摘要
在大屏幕显示系统中用ＶｉｓｕａｌＢａｓｉｃ３．０实现了微机与８０３１单片机之间的双机通讯．描述了大屏幕显示系统的硬件组成及工作原理。
The communication between IBM-PC and MCS-51 single-chip microcomputer in the large screen display system was developed with Visual Basic 3.0. The hardware architecture and principle of the system were also proposed. The designing method of communication programs for PC and single-chip microcomputers was also described in detail.
