RobotC and ER4U arm/Robocell
Not sure if any of you have experience handshaking between VEX and an Intelitek ER4U. I am trying to run my VEX program started by a signal from the ER4U. I have a breadboard set up with an optoisolator to protect each circuit but I am unsure of how to incorporate the signal from the robot controller into VEX. I had it set up as a touch sensor so the robot should act as that, but RobotC doesn't see the the signal for some reason, meaning the value does not change when the program is running when looking down in the "sensors" dialog box after the output signal has been sent from the robot controller.
Any help would be greatly appreciated!
