Matrix_kb 7i73 need help

key8 key9 key10 key11 = 3.26v
key12 key13 key14 key15 = 4.2V (key12 It works by itself sometimes.)
 
 

it works now I'm using hot air with RN7 all the input is 3.3v power.
I can watch 4x8 from halshow but still can't set the halfile.

Are you saying that there was a hardware problem that is now fixed, but that you still need help with the HAL configuration?

How far have you got wth the HAL?

If you watch the keycode pin in HAL, does it appear to be showing key-up and key-down events?

That's right, the hardware works.
I can watch the keycode pin in HAL.
but when i connect to jogging it does not respond

Please show an example HAL?

This is just from memory

[/code]
loadrt matrix_kb config=8x8
addf matrix_kb.0 servo-thread
net hm2_.....7i73.00.scancode => matrix_kb.0.keycode
[/code]

At that point you should be able to see one of the output pins toggling on and off when you press the key.

Can you confirm that that part works? (halshow is the easiest way to monitor a lot of pins.

Thanks, I'll test it when 7i92 works.

I have tried to use the parameter matrix_kb.0.negative-logic 0 of matrix_kb, but it always gives me an error saying that it does not exist.

    I I have problems with the configuration of the component matrix_kb. I am going to use the Matrix_kb and SENDKEYS components simultaneously. For that, I configured the 7i73 for a 4x8 keypad with the SENDKEYS component, and for the Matrix_kb component I configured it 3x4, for this I used some of the 7i73's available outputs and inputs. The problem now is that I get the error "kb_3x4.row-00-out does not exist" ie. Another error that I get is net zero-x halui.mdi_command-00 not found despite being defined in the INI file. I attach my files.

It should be there:  github.com/LinuxCNC/linuxcnc/blob/master...nts/matrix_kb.c#L311
Note that as a parameter you can only "setp" it, not link it. 

Possibly you are trying to "setp" the value before the component has loaded?
