摘要
可编程并行接口芯片8255A是微机原理及应用课程内容之一。为了让学生理解、掌握并行接口的相关知识点。从认识教学目的、布置教学内容和安排课堂教学顺序等方面进行了探讨,针对选通输入输出方式这一教学难点,分析了其形成教学难点的原因;通过安排典型的教学案例使抽象的知识点具体化,以降低教学难度。
Programmable parallel interface chip 8255A is the teaching content of microcomputer principle and application course. Students could have a good understanding of parallel ports through the 8255A teaching, which would lay a foundation for engineering application in the future. The teaching goals, content and arrangements in class of 8255A are introduced. Aiming at difficulty of input/output mode, the cause is analyzed. By arranging for typical teaching cases, the abstract knowledge is made visual so that teaching difficulty may be reduced.
