Keyboard Controller connection

Keyboard controller connections guarantee that all of the pressed keys are forwarded to a selected connection in your Ozeki software. The supported MPR121 capacitive touch keypad has 12 buttons, which are numbers from 0 to 9 plus * and #. For the proper wiring diagrams you can check the supported boards below in 'Step 1'.

Prerequisites:

  • MPR121 capacitive keyboard
  • Ozeki 10 installed on your computer
  • Programmable board (Arduino Mega/Nano/Uno, Ozeki Display Modul or Raspberry Pi)
  • USB cable is needed between Arduino Mega/Nano/Uno, Ozeki Display Modul and your computer

How to setup

Step 1: You can see how to wire the MPR121 capacitive keyboard
to any of the following boards:
Start the video
After wiring, please plug the board to your computer!

Step 2: Upload programcode to the microcontroller (Here is the code to upload)
Start the video

Step 3: Start Ozeki on your computer to try the keyboard
Start the video

If Ozeki 10 is running on your computer (such as on a Raspberry Pi) and you have plugged a microcontroller to it than Ozeki can be set to find serial devices on windows/linux and place them into a connection list so you can interact and control them through the software GUI. The Keyboard Controller can communicate with Ozeki through the following protocol.
