Design of Highly Precise Automatic Weight Measure System Based on CS5532

This paper introduces the design and realization of automatic weighing system based on 24-bit high-precision serial A/D converter CS5532. From hardware design and software design, the paper introduces the interface circuit design between weighting sensor and CS5532 together with the application, the principle and the control method of the electromagnetic vibrator, and the circuit design of the zero crossing detection. Also, it introduces some anti-interference design.
