AXIS with PyVCP Pause/Resume button
This minimal example shows how a pyvcp button can be added to AXIS, wired to a toggle component, then to toggle2nist (which I wrote back in 2008), and then to halui pause/resume. This makes the momentary-on pyvcp button pause the program when pressed once, and resume the program when pressed again.
The xml and hal files are here: pyvcp_pause_resume_button.tar
