1 of 3 to output // 7i73 MPG not functioning

forum.linuxcnc.org/24-hal-components/332...of-3-to-output#98841

I tink your answer lies here linuxcnc.org/docs/html/man/man9/logic.9.html

There is also an example in my HAL of a flashing light Todd wrote which is also documented in my build thread. I seem to remember that siggen outputs a float and you need a bit to trigger an output. There is no float to bit conversion so you need to convert the float to s32 and then convert from s32 to bit. A siggen squarewave should alternate from 0 to 1 in this way.

Will certainly have a look at LUT5 but first I need to get MPG+switches working.

Hopefully Peter will chime in here and have a look why the PNCCONF generated code 7i73 related MPG is not working.

Here my latest HAL and INI


Switches verified working OK, MPG Counts.

So something is missing.

My guess is that
means that for each step of the jog wheel you move exactly 0.0 machine units

Missed that one but still NO GO so something is not activated but what?

So what you are missing is a way to set the jog scale based on your switch position
It seems you are not using a binary coded switch as per this example
linuxcnc.org/docs/html/examples/mpg.html

Personally, I would replace your switch with the correct type and save one pin. Then you can follow the example above. Read it carefully and get to understand it fully, particularly how mux4 works. Follow the example I shared with you on my build thread.

If you follow "the rules" in the examples, life becomes much easier.....
Something like this which worked for me

This is what is in HAL for X-axis MPG, so what is missing

### MPG increment selector

# --- JOG-INCR-A X1 ---
net jog-incr-a <= hm2_7i76e.0.7i73.0.1.input-00

### MPG axis selector

# --- JOINT-SELECT-A Xaxis ---
net joint-select-a <= hm2_7i76e.0.7i73.0.1.input-06

# ---mpg signals---

# for axis x MPG
setp axis.0.jog-vel-mode 0
net selected-jog-incr => axis.0.jog-scale
net joint-select-a => axis.0.jog-enable
net joint-selected-count => axis.0.jog-counts

sets selected-jog-incr 1.000000


If I understand Peters message there is no need to have software MPG thus the code from PNCCONF should work.

Hmmm, I have found an orphan

loadrt mux16 names=jogincr

So something is missing here
