RC Analog Pins not working

[Al Skierkiewicz]

We found a few 2008 RC loaded with Version 13 code in Chicago. If your code cannot run on V13 then that might be the problem. To check, tether up and power the robot. Press the button underneath the team numbers on your OI to cycle through the readout and you will get to a display that starts with a v followed by two numbers. It should be v15 but if it is v13 you will have to reload the firmware and then your software. Just a possible solution...

I believe the rules say that if you are to use an '07 RC, it needs to be brought up to v15.

Can't find the quote though, so I could be wrong. I just seem to remember pulling out my '07 RC after reading that somewhere to upgrade it, just incase we ever needed to do a swap.

Make sure that there isn't a short between the red & black wires on any of the sensor inputs, or that all the lights are green; a low voltage output could cause the symptoms you're describing.

In all cases for us that the "analog pins stopped working" it was the case that there was an unintentional short between power and ground on the I/O pins. (We've had an embarrassing number of these occurrences over the past four years!) An important thing to note is that the short doesn't need to be on the analog pins! We had a problem this year where a short on some unused digital I/O pins made itself apparent only because the "analog pins stopped working."

The rules say master code v15 must be used (regardless of the controller year) and Team Update #11 allows teams to use 2007 controllers.

All,
If you have a 2007 controller and it was used on an FRC robot after week 1 or 2 last year, it should have been upgraded to v15 at or before those events. v15 was introduced last year and was checked as part of the inspection process. v15 is dated 2/27/2007.

It's actually a u followed by three numbers (the version number intrudes briefly on the "user mode byte" display). The inspectors expect to see u015 when they check.

thanks for the help guys. i guess ill be doing a bit more debugging tomorrow.
