Abstract:
This paper introduces an eight channels dada acquisition system. A peripheral circuit based on C8051F340 MCU has been designed and its USB controller is used to transfer data, which realizes real-time detection, display and storage of bowel sounds. The system has many advantages such as high precision and stable performance, and thus provides a new means for the bowel sounds study.
