将PWM频率设置为25 kHz
我目前可以使用以下代码将四个PWM引脚设置为31 kHz左右: void setup() { TCCR1B = TCCR1B & B11111000 | B00000001; // Set PWM frequency for D9 & D10: pinMode(pwmPin9, OUTPUT); // Sets the pin as output pinMode(pwmPin10, OUTPUT); // Sets the pin as output TCCR2B = TCCR2B & B11111000 | B00000001; // Set PWM for D3 & D11 …
