Matrix Keyboard controlling LinuxCNC

i forgot: you have to set the Serial Monitor to 115200 Baud to connect.

hello，Alex，I'm happy that I can get yor reply just after waking up.I read the code and it seems to work. Looking at your code, I realized that I had complicated things before, and it seems that your method is much easier to understand.

I will test it on the machine as soon as possible.

Alex,I'm sorry that I forgot my ssd is breaken.I will test tomorrow.

Alex,sorry to be late.I tried your program and it doesn't seem to be working correctly.

I'm not sure if it's due to a pinout error in the panel.

to simplify things ,I replaced it with a regular 8*8 matrix keypad.

When I type M5:1 all the led light up at the same time, and type M5:0 the led still work.

Even when I uncommented the delay function that you commented out, the situation remains the same.

Looking at the debug message, it seems that the packet is correct.

are you shure you didn't invert the polarity of the LEDs?

It seems that there is indeed a problem with the polarity, but even if there is a problem with the polarity, when I type M5:1, he should turn off the led5.

I'll be going to really analyze what the problem is on Sunday. I still have to go to work on Saturday.

Ok, i will too work on it and try to test the code myself.
Do you use Discord? Maybe we can have a video Chat?

Sorry, due to the special network environment in China, we can't use most foreign instant messaging platforms, my VPN's bandwidth may not support real-time video, maybe we can use other methods, TG or WeChat

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
