Abstract：If single chip micro computer controls light-emitting diode (LED), it needs abundant peripheral resources, but in this way, it is not convenient to be expanded, modified and maintained. In order to overcome these shortcomings, field programmable gate array (FPGA) is used to control LED. The hardware design uses low power consumption and high performance device EP1C6Q240C8. Quartus II is the software development environment. There are three modules built under the software development environment: divided clock module, word stock module and LED dot matrix display module, and these independent modules are connected to be a whole system. Finally, 32×64 dot matrix display is realized successfully. It is convenient for the customer to adjust the three independent modules according to actual demands and it is easier to realize online updation.
