TP801单板机以它的价格低廉及用途广泛而大量地应用于各个领域。由于单板机自身不带汇编程序,只能使用机器语言,因此在编程过程中容易出错,且往往由于做稍许改动而化费大量时间,而专用的开发系统又太昂贵,不能普遍采用。本文介绍一种方法,只需在单板机上改动一根线,不增加其他硬件,就可在不影响原机任何功能的情况下,实现单板机与IBM PC之间的通讯。这样就可以利用IBM PC丰富的软硬件资源,把Z80汇编文件交叉汇
TP801 single-board machine with its low price and versatility and widely used in various fields. Because the board machine does not come with assembler, it can only use machine language, so it is prone to error in the process of programming, and it often costs a lot of time because of slight changes. The dedicated development system is too expensive and can not be used universally. This article describes a method that allows communication between the board machine and the IBM PC without changing any of the original machine functions by simply changing one line on the single board machine without adding additional hardware. This will take advantage of the rich hardware and software resources of IBM PC and cross-connect the Z80 assembly files
