7. Pulse Width Modulation脉宽调节(PWM)是获取数字引脚上人工模拟输出的一种方式。其通过引脚从低到高的迅速切换实现其功能。有两个与此相关的参数:切换的频率和占空比。占空比定义为高电平的时长占单一周期的比率。始终处于高电平时,占空比取最大值,始终处于低电平时占空比最小。

Pulse-width modulation (PWM) is a technique that modifies the duty-cycle of a pulsing signal to encode information or to control the amount of energy provided to a charge. On the ConnectCore 8M Mini system-on-module: Four PWM signals (from PWM1 to PWM4) are available from the {cpu-...
二进制特性:PWM信号本质上是一种二进制信号,它只有两种状态:“高”和“低”。 占空比:PWM信号的关键参数是占空比(Duty Cycle),它定义了在一个周期内信号处于高电平的时间与整个周期时间的比例。例如,如果…
CHAPTER 9 Pulse-Width Modulation This chapter explores pulse-width modulation (PWM) using the Raspberry Pi. PWM is applied in motor control, light dimming, and servo controls, to name a few examples. To keep the hardware simple and the software small enough to read, we’re going to apply ...
