基于摄像头及单片机逻辑芯片检测器设计

Design of Logic Chip Detector Based on Camera and MCU

为解决集成逻辑芯片功能检测繁琐,效率低等问题,设计一种以STC15系列单片机和OpenMV摄像头为核心模块的数字集成逻辑芯片快速检测器。由摄像头读取芯片标识符识别出芯片型号,并通过串口发送给单片机,单片机根据被测芯片型号产生逻辑测试信号和读取被测芯片的输出端信号,从而判别芯片功能是否正常,具有结构简单、检测速度快、操作方便、成本低等特点。

In order to solve the problem of complex and low efficiency of integrated logic chip function detection,a fast detector of digital integrated logic chip is designed based on STC15 series MCU and OpenMV camera as the core module.And that camera reads the identifier of the chip to identify the model of the chip and sends the model to the MCU through a serial port,and the MCU generates a logic test signal and reads an output end signal of the tested chip according to the model of the tested chip so as to judge whether the function of the tested chip is normal or not.It has the characteristics of simple structure,high detection speed,convenient operation,low cost and the like.
