I tried a code to obtain 100KHZ PWM output with 41.66% duty cycle by reading an analog value at A0 which is compared with a reference 5V value for obtaining PWM value.

Can some one help me with the code? Any help is very much appreciated.

here is my code.

  int Pwmpin=9;//Pwm Output Pin
  int Fchange= A0;//Frequency change through Potentiometer
  void setup()
  {
  pinMode(Pwmpin, OUTPUT);//Pwm pin as Output
  Serial.begin(9600);
  TCCR1A=_BV(COM1A1)|_BV(COM1B1);//Non-inverted Mode
  TCCR1B=_BV(WGM13)|_BV(CS11);//Prescalar 8
  }

  void loop(){
  float freq=0;
  float count=10000,countt=0,Pinput=0;
 
 while(1){
 ICR1=count;//variable Frequency
 countt=16*count;
 freq= int(16000000/countt);
 OCR1A=int(count/2);
 Serial.print("Pwm Freq =");
 Serial.println(freq);
 count=10000;
 Pinput=analogRead(A0);//Read input value
 Serial.print("adc value is:");
 Serial.println(Pinput);
 Pinput=(Pinput/0.0113);
 Serial.print("pwm value is:");
 Serial.println(Pinput);
 count=count+Pinput;
 if(count>=100000)
  {
    count=10000;
 }
    delay(1000);
  }
 }
