Re: 706 had the curse of all curses
 

Have you tried loading the BuiltinDefaultCode robot example shipped with the CRio?
If that shows the problem, then it's obviously not the software.

Hi AL,
see post #13 of this thread. A new project was started using the default Linefollower code. In that code there is no teleop code. In this section the 2 lines were added, turn on 1 solenoid and wait 0.01. Along with these couple of lines, the init section was changed to add the solenoid in the initialization.

Running this code produced the same results, with the solenoid LED randomly turning off for brief periods when enabled.

Have you tried stategic placements of printf to determine if the code is leaving the OperatorControl() method possibly because the IsOperatorControl() occasionally becomes false?

Has the CRio flashing option included a reformating? (to get rid of any extraneous .out)

And because we have burned ourselves so many times by not keeping Windows->Preferences->FIRST Downloader Preferences properly up to date, we add:
printf("\n\n###################################### ####################");
printf("\n 2011 Astro Robot code version 2011_v1.0");
printf("\n Base Drivetrain #0");
printf("\n Build Date: %s at %s ", __DATE__, __TIME__);
printf("\n Clock Rate: %f /second",(double) sysClkRateGet());
printf("\n######################################## #################\n\n")

to the beginning of RobotIint(), just to be sure we know what we are running matches our intentions.

Pete,
Have you just tried simple code? Like just download the compressor code, nothing else, and see if it runs normally when enabled.

At 706, we have decided to go with redundant power to our radio. It seems the barrel jacks we had for our radio...one kit of parts and one from Andy Mark...possibly were both missed shipped and may have been 2.5mm instead of the specified 2.1mm. So we have replaced our barrel jack, but then not to take any chances we are also redundantly supplying the radio with power over passive PoE. We can remove either power source individually and our radio will not lose power.

Could you post a photo of the POE setup

Re: 706 had the curse of all curses
 

Not to be rude, but I actually think 1523 had the curse of all curses at Orlando a few weeks ago ;).

Your weekend sounds like a dream!

Best of luck to fixing your issues.

I'm not sure a photo will help too much as it's all buried in the guts of the robot now.

We split the Ethernet cable apart and the brown pair gets wired into the negative 12V terminal on the VRM and the blue pair gets wired into the positive terminal on the VRM. The VRM has 2 sets of 12V terminals, so we use one for the barrel jack and one for the PoE. The PoE cable is then patched from the RoboRio to the radio 12V Ethernet port...where the radio end gets the standard 4 pairs all coming in and the RoboRio end just has 2 pairs to carry just the data (on pins 1,2,3,6). So pins 4,5,7,8 at the radio are carrying the power.

Hope that helps.
