| Abstract: | This paper introduces the design and implement of a high-speed,high-accuracy,muhiple-channel data acquisition system based on ARM7 technology. Analog signal conditioning circuit was discussed at first. Then introduced the interface circuit between the ARM7 processor S3C44BOX and the AD7663 analog-digital converter, and analyzed the code of the data acquisition program. Some point of view to the PCB design of the high-accuracy data acquisition system was put forward at the endof this paper. |
