Question description

#include "mbed.h"
PwmOut PwmPin (p22);
int main() {

PwmPin.period(0.000005);  // Set frequency to 200,000 Hz (period = 5 us)
  while(1){ //infinite loop
  PwmPin.write(0);  // Set the duty cycle to 0%
  wait_us(500); // wait 100 PWM cyles
  PwmPin.write(1);  // Set the duty cycle to 100%
  wait_us(500);  // wait 100 PWM cycles

Hi I'm working on mbed LPC1768. I have generated 1kHz square wave from 200 kHz wave using PwmOut (pin22).

I need to convert that square wave into sine wave but i don't know how to do it.

Please help me.

Thank you
