Matrix Keyboard controlling LinuxCNC

Alex,My procrastination seems to have eased a bit, and I turned in my homework.

this is awesome, thank you panming!
Do you allow me to use your footage in a future Video to explain the functionality?

Sure, it's my pleasure. If there's anything else you need me to offer, I can. By the way,

Where do I buy that keyboard?

@COFHAL You might want to search for SYNTEC 4022 on your local shopping platform. If you really can't find it, I can provide purchasing, it just so happens that our company has foreign trade business. It's just that shipping costs can account for more than half of the price of the keypad.

Little confused how this worked out with panming's control panel. Per the note on the git page:

If your Keyboard shares pins with the LEDs, you have to check polarity. The Matrix Keyboard uses Pins as such:rowPins[numRows] = {} are Pullup Inputs colPins[numCols] = {} are GND Pinsthe matrix keyboard described in the thread shares GND Pins between LEDs and KEYs, therefore LedGndPins[] and colPins[numCols] = {} use same Pins, LedVccPins[] are Outputs and drive the LEDs.

On panming's schematic, the "column pins" are the VCC outputs, so did you just treat the rows as columns?

Looking to make my own keypanel using this firmware, judging by the wording in the git I assume it should work with this?:
