Re: GTS Code

Here is another alternative to what usbcd36 said. We are not using quadrature encoders with our drive system but we are using a gear tooth sensor. The following code is what we used for one side to determine if we need to increment or decrement the counter.
Code:
if(pwm13 < 118)   
	{
		Encoder_3_Count -= ENCODER_3_TICK_DELTA;
	}
	else if (pwm13 > 136)
	{
		Encoder_3_Count += ENCODER_3_TICK_DELTA;
	}
What we are doing is looking at the PWM value for the drive on that side and if it is outside of a designated window we will then increment or decrement the counter based on the value of the PWM.
