摘要
系统利用ARM9、CPLD、TL16C554设计多串口扩展系统的方案,首先介绍ARM9处理器S3C2440、CPLD芯片EPM3128、四路串口扩散芯片TL16C554的特性,随后介绍多串口扩展系统的硬件设计,最后详细介绍CPLD硬件程序代码以及TL16C554的WINCE驱动程序设计和WINCE应用程序设计。
This paper proposes a multi-serial extension system solution based on ARM9 CPLD TL16C554. There is first a general introduction of the micro-processor S3C2440, CPLD chipset EPM3128 and four-channel serial extension chip TL16C554. Following the brief introduction, the paper presents hardware design of multi-serial extension system. Finally the paper describes the CPLD hardware process and the WinCE driver program of TL16C554 , and the application program design of TL16C554 based on WinCE.
