avr单片机与CS5460的汇编程序，实现了对cs5460的初始化和读写等功能-avr Microcontroller and CS5460 compilation process, the CS5460 realize the initialization and read-write functions

pic单片机c口的控制 单片机相应的I/O口设置为输出口，输出高电平时LED点亮，反之，LED不亮。利用软件延时的办法实现05S延时，实现LED流水灯的效果。-pic Singlechip c I control the corresponding single-chip I/O port set to output, the output high when the LED light, on the contrary, LED does not shine. Approach to the use of software latency delay 05S realize, realize LED lights flowing effect.

SST89E58RD仿真器的制作有关的PCB,说明和监控程序,可以用来对51单片机进行仿真-SST89E58RD simulator produced the PCB, description and control procedures can be used for 51 single-chip simulation

目前市场上有很多语音录放系统，如录放音玩具、录音笔等，大多采用了单片机控制一个语音芯片，再接一个FLASH存储器的结构。单片机可以控制录放时间，选取特定时间段的播放以及单多声道的录放，容易通过改变外接存储FLASH改变录放时间。 我们做的是一个简单模型，只能录放。 只需要录音和放音时的外部 ROSC 端振荡电阻不同就能改变声音的录入和播放速度，录入的时间越短音质越好，录入的时间越长音质越差 它采用模拟量直接存贮技术，因此保真度高，音质好 -Currently on the market there is a lot of voice recording systems, such as sound recording toys, sound recording pens and so on, most of the single-chip microcomputer to control the use of a voice chip, making the structure of a FLASH memory. Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct ana

这是一个模拟I2C通信协议的C语言模块，可以在基于51系列单片机的C语言程序中进行调用，调用方式我在模块中已经添家了详细的说明，请自己查阅！-This is a simulation I2C communication protocol C language module, Based on the 51 Series MCU C language program which calls, Call module way I have Tim home detailed description, please check themselves!
