摘要
文中结合实例详细介绍TMS320LF240x DSP的异步串行接口和串行外设接口。阐述异步串行接口与PC机之间的通信,以及串行外设接口在显示模块的实现,并对异步串行接口和串行外设接口作比较。其中PC机的通信利用VB的MSComm控件。
The SCI and SPI of TMS320LF240x DSP are introduced briefly in this paper. The communication between SCI and PC, and realization of SPI in display module is presented. Also, SPI is compared with SCI in this paper. The communication of PC is designed by using MSComm of VB.
