摘要
为了快速、准确地进行数据采集,并把采集到的数据显示出来,设计了一种以TI公司的TMS320F2812内置ADC为数据采集核心、以MAXIM公司的MAX7219作为LED显示驱动的方案。从硬件和软件两个方面的设计进行阐述,重点介绍了软件方面的设计。调试结果证明,该设计能够达到数据采集的要求,并能稳定地显示采集到的数据,可以广泛应用于仪器仪表设计中。
As to collect data rapidly and exactly, and to display the collected data, a design which adopts inside ADC of TMS320F2812 from TI incorporation as the center of data acquisition, and uses MAX7219 from MAXIM incorporation as driving of LED displaying, is presented in this paper. Both hardware and software design are discussed, and software design is given in detail. The result of debugging indicates that the design can meet the requirement of data acquisition and the collected data can be displayed stably, which can be widely used in instrument design.
