目前越来越多的单位开始使用自动广播,其类型也是多种多样的。我们设计的自动广播机是由INTEL 8748单片机和ASTRO十功能电子表构成的,它具有电路简单、容易调试和工作可靠等优点。本文主要介绍有关电路及程序设计等问题。用ASTRO电子表为单片机提供时间基准并作时间显示。既然单片机本身通过运转程序也能产生时间基准,为什么又要另用一只电子表呢?因为如果不用电子表,就会使单片机的硬件和软件复杂化。十功能电子表不但能提
At present, more and more units begin to use automatic broadcasting, and their types are also varied. We design the auto-announcer is composed of INTEL 8748 microcontroller and ASTRO ten functional electronic form, it has the circuit is simple, easy to debug and work reliably and so on. This article mainly introduces the circuit and program design and other issues. Use ASTRO electronic timepiece to provide a time base for the microcontroller and display the time. Since the microcontroller itself can also generate a time base by running the program, why not use another electronic watch? Because if you do not have an electronic watch, it will make the microcontroller hardware and software complexity. Ten functional electronic watch can not only mention
