在石油勘探和开发生产中 ,大量使用智能型仪器和便携式仪器。利用 80C5 5 2单片机丰富的输入输出功能 ,使单片机与具有较高智能化程度和卓越性能的TPμP -A系列微型打印机接口 ,可以使这些仪器具有实时显示和打印输出功能 ,既方便野外作业 ,又可避免人工记录数据的错误。 80C5 5 2单片机与TPμP -A系列微型打印机的接口方法灵活方便 ,软件编程容易。文中介绍了并行接口法 (直接接入总线法 ,通过 82 5 5接口法 )和串行接口法的电路原理和部分实用程序 ,这些程序都通过了实际运行 ,可以直接应用。
In the oil exploration and development and production, extensive use of smart instruments and portable instruments. The use of 80C5 5 2 MCU rich input and output capabilities, so that the MCU with a higher degree of intelligence and superior performance TPμP-A series of micro-printer interface, these devices can make real-time display and print output, both for field operations, and Can avoid the error of manual record data. 80C5 5 2 MCU and TPμP-A series of micro-printer interface method is flexible and easy, software programming easy. This paper introduces the parallel interface method (direct access bus method, through the 82 5 5 interface method) and the serial interface method of circuit theory and some practical procedures, these programs have passed the actual operation, can be applied directly.
