PP40描绘器与 80C552单片机接口 ,可以构成带有实时打印输出的高性能的智能仪器或便携式仪表 ,也可构成带实时就地打印输出的控制系统。文中介绍了 80C552单片机与PP40描绘器的两种硬件接口方法 ,即直接接口法和通过 82 55与PP40接口法。硬件接口和软件编程灵活方便 ,经过实际运行 ,效果良好。 80C552单片机与PP40描绘器的接口具有较强的实用性和广泛的应用范围。
The PP40 tracer interfaces with the 80C552 microcontroller to provide high-performance smart instruments or portable gauges with real-time printouts, as well as control systems with real-time printouts in place. This article describes two kinds of hardware interface methods 80C552 MCU and PP40 trackers, that is, direct interface method and through the 82 55 and PP40 interface method. Hardware interface and software programming flexibility, after the actual operation, the effect is good. The interface of 80C552 one-chip computer and PP40 delineator has strong practicability and extensive application range.
