ADC0809是广泛使用的模／数转换器，在可不采用外部总线结构的单片机系统中(如 由AT89C51组成的系统)。ASC0809的数据线直接与单片结构的I／0 口相连，并由单片机的I／O 口直接对ADC0809进行控制。-ADC0809 is widely used in analog/digital converters, in not using the external bus architecture in the single-chip microcomputer system (such as the composition of the system by the AT89C51). ASC0809 data lines directly with the monolithic structure of I/0 I connected the MCU I/O port directly to control the ADC0809.

系统以AT89S52单片机为控制核心，加以直流电机、舵机、光电传感器、火焰传感器和电源电路以及其他电路构成，设计报告完整，元器件选择比较恰当，制作的小车能完成题-AT89S52 Single-chip system for the control of the core, to DC motor, gear, photoelectric sensors, flame sensors and power supply circuit and other circuits, the design integrity of the report, more appropriate choice of components to produce the car to complete the title

这个源码是在电源上电过程中的处理程序，在单片机上电过程中需要有很多步骤去处理，供大家参考讨论-This source code is in the power supply in the course of treatment procedures, the single-chip power and the need to have a lot of steps to deal with, for reference to discuss

这是运用MSP430单片机 对键盘进行判别的程序 运用单片机引脚的中断功能 使得只用一次扫描就可以 识别键盘码 -This the use of the keyboard MSP430 the procedures for identifying the microcomputer-pin interrupted feature allows only one scan can be identified keyboard code

本代码是无线遥控中常用的pt2272模块的主控单片机代码，实现了编址发送功能。-the wireless remote control code is used in the main control module pt2272 microcontroller code, Implementation of the address this function.

步进电机单片机驱动程序-stepping motor driver program

PC机与单片机串口通讯可以通过多种方式来实现，在这里只介绍使用MSCOMM控件进行通讯。-PC and microcontroller serial communications to be many ways to achieve here in only MSCOMM controls on the use of communication.

点阵式打印机驱动程序,CPU:89C51RD2,含3562个汉字,可打印图形,有1024字节缓冲区-Dot-matrix printer driver, CPU: 89C51RD2, including 3562 Chinese characters can print graphics, has 1024-byte buffer

功能： 1、作为主机通讯采集两路下位机数据并将此数据通过8255送出（十路水位值） 并计算水头送STC板 2、采集数据为BCD码制，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 在此系统中本机硬件地址要设为0-Features: 1, as the host of two-way communication acquisition of data-bit machine and send this data through 8255 (the road level 10 value) and calculate the head sent to STC board 2, for BCD code data collection system, the first converted into binary, and then deal with the conversion into BCD 3, communication using methods 3, multi-machine communications, address PC made 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 in this system to the local hardware address set to 0
