面向学科竞赛的单片机开发板及检测系统设计

摘要

This paper introduces a kind of discipline competition oriented microcontroller development board and the detection system design, This development board with C8051F020 chip as the core, has eight digital tube display output、128*64 LCD output、16 key input、four road, 12 high-speed AD input、two road, 12 DA output、44 external IO interface resource. When the development board can not download properly or the commonly used features can not be normal use, detection system can detect, timely troubleshooting.%文章介绍了一种面向学科竞赛的单片机开发板及检测系统设计，本开发板以C8051F020芯片为核心，具有8位数码管显示输出，128*64液晶显示输出，16位按键输入，四路12位高速AD输入，二路12位DA输出，44个外部引出IO接口等资源。当开发板不能正常下载或者各常用功能部件不能正常使用时，检测系统可以进行检测，及时排除故障。
