Title: help making a 60% keyboard with a teensy 3.2?
Post by: Ace_Entity on Thu, 21 July 2016, 17:23:42

after accidentally breaking the pcb in my keyboard build with an unfortunate soldering accident, i decided to use a teensy instead of a traditional pcb. it seems like it'd be way easier to repair even though wiring it yourself is way harder than putting all the parts into a pcb. iv'e been using this https://deskthority.net/workshop-f7/brownfox-step-by-step-t6050.html tutorial for everything so far but i still for the life of me can not figure out what to do when it comes to the actual teensy. i don't know which wires connected to the rows and columns of keyswitches to connect to which contacts on the teensy, and i don't know what to do on the software side of things when everything is wired up. here is what i have so far http://imgur.com/T9R9muu all i have to do now from my understanding is wire the rows and columns to the teensy and set up the software. sorry if im being stupid in any way, i was referred here by someone on the mech keyboards subbreddit (this will be my third post regarding this project). thanks in advance for the help!

Welcome to GH :)

If you were wondering why no-one's helping it's because of the Teensy you got - the 3.x Teensys use a different chip to the 2.0 so there isn't any firmware available for it.  If you're a programmer, or would like to be, carry on and write your own - you can connect the rows and columns to any of pins with a number label.  Remember where each is connected to as you'll need this in your code.

If you're not an (aspiring) programmer you would be better off with a Teensy 2.0, then you have a choice of EasyAVR or TMK.

thanks for the heads up! when i saw a tutorial using the 3.2 i just assumed it was the best one for the job. this is the most complicated tech project iv'e ever attempted, but i did just finish my first year of a java programming class in school so i do have some insight, and through all the research iv'e been attempting to do, the whole thing has interested me a fair bit. i might just go back to microcenter and return it, but this project isn't really very urgent at all so i might also just try and learn how to finish it. i really appreciate the help!

TMK supports the Teensy 3.2. Look at the Teensy LC Onekey example. It can be compiled for for the Teensy 3.2 using the correct Makefile.

It also appears that kiibohd controller (the firmware used in the Infinity Keyboards and Whitefox) supports Teensy 3.2

Here's some info on how to set things up:
