Due to not having a touch screen and wanting a pendant &/or control that interacts with the toggle buttons on the touchy interface I've come up with these few snippets. I have no python experience, so I think I need some advice on the best way to attack this. Or am I barking up the wrong tree. The idea is to have a pendant closer to the machine or a control panel with buttons.
Create new halpins
Code:
self.c.newpin("select.fo", hal.HAL_BIT, hal.HAL_IN)
self.selectfo = 0
Logic for halpin, just sends and activate signal to the button callback
Code:
selectfo = self.c["select.fo"]
if selectfo and not self.selectfo:
wfo = wtree.get_widget("fo")
if wfo:
os = wfo.get_active()
if not os:
wfo.set_active(True)
self.selectfo = selectfo
So I can run touchy (in sim mode), use halcmd to send signals to the pins and the buttons seem to do their thing. There is a few changes in other areas I've had to make.
