【摘要】 针对TI公司的TMS320F28xx,在介绍DSP芯片主要特点的基础上重点阐述了它的串行通信模块,并描述了串行通信模块的两大加强特性,介绍了利用F2812串行通信模块实现其内部CPU与异步外设之间的串行通信的原理,并且结合实际应用,给出了异步串行通信的软件程序设计。实际应用结果表明,该方法数据传输可靠,解决了通信过程中对终端波特率的确定问题,减少了通信中断次数,提高了通信速率,有广泛的应用前景。更多还原

【Abstract】 Aiming at TMS320F28xx of TI company,the characteristics of DSP serial is introduced. Based on that, the synchronous serial communication module and its two enhanced properties are descripted. The communication principle between the internal CPU and the synchronous peripheral equipment is realized by using F2812 serial communication module. Combined with the real application, soft program design of the synchronous serial communication is given. The practical results show that the proposed method has the transfer reliability of data, the ability to determine the terminal baud, and the widely applications.更多还原
