No Output On Channel 4-7

Posted by Dean Lamborn on December 3, 2010 at 4:38pm
Everything work ok otherwise. The 4 motors run correctly, the sensors all check out.

I have a Corona digital servo that works when I plug it into the receiver or output channel 0.

On output channel 4-7 I don't get anything.

servoMotor = constrain(APM_RC.InputCh(3), 1220, 1780);

APM_RC.OutputCh(6, servoMotor);

APM_RC.Force_Out6_Out7();

I put the variables in the serial monitor. Input channel 3 and servoMotor goes from 1220 to 1780.

The only time the servo reacts is when I plug in the power. It twitches once.

Power is from the LIPO through a BEC plugged into output channel 7. The red wire to the four ESC's are disconnected.

    Thank you Sebastian. All four outputs are tied to digitalWrite for LED's with isAM.

    The servo works with #define IsAM commented.
