【摘要】 传统的显示用LED驱动器通常采用速度较高的数据传输协议,而柔性LED显示系统的数据线通常要长距离传输。为了解决这个矛盾,可以使用DMX512协议进行长距离传输,并在柔性LED灯带的端口处增加一个协议转换芯片。利用FPGA芯片实现了一个应用于柔性LED驱动器的DMX512协议转换芯片,并完成了实际系统的测试工作,协议转换速度符合协议的最高速度,有很强的实际应用价值。更多还原

【Abstract】 The traditional display LED drive usually adopts high-speed data transfer protocol,whereas the flexible LED display system needs long transfer distance.In order to eliminate this contradiction,DMX512 protocol can be used for long distance transmission,and a protocol converter IC need to be added to the port of flexible LED lights as well.In this paper,a DMX512 protocol converter IC was designed and implemented with FPGA for the flexible LED display.The test of the actual IC was done as well,and the speed met the highest speed requirement of the protocol.A very practical application of the IC is shown..更多还原
