单片微处理机系统是许多小型控制仪器中常用的器件。单片微处理机系统的开发有其特殊的问题,其原因在于单片微处理机系统中许多数据只在芯片内部传输、寄存,而在外部引出脚上是不可及的,因此就造成调试时的困难。单片微处理机系统可以有两种用法:一种是不作任何扩充,一个系统就是一片芯片;另一种是用单片机,再根据其功能不足适当扩充一些硬件。对于第一种应用,如用带ROM的8048和带EPROM的8748,不存在硬件调试问题,因为全部硬件都已集成,是保证可以工作的,所以对它们的调试主要是软件的调试以及输出输入的调试。软件调试可以有几种方法。
Monolithic microprocessor systems are commonly used devices in many small control instruments. The development of a monolithic microprocessor system has its own special problems because much of the data in a monolithic microprocessor system is transmitted and stored only within the chip and is not accessible on the external pins, Difficulties. Single-chip microprocessor system can be used in two ways: one is without any expansion, a system is a chip; the other is the use of single-chip, and then expand the appropriate number of hardware according to their lack of functionality. For the first application, such as the 8048 with ROM and the 8748 with EPROM, there is no hardware debugging problem, because all the hardware is integrated and is guaranteed to work, so the debugging of them is mainly the debugging of software and the input of output Debugging. There are several ways to debug software.
