Question about matrix_kb

This is on a new machine, which poses new problems .
front panel This is the panel in question .
Some of these go directly to inputs on the cnc but some pas through a multiplexing board which not only takes inputs but has multiple outputs on the same strobe . It's an 8x5 configuration . The spindle and feed override and encoder go directly to the mesa cards .
The real issues now are how to get the matrix_kb component to work well with the PCB and how to get output lines from that component . The user thread is a 2ms right now . response on the keys is good .

Cheers

P.S. Today I found out that the component has shifted the inputs .
All buttons are in the corresponding row but in a new column .
I'll experiment with the thread speed .

I might be out of line here but seeing you are using Mesa cards, have you considered using the Mesa 7i73 Pendant Interface to drive your keyboard?

I preffer the 7i70 and 71/72 cards as they are 24v capable . And the 7i77 has good support for the MPG .

I'm curious ... have you solved with matrix_kb and your switch? How?

I tried running the thread slower but it got even worse . I think I'm going to use direct inputs on the 7i70 . It won't be too much hassle, but i'll get to that after i setup the toolchanger .

Cheers

matrix keyboard can be used in a couple of ways - you didn't mention how you are using it.
it can scan a matrix keyboard and convert to individual hal pins or
it can read a scan code (usually from mesa 7i73 or panelui program) and convert it to individual hal pins.

I assume the first.
One problem is that matrix keyboards are momentary on buttons that share wiring.
A rotary switch always has at least one output closed.
This could bring in key roll-over problems.

I would suggest mux16 or mux_generic that have included debounce options for your rotary switch.

my 2 cents
