摘要
在关于视觉诱发脑电信号的采集中,需要用闪光灯以不同频率、适当亮度的灯光刺激被测试者的眼睛,针对这一需要,设计了一种新型的基于Atmega8单片机控制驱动LED发光的视觉诱发电位刺激器,分析了具体的设计方案选择、硬件电路的设计和软件的设计,并最终实现了符合医用标准的视觉诱发电位刺激器.
In the acquisition of visual evoked EEG,a flash needs to be used to stimulate the tester＇s eyes at different frequencies and appropriate light intensity.Aiming at this need,it designed a new type of visual evoked potential flash stimulator based on Atmega8 single-chip microcomputer driving LEDs,and analyzed the specific design scheme selection,hardware circuit design,software design.The stimulator complies with medical standards.
