单片机是一门实践性非常强的学科,为此我们突破传统思路,全面围绕单片机试验,从简单的流水灯开 始, 逐步的带领大家从这些简单的几行或者10 几行的程序,来熟悉和理解单片机的指令. -Single-chip is a very strong practical subjects, and we break through the traditional idea of a comprehensive focus on single-chip testing, from simple water lights began to gradually lead the U.S. from these simple few lines or a few lines of 10 procedures to familiarity with and understanding of SCM commands.

C8051F32X的usb鼠标例程，c语言编写，包含完整的通信协议-C8051F32X the usb mouse routines, c language, contains a complete communication protocol

用AVR 音乐合成： 1.音乐数据存放于芯片的flash存贮器中2.PA口显示不同的音阶变化。 3.音乐数据的低四位选择音调频率，高四位*5后，为音调持续时间。-Using AVR Music Synthesis: 1. The music data stored in flash memory chips in the mouth 2.PA show different changes in scale. 3. The music data to choose the four tones of low frequency, high 4* 5, in order to tone duration.

利用51单片机演奏音乐。定时器控制歌曲的频率（音调），延时时间控制节拍，可以轻松更改为自己想要的歌曲-The use of 51 single-chip music. Timer control of song frequency (pitch), delay time to control the beat, you can easily change the songs you want

This code implements the basic functions for an I2C slave device using the SSP module. All I2C functions are handled in an ISR. Bytes written to the slave are stored in a buffer. After a number of bytes have been written, the master device can then read the bytes back from the buffer.

P89C52对SJA1000的经典设计 使用了ZLG的隔离收发一体芯片 不可错过！-P89C52 of SJA1000 classic design uses isolation ZLG transceiver chip not to be missed!

51系列单片机在基本的开发例程，不错噢。-51 Series MCU in the development of basic routines, Oh well.

基于51的单片机的PPP协议实现，源代码-51 Based on the SCM PPP protocol, the source code

基于51系列单片机实现8字数码管对时钟秒表的显示-MCU eight characters of the digital clock shows the stopwatch

PIC汇编语言样例程序集一，非常好的芯片驱动-PIC assembly language sample program sets a very good driver chip
