说明：  1.GPIO输出控制实验-控制Led亮灭，zigbee 控制LED亮灭(1. GPIO output control experiment - control LED on and off, ZigBee control LED on and off)

matlab实现的单相PWm……，对于搞pwm的非常有用(single phase pwm implemention inmatlab，非常实用)

项目用到的STM32F103芯片SPI接口的SD卡读取与改写存储，带文件操作FAT32操作系统，绝对可以用。(The STM32F103 chip SPI interface of the project uses the SD card reading and rewriting storage, and the file operates the FAT32 operating system, which is absolutely available.)

说明：  用8个发光管演示出8位二进制数累加过程。(With 8 LED demo out eight binary cumulative process.)

一个LED灯带的程序，通过红外遥控器进行遥控，实现变色，七彩跳变等功能(LED lights with a procedure carried out by remote control infrared remote control to achieve color, colorful hopping function)

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.)

ADS1258开发，程序源代码，还要20字 好恶心(ADS1258 development, source code, but also the word disgusting 20)

TFT——ssd1289操作方式为GPIO方式(TFT- ssd1289 mode of operation for GPIO mode)

本程序可实现基于51单片机的电子秤数据采集、滤波、显示功能。 称重范围：0-1000g 分辨率： 0.1g 测试精度：0.2g 设计架构：采用弹性悬臂梁贴应变片的传感器结构，应变片采用全桥连接。电桥输出经AD芯片发送给微处理器，微处理器经过数据处理后显示。(This program can realize the functions of data acquisition, filtering and display of electronic scale based on 51 single chip computer. Weighing range: 0-1000g Resolution: 0.1g Testing accuracy: 0.2g Design framework: The sensor structure of elastic cantilever beam with strain gauge is adopted, and the strain gauge is connected by full bridge. The output of the bridge is sent to the microprocessor by AD chip, and the microprocessor is displayed after data processing.)
