摘要
介绍一种以高性能模拟微控制器ADuC812为核心的录波装置。该装置利用ADuC812片内A/D转换器及其DMA方式实现对模拟信号波形的采集和记录,并可将结果通过USB接口保存到外置USB存储设备或通过RS-232接口传送到PC机中进行分析处理。文中介绍了该装置的设计思想、硬件电路以及DMA方式A/D转换的基本步骤。
A waveform- recording equipment with high -performance MCU ADuC812 is introduced. This device employs the on - chip A/D conversion and its DMA function to accumulate and record analog signal waveforms and save to USB storage device or to transmit the outcome to PC for analysis. The designing thoughts and hardware circuit of the device and the basic procedures of A/D conversion by DMA approach are to be discussed with emphasis.
