Remapping Your Keypad

Windows

If you are on Windows 8.1 or lower and you haven’t already, follow the driver installation guide first.

Driver Installation

Once the drivers are installed, download and extract Termite. You want to make sure you extract since you need to run it with the .ini file in the same directory.

Download Termite

Upon opening the program, it should immediately connect to the keypad. Follow the directions in the remapper and you’re all set!

  • If you have any problems, make sure your settings match these (except for the port since it may be different for you):

Make sure to close Termite when you’re done, otherwise it may try to reconnect and lock up your keypad.

Universal

You can also use the Serial Monitor included in the Arduino IDE. This can be done by downloading the IDE through the Arduino website here:

Download

Follow the wizard for installation and launch the program. From here you can select the port from Tools > Ports and open the Serial Monitor by clicking the magnifying glass icon in the top right of the window.

Warning

Make sure you change “Newline” to “No line ending” in the bottom right of the serial monitor or the keypad will think you’re trying to map every key to a newline character.

Mac and Linux (if you don’t want to install the Arduino IDE)

The procedure for Mac and Linux is the same since we’ll be using the screen command on both. As we do on windows, you’ll first need to find the serial port of the keypad. You can do so by entering this into the terminal:

dmesg | grep tty

If you just plugged the keypad in, it should be the last thing listed. In my case it’s using /dev/ttyACM0. Now we can start serial communications using screen.

screen /dev/ttyACM0 9600

That’s it!
