The Research and Design of LED Controller Based on FPGA

In this paper design a LED Display Screen controller based on FPGA.The PC send the data to FPGA with serial interface,and the data is store in the RAM of FPGA.The internal module controll the data and make it display in the LED screen.74HC245 converted the IO volte from 3.3V to 5V and the pin can connect with the display module finally.The design in FPGA is discripted with verilog,and the max frequency is 160.06 Mhz which is synthesized on Altera EP2C35.
