摘要
本文设计了一种基于FPGA的大屏幕LED控制器,PC通过串口将显示的数据传送到FPGA的内部,在内部使用RAM模块进行存储,内部通过控制模块将数据输出,通过电源转化芯片74HC245,将3.3V的电压转化为5V,与外部显示模块连接。采用verilog语言进行设计,在ALTERA EP2C35的综合主频达到160.6Mhz。
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.
