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'.
How to setup
Step 2: Upload programcode to the microcontroller (Here is the code to upload)
Step 3: Start Ozeki on your computer to try the keyboard
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.
