My code currently is reading the falling edge of a rotary encoder and works good but how do I include the rising edge aslo in the code to improve accuracy?
Could you give me an idea on how to include the rising edge in my code? Thanks,
Here is the Encoder part of the code
[code]
void throttleLoop() {
encoder_ThrottleUp = digitalRead(pin_ThrottleUp); // Read encoder pins
encoder_ThrottleDn = digitalRead(pin_ThrottleDn); // Read encoder pins
if((!encoder_ThrottleUp) && (encoder_ThrottleUp_prev)){
// A has gone from high to low
if(encoder_ThrottleDn) {
// B is high so clockwise
// increase the throttle, dont go over 220
if(servoPos + moveServoAmount <= 220) servoPos += moveServoAmount;
}
else {
// B is low so counter-clockwise
// decrease the throttle, dont go below 20
if(servoPos - moveServoAmount >= 20) servoPos -= moveServoAmount;
}
}
encoder_ThrottleUp_prev = encoder_ThrottleUp; // Store value of ThrottleUp for next time
// set the new location of servo:
throttleServo.write(servoPos);
}
[/code]
Here is the whole code.
