Abstract: The paper introduced the structure of harmonic measurement system of two-way asynchronous serial communication. A new-style interface circuit was designed with PC 16552 chip between TMS320C32 and PC. And CPLD controls receive/send signal of PC16552. It is shown that the interface can transmit data effectively and rapidly.
