我国大专院校开设的微机原理课程,一般都使用TP801单板机作为实验工具,但与其配套使用的TP80TS实验板或A/D转换板的价格要千元左右。由于经费有限,很多学校的实验内容往往仅局限于TP801单板机本身之上,因而使学生不能吃透和掌握该门课程的要旨。笔者在教学实践中,制作了几套与TP801单板机配套使用的实验电 China’s universities and colleges opened the microcomputer principle courses, generally use the TP801 single-board machine as an experimental tool, but with its supporting the use of the TP80TS experimental board or A / D conversion board to the price of around thousand. Due to limited funding, the experimental content of many schools is often confined to the TP801 single-board machine itself, thus preventing students from having a thorough understanding of the essence of the course. In the teaching practice, I made several experiments with the TP801 single board machine supporting the use of experiments
