8051单片机控制1602LCD实现动态数据显示，具有走数功能。-8051 Dynamic 1602LCD control data, with a way to function.

用单片机的C语言编的键盘递增递减的C程序的源代码（按一下键，对应的键值增或减一），在很多领域用到此思想，如空调调温等，可供单片机开发工程师参考。-the MCU series of the C language keyboard incremental decrease in C program"s source code (by pushing a button, the corresponding increase or decrease of the pair a), used in many areas here thinking, such as air-conditioning thermostat, MCU development engineers for reference.

独立式按键扫描并在一个LED数码管上显示相应的编号。-Stand-alone scan button and a LED digital tube display on the corresponding number.

AVR单片机入门及C语言高效设计实践（四） ATMEAG16L的I／O端口特点及使用 ATMEAG16L单片机有32个通用I／O口，分为PA、PB、PC和PD四组，每组都是8位。这些I／O口都可以通过各自的端口寄存器设置成输入和输出（即作为普通端口使用），有些I／O口还具有第二功能（我们在后面使用到这些第二功能时再介绍）。-AVR C language portal and efficient design practice (4) ATMEAG16L the I/O Ports characteristics and use of a microcontroller ATMEAG16L 32 common I/O mouth into PA, PB, PC and PD four groups, each group are eight. These I/O I can through their respective ports Register set to input and output (that is, use as a general port), Some I/O I also have the second function (in the back of the use of these second function tell).
