PWM-control-LED-brightness
- 在单片机中通过PWM控制led亮度,包括四种控制情况:1、第1,3,5,7个灯半亮,其余的全亮。 2、第1个亮1/8,第2个亮2/8,第3个亮3/8,第4个亮4/8,第5个亮5/8,第6个亮6/8,第7个亮7/8,第8个全亮。 3、所有的灯逐渐从暗到全亮,再由全亮到暗。 4、8个灯从第一个开始依次渐亮,直到最后一个。再从最后一个起渐暗,直到第一个。如此循环往复。 -PWM control LED brightness in Microcontroller
PWM
- 2.单片机中的PWM 指的是此单片机有部分I/O口具有输出PWM信号的功能。 比如说部分单片机的I/O口可以输出时钟信号,时钟信号的脉宽和占空皮可调,可以根据实际需要调整寄存器位来设定。 3.基本思想就是利用单片机具有的PWM端口,在不改变PWM方波周期的前提下,通过软件的方法调整单片机的PWM控制寄存器来调整PWM的占空比,从而控制充电电流。以此来调整亮度 -basic principle refers to apply PWM port
