16位按键扫描程序,包含数字钟计时,闹钟报警,及定时应用

这是一个51单片机与PC的通信系统：利用3*4小键盘输入0~9的一串数字（不大于5），通过8051自带的串口发送给PC并显示在系统的6位LED上；单片机接收上位机的输入并显示在LED上。8051串行口经232电平转换后，与PC机串行口相连。PC机使用串口调试应用程序V2.2.exe，实现上位机与下位机的通讯。-This is a 51 microcontroller and PC communication system : use 3* 4 0 small keyboard input of a bunch of nine-figure (no more than 5), by 8051, bringing their serial sent to the PC and display system in the six LED; SCM receiving PC input and displayed on the LED on. 8,051 by 232 serial port-level conversion, and the PC serial port connected. PC using serial debugging applications V2.2.exe achieve PC and the next crew communications.

基于AVR单片机mega8的电表的C程序（第二部分，时钟及其他）-Based on the AVR Microcontroller mega8 meter of C procedures (the second part, the clock and others)

这个程序比较实用,主要功能是检测温度.进行温度的设置.使用的是DS18B20温度传感器.显示使用LED.-this procedure is practical, Detection is the primary function of temperature. temperature settings. using the temperature sensor DS18B20. that the use of L ED.

595串入并出芯片的驱动程序，大大减少了输入数出口在单片机开发系统中显示上所占用的数量

AVRX 是一个为AVR单片机写的操作系统，尺寸较小，使用方便，但核心部分为汇编，这里是一个C语言写的核心-AVRX is a single-chip AVR write the operating system, smaller sizes, and easy to use, but the core part of the compilation, here is a C language to write the core

Point RTOS 主要是一个针对小系统开发而设计的实时操作系统。 目前，Point RTOS 仅提供对51系列及其扩展系统单片机的支持， 针对51内核函数不能重入以及51单片机的内存空间管理方式等因素， RTOS放弃了抢先式内核的调度，而使用了时间片的调度方式，除非任务主动放弃， 否则任务将独占CPU一直运行，因而任务中必须完成对本次操作的时间片设置，即等时间的设置。-Main Point RTOS is a small system development and design of real-time operating system. At present, Point RTOS only provide for 51 series and its expansion of the system single-chip support for 51 core function should not re-entrant, as well as 51 single-chip memory space management and other factors, RTOS abandoned preemptive kernel scheduling, the use of a scheduling time slice manner, unless voluntarily chose to abandon the mission, or mission will be exclusive CPU has been running, which must be completed in the mission of this operation time slice settings, that is, the time settings.
