说明：  51单片机资料及程序需者请下载好东西教材类(51 Single-chip data and procedures, please download good teaching category)

PWM调光,通过PWM（脉宽调制）调节LED的亮度(PWM dimming to adjust the brightness of the LED by PWM (Pulse Width Modulation))

此文档，主要是实现开发板显示中文，用到了locale与busybox,(This document, mainly to achieve the development board display Chinese, use the locale and busybox,)

假设P1.0口为发光二极管（共阴），其通过按键来控制是否开启(Suppose that the P1.0 port is a light emitting diode (common negative), which controls whether to turn on or not by pressing a button.)

说明：  超声波传感器数据采集，arduino实现。并在道路检测中使用(The data acquisition of ultrasonic sensor is realized by Arduino. And it is used in road detection)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )
