This paper introduces a data acquisition system for a MEMS gyroscope using a PSoC development board, for use in infrared imaging guidance systems. Using a PSoC 5 as the control core, we proposed a design scheme with high quality, low cost, low power consumption, which satisfied the design requirements. We performed a detailed investigation regarding the realization process of the hardware and software of the PSoC 5. Static and dynamic experiments were designed for data analysis. It is shown that the data acquisition system has high measurement accuracy.
