这是AVR 1602b字符液晶显示模块

通过环路串口判断串行通信电平转换芯片功能是否正常，并通过读写DRAM 判断硬件。-Through the loop to determine serial communication serial port level translator chip features and whether it is normal, and through reading and writing DRAM hardware judge.

一个用C51编写的倒计时程序，可通过PC传送起始时间，也可回传当前时间。比较简单-C51 with a countdown of the preparation process, through PCs starting time, but also back- the present time. Relatively simple

频率计，精度高，可以自动换档，一般单片机可以达到0…500k-Frequency, high precision, can automatic transmission, the general single-chip microcomputer can be 0 ... 500k

单片机用来实现数据排序程序（冒泡排序算法）-MCU used to achieve data sorting procedures (Bubble Sort Algorithm)

温度传感器AD7416C程序（能帮你了解I2C原理，及函数的使用）-AD7416C temperature sensor (I2C can help you understand the principles, and the use of function)

转载单片机实现TCP/IP协议的完整C源程序，带程序注解的，供大家研究-reproduced MCU TCP/IP protocol complete C source code, annotated with procedures for everyone to consider! !

c51程序库，汇编写的，希望对大家有点用。-C51 libraries, compiling written, in the hope that a bit with everyone.

这是一个电子电位器源代码,内有两种程序,一个是通过位操作,另一个是通过地址总线操作-This is an electronic potentiometers source code, there are two procedures, a bit through the operation, and the other is through the address bus operation
