rs232实验 可以看看是综合实验 需要的人 是51的板子 用keil编译(the rs232 experiment to see people in need of comprehensive experimental 51 board keil compiler)

说明：  基于STM32F407的LED音乐频谱，AD+DMA采集音乐信号，利用FFT运算得出音乐频谱，通过10*8的LED点阵显示的音乐频谱单片机代码(Based on the LED music spectrum of STM32F407, AD+DMA collects the music signal, obtains the music spectrum by FFT operation, and displays the music spectrum code by 10*8 LED dot matrix.)

这是一个51单片机的菜单设计例程，使用时要做一些修改(This is a menu of 51 single-chip design examples, used to do some modifications)

ADS1298 開發於MSP430XXX 源碼(ADS1298 for MSP430 Front-End Performance Demonstration Kit)

按键的去抖以及按键弹起时读按键 (Reading keys key debounce and key bounce)

本例程是基于KILE的AT89C52系统板的全套开发例程和相关外设的原理图，实物图。(This routine is based on the AT89C52 KILE complete development system board routines and related peripherals schematics, physical map)

EMD（经验模态分解）的C语言实现程序，调试后可用(EMD (EMD) of the C language program)

实现RC522射频芯片的读写，扣费，注册，和充值等功能，51单片机绝得可以用(RC522 RF chip to read and write, chargeback, registration, and recharge function, 51 MCU must have to be able to use)

Using a servo motor and an ultrasonic sensor is a nod to the robot dog

关于msp430单片机的源代码，里面有很多比较有用的实例讲解，可以很好的利用，特别是对于初学者，是很好的资料(Msp430 microcontroller on the source code, there are many more examples of useful explanations, can be well used, especially for beginners, is a very good information)
