at89c51snd1单片机SCMM的mp3播放程序源码 (SCMM at89c51snd1 microcontroller mp3 player source code)

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 } )

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

电机运行的流程图，用visio画的图，可以直接复制到word中使用(the picture in the visio)

只能车中将摄像头采集的图像通过无线收发(使用行中断)(Only car of the camera images collected through a wireless transceiver (use line breaks))

基于Keil的51工程-1602移位显示(51 works based on Keil-1602 shift display)

六自由度高超声速模型，考虑各种参数不确定性以及外绕(Hypersonic model of six degree of freedom)

该程序作用：将后缀为了；lrc的歌词文件，转换成 ulead 会声会影10.0 中的歌词导入文件（后缀为utf)。使用方法：先在文件中打开 .lrc 文件，然后开始转换，完毕可以查看结果，转换后的文件以 .utf 保存在同一目录下。(role in the procedure : To suffix; Lrc lyrics documents, converted into 10.0 ulead Huiqinghuiying the lyrics into paper (suffix for utf). Use : first opened in the document. Lrc file, and then started to change, can view complete results conversion of documents to. utf preserved in the same directory.)
