Arduino/Teensy/Whatever Micro-controller DIY keyboard

fuzion_reaktor
fuzion_reaktor over 11 years ago

Hello element 14, I am seeking the advice of whomever may offer it on how to make a DIY keyboard using, preferably an arduino pro mini, some other small type of arduino, or another type of micro-controller. Why I want to make a DIY keyboard you might ask? Reasons. Anyway, I need your help as all the websites and forums I have checked are either speculative, or deal with number-pads, not entire keyboards. There are no guides, nor much else I can find, and I'm not really into creating my own firmware with my current skill level. I plan to create my own PCB (not including the micro controller) and use hobby store micro momentary switches and generic diodes for this, along with whatever else you may suggest.

Anyway, thank you whomever can help me, and have a nice day.

    I've written up a conversion of an Acorn Electron into a USB keyboard on Instructables, here: Acorn Electron USB keyboard

     

    This uses a Freescale KL25Z dev board - see FRDM-KL25Z - FREESCALE SEMICONDUCTOR - ARM, KINETIS, KL25Z, FREEDOM DEV | Farnell UK - which is absolute overkill (48MHz Cortex-M0) for a keyboard scanner, but it has plenty of I/O and is super-cheap.

     

    You can browse the source for this here: https://mbed.org/users/IH/code/electron_kbd/ - the comment at the top of main.cpp has quite a bit of explanation as to how it works and how to customise it for other keyboard layouts.
