All the digital pins on one of my 3 EZB V4's stopped working. I rebooted and reset the unit and still can't get the 3 volts at any of the digital pins when I try to turn them on through EZ Builder. I probably burned something up on the EZB but was wondering what type of mishap would cause them all to stop responding? I'm a little leary to just swap out the EZB with a replacement in fear that if I have a bad servo or transistor somewhere in the robot that it would damage the new EZB. Only thing I can remember doing is taking all the servo cables off the unit then reattaching them so I could reroute the wires and I also updated EZ Builder (after a year of not doing any updates). After checking all cables they are plugged in right and I don't recall plugging any in backwards and having to correct it.
I do remember thinking after doing the update after a year of not doing them how much smoother and faster servos were responding now, so I did have digital control for a while after the update. *sick*
