基于msp430的DDS芯片ad9851的源码,-MSP430 Based on the DDS chip AD9851 source,

采集数据后处理程序。在MS51单片机上可直接拷贝应用。-After data collection process. In MS51-copy single-chip can be directly applied.

一些常用的c51源码，编程时可以参考。-some frequently used source decoder, the reference can be programmed.

本程序采用AT89C51单片机，ADC0809模数转换芯片进行模数转换，最终由数码管显示“0809**”。-This procedure using AT89C51 single-chip microcomputer, ADC0809 analog-to-digital conversion chip for analog-digital conversion, and ultimately by the digital tube displays

将单片机的IOA0~IOA7分别接按键S1~S8连接到高电平上。此时，如果某个按键被按下，对应的I/O端口就会输入高电平进单片机，即按键S3按下，IOA2会输入高电平进单片机-Will Singlechip IOA0 ~ IOA7 access keys, respectively, S1 ~ S8 is connected to high on. At this point, if a button is pressed, the corresponding I/O port will enter into the high single-chip, that is, S3 button press, IOA2 will enter into single-chip high
