摘　　要：提出了一种基于TI MSP430单片机的FSK调制解调器设计方案。根据FSK调制解调的原理与方法,选用MSP430F147单片机,设计了CCITTV2.1协议下的300波特调制解调器,并给出了实现调制解调器的硬件电路和程序流程图。实践证明:该设计方案结构简单、可靠性高、抗干扰能力强,有较高的性价比。The realization of FSK modulator-demodulator based on MSP430 was proposed. According to the principle and method of FSK modulator-demodulator, MSP430F147 was selected. 300 bit/s modulator-demodulator based on CCITT V2.1 was realized, and the hardware circuit and the program flow chart were presented. The practical operation shows that it has the following advantages simple structure, high reliability, strong anti-interference and high performance-price ratio.
