摘要:

随着嵌入式系统对数据采集存储的要求更高,以STM32F103芯片作为系统主机,采用多通道模数转换芯片AD7793实现多路数据采集,并在LCD屏上显示出采集数据。同时使用USB控制芯片CH376设计USB主机接口,仅依靠收发串口指令来控制数据的读写,直接存储到移动存储设备,解决了单片机管脚资源少的问题。

关键词: STM32F103, AD7793, CH376, 串口指令

Abstract:

STM32F103 chip is adopted as the host to realize multi-channel data acquisition and storage.The multi-channel analog-to-digital conversion chip AD7793 is used for data collection,and the collected data is shown on the LCD screen.The USB host interface is designed based on USB control chip CH376,which control  the data read and write directly into mobile storage devices only by sending and receiving instructions via serial port,thus solving the lack of the micro-controller pin resources.

Key words: STM32F103;AD7793;CH376;serial port instructions
