oh, the pins' signalling is 3.3V, so every other chip you interface must also run on 3.3V.

I'm going to be using a similar chip the the Teensy LC in my build (MKL26Z still, but with more flash).

I'm going to be writing my own firmware, but I don't think it'd be such a massive task to get Kiibohd working, I just don't know if I'll ever do that!
