Encoder Problemo

[meatmanek]

The encoders need to be plugged into digital inputs 1 through 6. Those digital inputs are interrupt pins, and without interrupts, kevin's code doesn't work.

Ithink that we are wired correctly

Do we have to call any function besides Encoder Initialization oroutside the readme?

Wouldn't you rather be certain that the wiring is correct? If you tell us exactly how it's connected, we can tell you if there's something you misunderstood about the wiring and need to change to make it work.

Here is a quick program I wipped up in easyC you can use to test your encoders.

Encoder 1 - Plug into I/O Port 1 (Channel A)
Plug into I/O Port 7 (Channel B)

Encoder 2 - Plug into I/O Port 2 (Channel A)
Plug into I/O Port 8 (Channel B)

Source:

void OperatorControl ( void )
{
      StartQuadEncoder ( 1 , 7 , 0 ) ;
      StartQuadEncoder ( 2 , 8 , 1 ) ;
      while ( 1 )
      {
            PrintToScreen ( "Encoder 1: %5ld   Encoder 2: %5ld\n" , (long)GetQuadEncoder ( 1 , 7 ), (long)GetQuadEncoder ( 2 , 8 ) ) ;
      }
}

Attached is pre compliled program incase you don't have easyC installed. You can upload it to your robot with IFI loader.
