About Arduino Fast PWM Calculator:
This free calculator helps determine PWM register values and timing for Arduino microcontrollers using Fast PWM mode.
PWM Calculation Method:
- PWM Frequency = F_CPU / (N × 256)
- OCR0A Value = (256 × Duty Cycle) / 100 - 1
- Where:
- F_CPU = CPU frequency
- N = Prescaler value
- 256 = Timer resolution (8-bit)
- Duty Cycle in percentage
Code Example:
#ifndef F_CPU
#define F_CPU 8000000UL
#endif
#include <avr/io.h>
int main()
{
DDRD |= (1<<PD6); //Fast PWM output at OC0A pin
OCR0A = 191; // Duty cycle of 75%
TCCR0A |= (1<<COM0A1) | (1<<WGM01) | (1<<WGM00); //Non-Inverting Fast PWM mode 3 using OCR A unit
TCCR0B |= (1<<CS00); //No-Prescalar
while (1);
return 0;
}
