Teensy 3.1 firmware and Hand wired keyboard help

Hey everyone,

I'm new here to the forum and I've come here to ask for help regarding a homemade keyboard project I'm trying to complete.

I decided to hand wire my keyboard just because I wanted to get the soldering experience and I picked the Teensy 3.1 since it had enough pins to support the rows and columns I had planned for my keyboard and it was a pretty good price.

I have the keyboard and the teensy all wired up but I'm not sure how to proceed in terms of firmware. I already have Arduino and Teensyduino installed on my computer.

Can you guys suggest some good (easy) firmware options and give me a small tutorial on how to get it working on my setup?
Also does my wiring look good?

I greatly appreciate any advice anyone could give me.

I've included some pics of my current work:

I made my own 60% handwired keyboard a while back and found TMK was fairly easy to get working on a teensy 2.0. I had only limited experience with programming microcontrollers at the time.

Thanks for your input bentglasstube, I'll take a look at that one.

I tried using the Arduino Keypad library with no success, it's printing a bunch of crap to serial in my example I have. I'm also thinking that my wiring may be messed up somewhere.

Does anyone know of a way to test my matrix with a multimeter other than continuity testing each dot in the matrix?
