I m doing a PID tuning. First I defined constant error and try to tune the PID. I input the angle of 40 degrees and got the difference between encoder reading angle and 40 degrees as error in my program. I want to ensure my encorder pulses reading is correct or not, and if not please help me. I used RB4-7 interrupts.
I use MikroC language, PIC 16f877, Pololu Encoder motor.
encoder motor information. It gives 64 pulses per one "motor revolution" and gear ratio is 50:1. Then it gives 3200 pulses per one revolution of "gear box shaft".
Pololu - 50:1 Metal Gearmotor 37Dx54L mm with 64 CPR Encoder
Please help me
Here is my encoder reading code
If you are not clear i'll post whole code. So please help me.

Here is my encoder reading code
Code:
void interrupt ()
{
if(portb.f7==1) //if channel A start first cnt add
{
cnt++;
}
if(portb.f6==1) //if channel B start first cnt decreace
{
cnt--;
}
INTCON.f2=0;
intcon.f1=0;
intcon.f0=0;
}If you are not clear i'll post whole code. So please help me.
