在端口PD输出PWM脉冲,可用示波器测量,或者外加一LED灯，可以看到LED脉宽的变化-PD PWM pulse output port can be used oscilloscope or plus an LED light, you can see the LED pulse width changes

In this archive is included an example code in proton basic compiler how to implement PWM using interrupt.It is used for regulating light intensity of led diode depending on light ambient.When the light is low led diode is full powered and light inte

PROTEUS isis led light

能够实现LED的控制，有8种点亮模式,运用GCC（win-AVR）编译器进行Atmega16L单片机的编程-if you need 8 ways of making the LED lighting, and you will need the program with GCC(win-AVR)
