【摘要】 采用TI公司的通用异步接收发送设备(UART)芯片完成数字信号处理器(DSP)与PC机之间的串行通信,可以避免常规的对DSP的多通道缓冲串口(MCBSP)复杂的软件编程模拟,不仅编程简单,传输能力强,而且实时性好,可靠性高。文中简单介绍了一种UART芯片TL16C550C,并给出了它与TMS320VC5402连接的硬件电路以及软件编程方法。更多还原

【Abstract】 The serial communication between DSP and personal computer can be realized by using UART CMOS chip of Texas Instruments Inc., which can avoid writing the complicated software routine for the McBSP of DSP, and has the advantages of simple programing high transmission capability, good reliability and real-time capability. In this paper, we introduce briefly a kind of UART COMS chip TL16C550C and provide the hardware circuit between TL16C550C and TMS320VC5402 and the way how to program it.更多还原
