说明：  基于51单片机的ic卡门禁 有密码输入 ic卡登记 功能(Based on 51 single chip IC card entrance guard has password input function of IC card registration)

说明：  基于c8051f340的AD转换后数据由串口UART输出(AD converted by the serial UART data output)

Data structure and algorithm

本设计是以单片机为控制核心，通过液晶实时显示时钟，并通过LM35D传感器测量温度，将温度值实时显示在液晶上。(The design is based on microcontroller core, real-time via the LCD display clock, and through LM35D sensors measure temperature, the temperature values ​ ​ displayed in real time on the LCD.)

计算器，阈值为99999999，加减乘除运算都没有问题，protues电路图 和 汇编语言都有，仿真过了，没问题。(caculator， with protues and keil software it is successed。hope it is helpful for you)

超声波浓度计 采用混合信号处理芯片c8051f021与12864与485芯片同时输出4-20mA电流(Ultrasonic densitometer mixed signal processing chips c8051f021 and 12864 and 485 chips while the output 4-20mA current)

SPI Comm. for MSP430F5438

说明：  使用超声波测量距离，可以参考一下这个代码，适用于32。(Using ultrasonic to measure distance, you can refer to this code, which is suitable for 32.)

此文档是关于5643协议的测试计划，非常好的参考资料(This document is a test plan for the 5643 agreement, a very good reference)
