View Full Version : Wild motors while downloading

I didn't see this issue when I was writing my code as a single main() routine and linking with the easyC libraries, but now that I am implementing the methods in user_routines/user_routines_fast and linking with the Vex_alltimers.lib my robot begins to run the motors and servos randomly while the program is downloading. Once the program has completed its download, things are fine but while the download is taking place it has the nasty habit of driving the motorized arm into the chassis and then some. Could this be an initialization issue or a mismatch of library/firmware versions? If I don't figure this out I will have to unplug motors while downloading or this thing is going to tear itself apart.

Ok, I may have answered myself tonight. I realized that this was occuring when I started the robot when it was not connected to the serial port of the computer with radio off. When I connected the robot to the computer before turning it on, I found that there was no activity when I downloaded the program. Not sure if it is just a coincidence or not but it seems to be helping.

I remember this happened last year to us. We had one of the intelitek guys come over in between matches and we found that the CPU got damaged. We replaced it, and then it worked fine.
