Abstract: 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.
