串口发送数据，字符，12864接受并显示字符(Serial port to send data, the character, to accept and display the character 12864)

采用MSP430单片机控制VS1003芯片进行MP3播放， MSP430通过读取 SD 卡里面的MP3歌曲，将数据发往VS1003进行解码，然后通过音频输出进行播放。(VS1003 using MSP430 MCU control chip MP3 player, MSP430 by reading the SD card inside the MP3 songs, the data will be sent to the VS1003 is decoded and then played through the audio output.)

说明：  sketch_dec12a是arduino文件 读到上位机输出的字符串输出SD卡里面的语音信息。 sketch_dec12a是arduino文件 读到上位机输出的字符串输出SD卡里面的语音信息。(Sketch_dec12a is a string read from Arduino file to output from PC and output voice information in SD card.)

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)

Zooming: oversampling and Shrinking : undersampling Zooming requires two steps: Creation of new pixel locations, Assignment of gray levels to those new locations. To shrink an image by one-half, delete every other row and column.

RTK精密定位中的后处理程序，包含数据保存和输出的功能(RTK precision positioning in the post-processing procedures, including data storage and output functions)

XPT2046 四线触摸屏控制芯片,优化、代码规范注释清晰。共同分享。(XPT2046 4 LINE touch screen controller driver code。)

说明：  ADF4351锁相环的stm32程序，包括stm32f1和stm32f4程序，初始化晶振为25MHz，晶振可调(ADF4351 is a pll ,l provide the chengxu about the configution for adf4351)

这是一个有关AD7689的程序，只有驱动部分，使用的CPU是msp430F149。可以采集8路数据。不过数据在主程序中需要处理下，不然会有波动。(This is a program about the AD7689, only the driving part, CPU use is msp430F149. 8-way data can be collected. However, the data need to be addressed in the main program, the otherwise subject to fluctuations.)

音量控制芯片，六通道音量控制芯片，可单独和全控。(The volume control chip)
