The elective system is sometimes inefficient since it heavily depends on internet network. This paper proposes a scheme of elective system based on GSM message, and formulates the hardware and software design of the system. The hardware consists of micro-processor STM32103, GSM module, and some peripherals. The software is designed based on idea of finite state machine, which can receive/decode/store the GSM message and communicate with host computer. The test results show that the proposed system can perform the course election function effectively.
