HI all
I am working on rc servo with dspic30f4011. I am trying to run rc servo with outcompare unit. But it's not working.
software: micro c pro for dspic
code:

void main() {
TRISD= 0x00;
PORTD.B1=1;
TMR2=0x00;
OC1CON=0x0000;
delay_ms(10);
OC1CON=0x0005; // timer 2 is selected
PR2 = 624;
OC1R=200;
OC1RS = 312;

T2CONbits.TON = 0; // Disable Timer
T2CONbits.TCS=1; //external clock
IEC0bits.T2IE = 1; // disable Timer 2 interrupt
T2CONbits.TCKPS = 0b11; // Select 1:256 Prescaler
T2CONbits.TGATE = 0; // Disable Gated Timer mode
T2CONbits.TON = 1; // Start Timer
while(1) asm nop;
}


need help...
THANK YOU.
 

What is your clock frequency of dsPIC30F?

Most RC Servos require a PWM period of 20ms and a duty cycle of 1ms to 2ms depending on the required position of the Servo.

Such low frequency PWM is difficult to achieve using the PWM module of the MCU.
