资料介绍

逻辑笔是一种新颖的便携式电路检修工具,它能通过不同颜色的LED灯直接指示电平的状态,极大地方便了电子仪器设备的检修。本设计基于MSP430F149单片机,设计了一款可以对5V和3.3V两种CMOS逻辑电平进行精准检测的数字逻辑笔,同时,系统增设了电压测量功能。用户可通过键盘实现对判决电平的重新设置以及测量挡位的切换,检测结果与设置信息通过LED灯和液晶屏显示。因此,该系统在电路设计与调试以及仪器设备的检修维护领域有着良好的应用前景。

Logical pen is a new type portable circuit maintenance tool, it can directly indicate different electrical level states by different colors of LED, which greatly facilitates the maintenance of electronic equipment. Basing on MSP430F 149 microcontroller, we designed a digital logic pen which can detects 5V and 3.3V CMOS logic levels accurately. At the same time, the voltage measurement function is additionally included in the system.Using the keyboard, user can reset threshold voltage and shift gears. Detection result and setting information are displayed on the LED and LCD. The system has good application prospects in the fields of circuit design and debugging, equipment repair and maintenance.
