100KHZ PWM with 41.66% duty cycle

Using Arduino Programming Questions

Hi,
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);
}
}
