说明：  03年电赛题目 51单片机实现 包括红外光电传感器 金属传感器 寻光检测 循迹避障等(2003 title game 51 power MCU including infrared photoelectric sensor to find the light sensor detects metal tracking obstacle avoidance, etc.)

① 设计进程控制块PCB表结构，分别适用于优先数调度算法和循环轮转调度算法。 ②建立进程就绪队列。对两种不同算法编制入队子程序。 ③编制两种进程调度算法：1）优先数调度；2）循环轮转调度 (① design process control block PCB table structure, respectively, for priority scheduling algorithm and round-robin scheduling algorithm. ② establish a process ready queue. Two different algorithms for the preparation of subroutine into the team. ③ preparing two kinds of process scheduling algorithm: 1) priority scheduling 2) round-robin scheduling)

说明：  STC15W4K56S4 4串口均已初始化，可正常使用。(STC15W4K56S4 four uarts.)

这是一款模拟modbus从机的程序，可以方便用户调试modbus程序，本程序完全免费。(This is a simulation of the modbus from machines, can facilitate users to debug the modbus program, this program is completely free. )

DC Motor Control using PWM with ADC

IC 74HC595 to Display 8*LED

一个通用的24C01－24C256共9种EEPROM的字节读写操作程序，此程序有五个入口条件，分别为读写数据缓冲区指针,进行读写的字节数，EEPROM首址，EEPROM控制字节，以及EEPROM类型。此程序结构性良好，具有极好的容错性，程序机器码也不多。(A generic 24C01-24C256 total of nine kinds of EEPROM byte read and write operating procedures, this procedure has five entry conditions, namely, to read and write data buffer pointer, the number of bytes to read and write, EEPROM the first site, EEPROM control word Festival, as well as the EEPROM type. This program structured well, with excellent fault-tolerance, the program machine code is running out.)

STM32读取GPS信息并跟踪并短信发送到目标手机(STM32 reads GPS information and tracks it and sends it to the target cell phone by short message)

说明：  单片机一个按键三个功能：长按、短按、双击。 原创单键复用程序 绝对好用(SCM original program is absolutely easy to use with one-button re-)

stm32的usart1和usart3配置为串口通信，均用中断实现串口接收。(stm32 usart1 and usart3 configured for serial communication, both with the serial port receive interrupt achieve.)
