摘要

This paper provides a parameter controllable visual evoked potential stimulator device for brain-computer interface, which can generate multichannel linear frequency modulation signal in real time. The device consists of host computer, FPGA board and LED board. Based on the data from GUI, FPGA generates multichannel signal synchronously with direct digital synthesis technique. The controllable parameters include frequency, color, luminance, duty cycle and last-rest time. Their effective ranges all conform to the requirements. The experiment results show that the output of the presented stimulator is stable, precise and effective, providing the ability to serve the brain-computer interface study well.
