To use the loader, press the purple button on the left to open the .hex file you wish to load.
Next, press the button in the middle with the green arrow pointing downwards to load the file to
the keyboard. Finally, you can press the third button with the green arrow pointing to the right to
reboot the keyboard. [
NOTE
- you will have to unplug the Mathkeeb and plug it back in to turn it
back on]
You should now be able to use your mathkeeb with the newly loaded .hex file! If you are still
having trouble loading a custom hex to the keyboard, please see the PJRC website for help.
