DHT11的C51驱动程序，4位数码管可以显示温度和湿度，带一触发按键(DHT11 C51 driver, four digital tube can display temperature and humidity, with a trigger button)

以上是二维傅里叶变换程序源代码 还有傅里叶反变换(These are the two-dimensional Fourier Transform source code for inverse Fourier transform)

模拟电表软件，主要模拟电表数据、遥测数据、参数修改、报文显示、可以模拟2个电表（可以自行修改增加），最终通过RS232转485输出。。。(Analog meter software, the main analog meter data, telemetry data, parameter modification, message displays, you can simulate two meters (which can be modified to increase its own), the final output through the RS232 switch 485. . .)

Iar环境下avr_bootloader的编写，可以参考参考。(Preparation of Iar under the environment of avr_bootloader, can refer to the reference.)

TCS3200传感器捕获方波频率，可以根据频率变化识别外部光源颜色(TCS3200 sensor to capture a square wave frequency, the frequency change can identify the external light source color)

使用MSP430F5438单片机和HC-SR04超声波模块实现测距的源码。( Using the MSP430F5438 microcontroller and HC-SR04 ultrasonic ranging module source.)

通过一个简单例子，说明C语言对于学习单片机的重要性，有助于新手的入门.(By a simple example to illustrate the C language for learning the importance of SCM to help novice entry.)

说明：  多路温度测试模拟,使用VB写的，只是模拟(Many way template test source)

超声波测距模块扩展实验，使用超声波传感器，把数据结果显示在1602上。(Ultrasonic Ranging Module extension experiments using ultrasonic sensors, and display data results in 1602.)

读取ssdt函数当前地址，详见源码中、。。。。(Ssdt function reads the current address, see the source code. . . .)
