7i76e: MPG and Analog inputs with pncconf? was created by trilobyte
is it possible to set up the two MPG and the 4 Analog inputs of a 7i76e withe pncconf?
i wired my machine as shown in norberts connection sheet:
forum.linuxcnc.org/27-driver-boards/3191...-sheet?start=0#85072
id like to use one mpg for the x axis and the other for the z axis of my cnc lathe.
The potentiometers should be connected with feed and spindle override etc.
is this possible with pncconf?

I don't think so.
pncconf is just to get you going. The Mesa ecosystem is so rich, it simply can't do everything. Its time to get your hands dirty and learn how to hand edit hal files.
If yo have a look on my spaceship plasma build, forum.linuxcnc.org/show-your-stuff/32029...-plasma-cutter-build there is a complete worked example on how to use a MPG on a 7i76e.
As far as the analog inputs go, I have only had a quick play but the pin value is the voltage on the pin. Just patch it to your 24 volt power and use halshow to view the results and you will get your head around it pretty quickly.

pncconf can configure 7i76e in mode 2 which allows two MPGs and analog inputs.
Select mode 2 on the I/O connector 1.
There is no way to configure the analog inputs in pncconf.
You can do that manually in one of the HAL files.

Try changing to
sserial_port_0=2xxxx

I tried this in the latest version of pncconf in the 2.7 branch - what version of linuxcnc are you using?
it has to do with the selection of external MPG, on the external controls page. What option did you select and what di you select for the MPG encoder in the mesa page?

if i select this mode 2 pncconf crashes when i try to safe and quit:

i'm using the latest master 2.8xxx
i tryed different options in the external controls page. if i set the mode 2 in the I/O connector 1will crash if i try to finish the pnccconf.
i get 3 potentiometers running. i found some code from a 2.7 installation. the first 3 blocks are running after smal changes.
but for the jog speed this looks different. can someone help me with the fourth block of code? the one vor the jog speed.

This assumes that you use 1 MPG for all axes and you use a binary coded selection switch so you only use two inputs to set 4 sale settings one of them is 0 or OFF. The order of the mux4.in's is dependent on my hardware but it is a metric machine so in mm.
loadrt mux4 count=1
addf mux4.0 servo-thread
# Scale Select
setp mux4.0.in0 0.0
setp mux4.0.in1 1.0
setp mux4.0.in2 0.01
setp mux4.0.in3 0.1
net mux4-sel1 <= hm2_7i76e.0.7i76.0.0.input-22
net mux4-sel0 <= hm2_7i76e.0.7i76.0.0.input-21
net mux4-sel1 => mux4.0.sel1
net mux4-sel0 => mux4.0.sel0
net jog-scale <= mux4.0.out
net jog-scale => axis.x.jog-scale
net jog-scale => axis.y.jog-scale

For completeness, I will add my axis selct code here. Normally you would use another mux4 component but in my case I have a 6 axis selection knob on my pendant so I've used a mux8 paired with a select8. This lets me add another 3 controls. eg. I could use the Axis 4 selection setting to control reverse run to step back and forth in the g code. (maybe....).
Also note you need to convert the data type to keep select8 happy.
Hope I've copied accross everything you need....
