目前,各部门中单板微型计算机的应用比较普遍,成效也很显著.但是一般情况下,单板机都没有配备打印机,这给调试程序带来了很多不便.本文介绍一种简单实用的方法,说明如何把打印机和单板机连接在一起以及怎样编写程序、把内存中的内容打印出来.考虑到Z80CPU组成的单扳机使用较普遍,因此选用该种单板机为例.一、打印机的选择由于单板机上都有供用户使用的并行接口,因而 At present, the application of veneer microcomputers in various departments is relatively common, the effect is also significant, but in general, the single-board machine is not equipped with a printer, which brings a lot of inconvenience to the debugger.This article describes a simple and practical method , Shows how to connect the printer and the single-board machine and how to write programs to print out the contents of the memory. Taking into account the composition of the Z80CPU single trigger is more common, so choose the single-board machine as an example. Select because the single board machine has a parallel interface for users to use
