Which pin should I connect pwm output to in pic18f452?

[s13v3n]

i have a pwm output and want to connect to a pic microcontroler.which pin should i connet to?

pic18f452 pwm on port

if u r using PIC BASIC compiler or proton plus compiler u can connect it to any pin

pwm pic18f452

i am using 18f452 PIC microcontroller

pwm with pic18f

what is that you want the pic to do with that pwm?

pwm com pic18f452

i want to measure the speed of the vehicle.so i need to use the pwm output to measure the distance travel and from the distance obtain i want to calculate the speed of the car.

pwm pin for pic18f452

then you can give it to any of the port pin,
try avoiding portA. Port B should be the best

18f452 pwn

do u know anywhere i can get some example of source code?

Hi do you manage to get example of source code?

Re: pwm to pic18f452

Hi,
Here is a sample code:

//Program to generate 40kHz output at RC2(CCP1) pin
//Microcontroller: Microchip PIC18452
//Language: C
//Compiler: mikroC v8.20
//Programmer: Tahmid

void main (void){
     TRISC = 0;
     PORTC = 0;
     ADCON1 = 7;
     T2CON = 0;
     TMR2 = 0;
     PWM1_Init(40000); //40kHz
//The value in brackets in PMW1_Init represents the frequency in Hz
     PWM1_Change_Duty(128); //50% duty cycle
// Choose Duty cycle as such:
// PWM_Change_Duty(x);
// x = ( (Duty Cycle in %) / 100) * 255
     PWM1_Start(); //Start PWM
     while (1){ //Loop forever
// Whatever else might be needed to be done while PWM is running
     }
}

If you want to use hardware PWM then you can use RC1 (CCP2) or RC2 ( CCP1) as PWM output, but you can get the same frequency (PWM) output if you use both
