为了减小数据采集卡的体积，降低使用成本，介绍了一种采用STM32单片机来进行设计的数据采集卡。利用STM32内部集成了A／D转换、定时计数、脉冲捕捉等功能，外部信号经过转换处理和采集后直接由单片机USB接口输出，上位机LabVIEW程序接收数据完成显示和控制功能，实现了高速、宽量程、功能全、价格低、体积小、使用方便、显示形式多样的目的。

The design of data acquisition card based on the STM32 microcontroller was introduced to re-duce the size and cost.STM32 has internal functions like A/D converter,timing and counting,pulse capture, the external signal was acquired and output directly on MCU USB interface,and the data was received,dis-played and controlled through the LabVIEW program on the computer.High speed,wide measuring range,multi-function,lower price,smaller size,convenient use,multiple display were achieved in the data acquisition card.
