摘要
系统是以TI公司的超低功耗MCU MSP430为核心,利用光敏二极管排列成矩阵对摄像头采集点光源在液晶屏所成的像进行采样,经过单片机运算后适时的调整和控制步进电机来实现工作台X/Y方向移动,以达到精确定位的目的。经过实际的参数的测试和分析,验证了系统的可行性和有效性。
A point source from the camera LCD screen is captured using Photodiodes arranged in a matrix into the image of the sample in this design system taking ultralow-power MCU MSP430.The stepper motor is adjusted timely and controlled to achieve the table X/Y direction in order to achieve the purpose of precise positioning after the microcontroller operation.After the actual test and analysis of parameters,the feasibility and effectiveness of the system is verified.
