文档介绍：基于SPCE061A和SPR4096的公交车自动报器的研究
摘要
凌阳十六位单片机SPCE061A采用凌阳最新推出的µ’nSP 16 位微处理器内核(以下简称µ’nSP)。SPCE061A内嵌32K字(Word)闪存(FLASH),2K字(Word)SRAM,有多达十四个的中断源等丰富的片内资源。CPU最高可工作在49MHz的主频下,较高的处理速度使µ’nSP能够非常容易地、快速地处理复杂的数字信号,这使得SPCE061A具有灵活的语音处理能力。因此,本设计应用此单片机,公交车自动报站器主要实现了自动报站和时间显示的功能。本文主要讨论了应用SPCE061A精简开发板——61板、LED键盘显示模组、SPR模组_4096实现简易的公交车报站器系统中软件部分的实现。

The software process of system to realize the bus
announcing station automatically
Abstract: The spec016a is a 16-bit SCM of sunplus, which uses the newest nsp-16 MPU kernel of sunplus( abbreviated μ'nSP). The spec016a is available with both 32k-word flash and 2k-word SRAM with fourteen interrupt port. The CPU can work under the condition of the maximum main frequency 49MHz. The higher processing speed makes it easy and rapid that the μ'nSP plex digital signals. Therefore the spec016a can process sound flexibly. Automatic announcing bus station system that is designed based on the spce016a realizes announcing bus station and time display. This paper discusses the software process of system to realize the bus announcing station automatically, which is based on the SPCE061A version 61、 LED、 key display mode and SPR4096 mode.
