`ledcChangeFrequency()`用于设置引脚频率，`ledcOutputInvert()`用于设置反相输出，`ledcFade()`用于设置和启动淡入淡出，`ledcFadeWithInterrupt()`和`ledcFadeWithInterruptArg()`用于通过中断设置和启动淡入淡出。`analogWrite()`函数用于在引脚上写入模拟值（PWM波），兼容Arduino的analogWrite功能。`...
PWM frequency is 1kHz by default. CallanalogWriteFreq(new_frequency)to change the frequency. Timing and delays millis()andmicros()return the number of milliseconds and microseconds elapsed after reset, respectively. delay(ms)pauses the sketch for a given number of milliseconds and allows WiFi and ...
While playing with a couple of H-bridges one motor had more torque then the other. Although the voltage going to both motors was the same. The reason was that I was using 2 pins with different pwm frequencies. I had read that not all the pwm pins had the
调用analogWrite(pin, 0) 可以关闭引脚PWM。取值范围:0~ PWMRANGE,默认为1023。 PWM 范围可以使用analogWriteRange(new_range)语句来更改。PWM 默认频率:1KHz。使用analogWriteFreq(new_frequency) 可以更改频率。时间与延时 Timing and delaysmillis() 和 micros() 分别返回单位为毫秒和微秒的值,复位后值重置。delay...
PWM 默认频率:1KHz。使用analogWriteFreq(new_frequency) 可以更改频率。 时间与延时 Timing and delays millis() 和 micros() 分别返回单位为毫秒和微秒的值,复位后值重置。 delay(ms) 暂时程序给定毫秒时间并允许WiFi和TCP/IP任务的运行。delayMicroseconds(us) 暂时程序给定微秒时间。
