摘　　要：通过研究三线串行接口的构成原理,设计了一种基于MSP430单片机和FPGA的三线串行接口测试仪。该测试仪利用MSP430单片机来控制三线传输功能,由FPGA产生三线传输时序,由相应的上位机软件来测试数据通信。经测试,该测试仪具有使用方便、功能齐全、性能稳定等特点,能够较好应用于航天领域的三线串行接口通信测试中。Designed a three-wire serial interface tester based on the MSP430 MCU and FPGA by studying the constitute principle of the three-wire serial interfaee. The tester used MSP430 microcontroller to control the three-wire transmission function, the three-wire transmission timing generated by the FPGA and the corresponding host computer software is compiled to test the data communication. Test results show that the three-wire serial interface tester have the characteristics of easy to use, fully function,and stable performance, which could be better used in the three-wire serial interface communications test of the aerospace industry.
