How can i create square wave signal in C for pic micros?

Regards.
 

Hi,

it's so easy
for example to creat 1khz square wave using ccs c compiler.

We calcualte time duration T=1/1000Hz = 1 ms
Then divide it by 2 ---> 1ms/2 = 500 us

while (1) {
output_high(PIN_A1);
delay_us(500);
output_low(PIN_A1);
delay_us(500);

}

Bye
 

Also, many controllers have timers with PWM output. Then you have to program timer to generate PWM with 50% duty cycle and frequency 1kHz....
 

You can use PWM or timer to create square wave ,it may just frequency your need. :)
