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?

It still looks like something is wrong, when I set LedGndPins and rowPins to be the same and send M1:1,  the panel looks like this(first attachment)
The number is the name I gave them, if normal he should be numbered this way. After the number is the feedback value of the button, the green unit represents the LED flashing, and the red represents normal brightness.

when I set LedGndPins and colPins to be the same and send M1:1,  the panel looks like this(second attachment )I don't know what causes it, which two arrays should I set to be the same. Or do I have a problem wiring.

can you please post the settings you use in the second configuration?

The rowPins are Pullup Inputs, so they should not be used twice.
The ColPins are GND Pins for the Matrix Keyboard and the LEDs.
so set colPins und ledGndPins to be the Out0-8 Pins.

When you wire it like this and send M1:1 the all red numbers light up simultaneously?

yes,Yes, they lit up at the same time. And, when I type M1:0, they don't turn off, but when I type M2:1, several LEDs of M1 turn off.At the same time the third column began to light up, i.e. 2, 10, 18...

get the latest Code from Github.
It works in my test.

Also i think you misunderstand the use of the command.
the Number after M represents one LED. So looking at your table, each Number is one LED and can be written by one M code.
So only type M0:1 it should only turn on LED 0. (top left corner).
Also the way your keyboard is wired, i think it might be numbered differently.

ive changed the code to cycle through all the LEDs once / loop, therefore it should work better now, without the flashing.

To prevent misunderstandings caused by translation software, I uploaded a video on YouTube.
