No PMW output in Autonomous
I'm having a problem communicating with the motors in Autonomous Mode. The motors work fine in the Default_Routine. When the RC is in Autonomous (the RC mode light is blinking yellow), the indicator LED's on the Victor 884's blink yellow, meaning there is no PWM input to them. In the Autonomous code, I've got the pwm variables assigned like I want them right before the Putdata(&txdata) statement, but the information is apparently not being output.
Is there some trick to driving motors in Autonomous? Or is my system configured incorrectly? The RC is disconnected from the OI (no tether), after the team number was set to 0000. That should work, shouldn't it, or do you have to have a competition dongle? Thanks in advance for any advice Russell Clothier, Team 1723 |

Re: No PMW output in Autonomous
You need a dongle, ( You mean the competition port switch...right?) to run autonomous.
http://www.ifirobotics.com/docs/comp...guide-reva.pdf See... switch 2 Um... you DO have the radio link up...? Without a radio link or thether, the robot won't do anything,,, it's a safety setup. Steve (Or are you talking about something else and I'm just being stupid? (An after thought) if you're using PWN13-16... your statements should be before the Generate PWMs Last edited by Steve_Alaniz : 24-01-2008 at 18:34. Reason: Another thought |

Re: No PMW output in Autonomous
Not true. The setup that Russell is describing (tether, set team number to 0000, untether) is another way to set the RC into autonomous mode. (Steve, see page 10 of the RC reference guide.)

Re: No PMW output in Autonomous
I'll be darned. Not sure why you'd want the option of going into autonomous with all of your motors disabled, but that certainly explains my problem. Thanks!

Re: No PMW output in Autonomous
My take on this is that it's a safety measure. With team number set to 0, no tether, and no radio link, there's no way to stop an ill-behaved (or polite, for that matter) robot other than chase it and turn off power somehow. And, as soon as the program is downloaded, it'll take off, with the program cable still attached.
