Simple LED Question was created by rjshust
My first post here, so please be gentle.
I recently finished up my cnc router (call it a blacktoe clone) for hobby work, and I have been busy playing with it.
I am now trying to figure out PyVCP with some success. I have buttons to jog the axis, go home, router/spindle power on/off.
I want to have an LED to show if the power is on or off to the router (pin 14 on my setup), but for some reason I am having no luck. I have built the LED in the panel, and given it a halpin name. I assume my problem is with the postgui.hal, but I don't know that for sure.
First question, do you think this is a problem with the postgui.hal, or am I on a wild goose chase?
Second question, if this is a problem with postgui.hal, then could someone give me a code example on how to wire this LED up?
Thanks for any ideas given,
Rob

Hi
You will need to post your hal files and your xml file for the panel.
We cannot guess what is in them.

You have the line net spindle-on => pypvc.Pin-14 in the post gui hal file commented out so it will never work.
If you open up the Show Hal Configuration you can see the status of pins and signals.

looks like you spelled the pin wrong :
pyvcp.Pin-14 not pypvc

Thank you - Thank you - Thank you
I feel so stupid.
I spent hours trying to figure out how I was wiring it up wrong, and it was just a spelling error.

Follow up question.
Is it possible to alternate between 2 images instead of 2 color for the on/off? If yes, could I get a quick code snippet?
I have no problem displaying a single image
I just don't know how to alternate between of/off like we do for colors

Yes it is possible, but a bit different. In fact it is possible to choose between multiple images. It has been quite a while since I did it my self (can't remember it all). Tomorrow I'll post a copy of the config I set up. It has 8 windows that describe the state of the 8 VFDs on an 8 spindle gang router. The indecators are different color boxes with text saying things like "RUN", "STOP", "FAULT", "ACCEL", "DECEL"...
