We did last year, and a couple years before that. We had "feet" on our robot that were pneumatically activated to make the robot unmoveable. The button on the control panel toggled their state. Pressing it while they were down would raise them, or lower them if they were up.

I've never come across the problem where the signal would bounce. I'm not sure if thats something IFI compensated for, or if it just hasn't been a problem yet.


Windward: If you use the code that I gave you, the "char oldstate" has to be defined either globally or staticly. Either put it at the top of the code, above any function, or use "static char oldstate;" instead of "char oldstate". That code should go below the default relay stuff, otherwise they will override it.
