Matrix Keyboard controlling LinuxCNC

i didn't know you are in China.
Do you manufacture these Keyboards?
I'll update you, if i tested the Code myself.

I come from a manufacturer of CNC lathes in China, this is the panel is our supplier's product, because I think the price is low (about 600 yuan), so I want to try it.

For me, LinuxCNC is nothing short of torture, and it's good to have you kind people.

Thank you again

Hi,
so i found a bug, that might have prevented it from working for you.
I also updated it to Github.
I've made it a 3x3 matrix and it works like this on my setup following the method above.

I was able to light up the LED as directed!!When I use a matrix key and a matrix keyboard separately, they both work fine.

But When I use my panel ，there are two problems,
1.when I open the keypad macro program, the LED blinking frequency starts to decrease.

2.Because keypad and multipleds share the rows, when I set the pins of the row to be the same, both keypad and multipleds don't seem to work properly, when I type M1:1, the whole column is lit, and when I press the key, it seems to be arranged vertically.

I noticed that both macros use the same variable name, is this caused by this. Or my wiring problem.

In any case, we are one step closer to success.

Thanks for the Feedback. I changed the Code a bit, so now the Pullup resistors from the Matrix Keyboard are disabled, while the LEDs are flashed.
I guess that could help.

Btw it should also work in LinuxCNC now. which Linux is your system running on?
