基于TMS320F2812的高速数据采集系统

摘要

8 roads sync signal was collection by using TMS320F2812 DSP and MAX13O8 AD coverter. Collected data rela-time transited to the computer by CH372 USB inerface chip, and the data acquisition process controled and displayed by computer. The system can realized 800kbps real-time date transmission in single road of date acquisition and 400kbps in 8 roads synchronous collection.%采用TMS320F2812型号的DSP和MAX1308型号的AD转换器完成对8路同步信号的采集,通过USB接口芯片CH372将采集到的数据实时传输给计算机,计算机对整个数据采集过程进行控制并显示.该系统对单路的数据采集,可以实现800kbps的实时数据传输,8路同步采集可以实现400kbps的实时数据传输.
