hostmot2 oneshot bitfile help was created by roland

I would like to use hostmot2 oneshot.
linuxcnc.org/docs/2.9/html/man/man9/hostmot2.9.html#oneshot

To build the bitfile I have to edit my *.vhd file.
But I don't know how to modify the file for oneshot.

My configuration consists of 7i92 + 7i76 + 7i85S

One smart-serial on the 7i76 and the encoder on the 7i76 are not needed.

Attached is my existing .vhd file

The Oneshot module has an input (trigger) and two output pins
what pins do you need (0 to 3) and where do they go?

I am detecting very short signals from a laser light barrier.
For this I need one hardware input (trigger).
The signal should then be linked with probe-in.

The use of hardware output pins is not planned.

So actually the one input is enough for me.

Here's my test pinout (for a 7I96S) You should be able to copy/paste from it

I forgot that the oneshot can actually have up to 4 pins (2 inputs and 2 outputs)

Process "Generate Programming File" completed successfully

I look forward to test this on the machine in the next few days.
Thanks for your support

But LinuxCNC does not create the oneshop pins

I'm on latest buildbot master LINUXCNC - 2.10.0-pre0-272-g10db23f49

Any ideas?

Look like there's a bug in the command line parsing
Try without the num_oneshots stanza in the command line
