[FVC]: MPLab using two transmitters

Okay, I looked and looked and can't find example code to do the following: One transmitter drives the bot. The other transmitter handles the arm and servos. I see how to do it with EasyC, but how do you do it in MPLab. Do I have access to two RxData/TxData data structures. Where?

Quote:

/*
* Driver Control - Rx1 preferably
* pwm03 - left side drive
* pwm04 - right side drive (reverse it)
*
* Arm Control - Rx2 preferably
* pwm01 - Arm raise/lower
* pwm02 - Arm extend/retract
* pwm05 - Servo to lock arm
*
*/

Thank you!

Re: [FVC]: MPLab using two transmitters

PWM_in1 through 6 are from the first Vex receiver port
PWM_in7 through 12 are from the second Vex receiver port.

So...

Code:

// Driver Control - Rx1 preferably

  pwm03 = PWM_in1;  // Depends on what mode you select on the transmitter

pwm04 = PWM_in2;



//Arm Control - Rx2 preferably

pwm01 = PWM_in7; //- Arm raise/lower (on CH 1 of 2nd transmitter)

pwm02 = PWM_in9; //- Arm extend/retract (on CH 3 of 2nd transmitter)

pwm05 = PWM_in11; //- Servo to lock arm (on CH 5 of 2nd transmitter)

In ifi_aliases.h you'll see them:

Code:

 *  Below are aliases for the PWM inputs received from the radio-control receiver.

Mark:

Thank you. Thank you. I knew that. I just had a brain freeze these past three days trying to get ready for the tournament that I'm running on 2/24 (Georgia FVC) and mentoring my team at the same time.

I coded it right after I got your reply and it worked like a charm. Chimera #832 thanks you very much.
