PWM 能在所有可输出引脚上实现。基频的范围可以从 1Hz 到 40MHz 但需要权衡: 随着基频的 增加 占空分辨率 下降. 详情请参阅: LED Control. Use the machine.PWM class: frommachineimportPin,PWM pwm0=PWM(Pin(0))# create PWM object from a pinfreq=pwm0.freq()# get current frequency (default 5kHz...

$Spindle/PWM/Frequency 或 $33 - 主轴 PWM 频率(扩展设置) 这是主轴/激光 PWM 的频率。必须重启 ESP32 才能生效。 $Spindle/PWM/Off 或 $34 - Spindle PWM Off(扩展设置) 这是以百分比表示的 PWM 关闭值。这通常保留为默认值 0。它用于 ESC 类型的主轴以保持脉冲处于关闭状态以保持 ESC 正常运行。
LED PWM 控制器 API 会在设定的频率和占空比分辨率超过 LED PWM 控制器硬件范围时报错。例如,试图将频率设置为 20 MHz、占空比分辨率设置为 3 位时,串行端口监视器上会报告如下错误: E (196) ledc: requested frequency and duty resolution cannot be achieved, try reducing freq_hz or duty_resolution. div_...
The pin I’ll be using a PWM pin is GPIO5 in this example. Then, we’ll be configuring the PWM Channel’s frequency & resolution. And in the main loop() function, I’ll be gradually increasing the PWM’s duty cycle to max value, and gradually decreasing it to the minimum value, ...
