| Abstract: | Applying USB interface to the data acquisition can efficiently increase data acquisition speed,strengthen anti-jamming ability and improve data transmission reliability.In this text,we bring forward a USB interface transmitted solution based on ARM technique,which take advantage of the high transmitting feature of USB,and choose S3C44BOX as the main controller.In this data acquisition system,high frequency analog signal is transformed to digital signal in AD7829 analog-digital converter after the preamplifier and gain adjustment so as to accomplish a 8-path data acquiring,then realize the fast data transmitting between interface chip ISP1581 and PC.Both hardware and software fulfill the requirements of the system and fast & accurate sampling and processing can be achieved. |
