	pwm_02 = 220;
	if (rc_dig_in06 == 1)
	encoder = encoder + 1;
	if (encoder == 11)
	pwm_02 = 128;

You only want to increment the encoder variable when rc_dig_in06 goes from 0-1 or from 1-0 (pick one). So you need to keep track of the previous value and the current value, then increment only when when it changes.
