PS2-TTLserial adapter for RC2014 and MIDI

Posted on Monday, October 30th, 2017 in AVR, hacks by DP

PS2-to-ttlserial-midi-600

Dr. Scott M. Baker published a new build:

The original reason for this project is that I wanted to build a standalone RC2014 with keyboard and display. There is an official RC2014 serial keyboard, but I find it a little inconvenient for my big fingers and poor eyesight. I have plenty of old PS/2 keyboards laying around, so I figured I’d rig up a microcontroller to convert the PS/2 keyboard interface into a TTL-level serial interface that could be plugged directly into the RC2014’s serial port.
Along the way, I discovered that the very same circuit would make an interesting project to turn a PS/2 keyboard into a simple MIDI controller. So I adapted the circuit for that purpose as well.
