摘要
针对γ辐射监测系统,应用ARM微处理器控制多通道AD芯片,实现对4路输入信号的高速数据采集。详细介绍了LPC2300系列ARM与高速模数转换芯片AD7656-1基于SPI串行通信的应用方案,给出了二者之间的硬件连接图以及μC/OS-Ⅱ实时操作系统下的软件实现方法,为ARM嵌入式系统在高速数据采集方面的应用提供了一个解决方案。
In the system of γ radiation monitor, ARM microprocessor is used to control a kind of simultaneous sampling ADC to acquire 4 - channel input signals in high speed serial interface. The paper presents the appli- cation of SPI to the serial communication between the LPC2300 ARM microprocessor and the high - speed ADC （ AD7656 - 1 ）, and describes the hardware connection of the ARM and the AD7656 - 1 as well as the imple- mentation of its softeware design under μC/OS - 1I real time operation system, it alse gives a solution for the application of ARM embedded system to high - speed data acquisition.
