Asynchronous serial communication between TMS320LF2407 inverter and host computer

In variable frequency regulating speed system,serial communication is widely used for telecommunication between inverter and host computer.The hardware interface design,communication protocol and software design of asynchronous serial communication between inverter based on the TMS320LF2407A and host computer was proposed in this paper.Then the initialization coding of DSP-SCI and how to realize asynchronous serial communication by MSComm in VC++6.0 was presented.
