C51单片机RTC实时时钟(DS1302)初始时间12：00：00数码管显示(The initial time of the the C51 MCU RTC real time clock (DS1302) 12:00:00 digital display)

MICROSOT 做ACTIVE MOVE FLASH的东东,此说明是其SDK的一部份(MICROSOT make the ACTIVE MOVE FLASH Dongdong, this note is a part of its SDK)

数字时钟显示时间、定闹钟及整点报时，还能实现时钟界面的切换功能(Digital clock displays the time, set the alarm and hourly chime)

parallel quicksort algorithm and implimentation

通过把开机次数记录在24C02中，并在数码管上显示出来， 124C02的写保护脚为低电平，即允许写(Boot number of records in the 24C02, and displayed on the digital 124C02 write-protect pin is low, that is allowed to write)

SIM900开发板配套STM32 GPRS代码(SIM900 STM32 GPRS driver)

说明：  惠普打印机 PCL5 语言 命令函数程序代码参考(hp pcl5 printing command reference)

单片机串口通信的应用，通过串口，我们的个人电脑和单片机系统进行通信。 个人电脑作为上位机，向下位机单片机系统发送十六进制或者ASCLL码，单片机 系统接收后，用LED显示接收到的数据和向上位机发回原样数据。(Single-chip serial communication applications, through the serial port, our personal computers and SCM systems to communicate. PC as a PC, send down bit microcontroller system or ASCLL hexadecimal code, after receiving the SCM system with LED display received data and sent back up crew as data.)
