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．
