Abstract

This paper presents the hardware and software structure of a gyroscope-based angular position measurement system. The proposed system contains a rotary platform which can be rotated manually. The gyroscope is attached to the centre of the platform and is connected to a MSP430 microcontroller via SPI interface. The current angular position of the platform is displayed in real time on the screen of a personal computer (PC). This facility is possible because the microcontroller sends the measurement data to the COM1 port of the PC using an UART peripheral module. The main sources of errors, namely the influence of the temperature and the gain error, are considered and then removed. Experimental results which prove the functionality of the system are also presented.
