IBM—PC与TP86A单板机的通信系统通过连接IBM—PC机的打印机适配器与TP86A单板机的并行外设接口及开发相应软件,使两者之间建立了通信渠道,从而大大改善了TP86A 单板机应用程序的开发环境,并有效地降低了单板机的软硬件成本。程序员可借助IBM—PC的软、硬件功能,开发适合于TP86A单板机的应用程序,并通过接口线路传送给TP86A单板机:单板机存储器中的信息也可以方便地传送给IBM—PC计算机系统。从而改善单板机内程序或数据的存储方式及拷贝手段,该系统接口原理简单且通用性强,适用于具有通用打印机适配器接口的IBM—PC,PC—XT及各种兼容机等。数据传输速率大于每秒0.25k 字节。
IBM-PC and TP86A single-board computer communication system By connecting the IBM-PC printer adapter and TP86A single-board parallel peripherals and development of the corresponding software, so that the establishment of a communication channel between the two, thus greatly improving the TP86A Board machine application development environment, and effectively reduce the single board machine hardware and software costs. Programmers can leverage the hardware and software capabilities of IBM-PC to develop applications that are suitable for the TP86A single-board computer and send them to the TP86A single-board computer through interface lines: The information in the single-board memory can also be easily transferred to IBM- PC computer system. Thereby improving the storage method and copy means of the program or data in the single board computer. The system interface principle is simple and versatile, and is suitable for IBM-PC, PC-XT and various compatible machines with a universal printer adapter interface. Data transfer rate is greater than 0.25k bytes per second.
