AVR MCU PWM generation-EEWORLD

Collect

The upper limit of the counter determines the frequency of the PWM, and the value of the compare match register determines the duty cycle.

The following is an example of using t0 to generate PWM

PORTA=0XFF;
PORTB=0X00;
TIMSK=0X00;
TCNT0=0;
OCR0=240;
TCCR0=0B01101001;

while(1);

Several advantages of using PWM technology in inverters

　　The pulse width modulation technology PWM of the inverter is a kind of technology that uses a reference wave as the "modulation wave" and a sine wave with a frequency N times that of the modulation wave as the "carrier wave". Since the upper and lower widths of the sine wave or sawtooth wave are linearly changing wa

Based on STC15L104E single chip microcomputer simulation PWM dimming night light

Since the lights in the dormitory would be turned off by the dormitory manager at night, I made a small table lamp to "spy" after turning off the lights. However, my roommate Chen said that the light was too strong and affected his sleep, so I decided to make a dimmable LED night light to spy on my privacy and let othe
