说明：  本文件是基于AT89C51单片机芯片的LED点阵显示文字的C语言工程文件(This document is based on the AT89C51 single chip LED dot matrix display text C language engineering document)

PC与单片机通信，计算机串口读取程序,非常实用，可以实现串口数据的读数和显示(read uart com data and play it)

RS485的通讯源代码，此代码主要是和单片机通讯的，初学者可以参考！(RS485 communication source code, this code is and the single-chip communications, beginners can refer to!)

说明：  本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)

时钟芯片CW1288的驱动程序，适合外挂时钟的系统(CW1288 clock chip driver for external clock system)

说明：  工程教育中级练习题1：按一下K1键，LED以10Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；长按K1键超过3秒，LED以5Hz频率闪烁，屏幕上画出红圈，跟着闪，放开后保持该频率闪烁；按一下K2键，LED熄灭；按一下K2键，LED常亮。(Secondary Exercise Question 1 in Engineering Education: Press the K1 key, the LED flickers at 10Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K1 key for more than 3 seconds, the LED flickers at 5Hz frequency, draw a red circle on the screen, follow the flash, and keep the frequency flickering after release; Press the K2 key, the LED goes out; Press the K2 key, the LED always shines.)
