基于89S51芯片开发的篮球倒计时系统，开发…

单片机与计算机的互连，C51的Keil工程文件和PC机的C++文件。-Single-chip interconnection with the computer, C51 of the Keil project file and PC-C++ files.

液晶显示模块手册中文详细说明，解决英文难懂的问题

采用两片凌阳61实现的建简易智能车程序，包含寻迹，金属探测，语音播报等功能-The use of two 61 Sunplus built realize the mini-mental procedures, including tracing, metal detector, voice broadcast and other functions

应用于51的浮点数计算器程序，其中键盘的扫描程序需自己写（我不想让人都懒起来），还有就是LCD显示部分，根据情况更改-applied to the float 51 calculator program, the keyboard scan process required to write their own (I do not want to have lazy up), the LCD display is also part of the changes under

MSP430 F149的单片机 AD转换 便于相应计时器的操作-MSP430 F149 microcontroller AD converter to facilitate the operation of the corresponding timer

PC机端程序，实现PC机与单片机的发送和接受通信.-PC-side procedures, and realize PC-MCU to send and receive communications.

TLC549是一种采用8位逐次逼近式工作的A/D转换器。内部包含系统时钟、采样和保持、8位A/D转换器、数据寄存器以及控制逻辑电路。TLC549每25uS重复一次“输入―转换―输出”。器件有两个控制输入：I/O CLOCK和片选（CS）。 内部系统时钟和I/O CLOCK可独立使用。应用电路的设计只需利用I/O时钟启动转换或读出转换结果。当CS为高电平时，DATA OUT处于高阻态且I/O时钟被禁止。 -TLC549 is a used 8-bit successive approximation type of work the A/D converter. Contains the internal system clock, sample and maintain, an 8-bit A/D converter, data register and control logic circuit. TLC549 each repeat 25uS

一个I2C为驱动的一个时钟芯片程序，很有用的，大家好好学习吧-A I2C-driven one clock chip procedures, very useful, you study hard everyone

功能： 1、作为下位机采集8255数据并将此数据通过通讯送出， 2、采集数据为BCD，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1
