摘要
主要阐述了基于ADV7125芯片的嵌入式系统的VGA接口设计方案。利用S3C2440处理器自带的LCD控制器来构造VGA时序,然后配合相应的控制信号,通过ADV7125硬件电路把S3C2440输出的LCD信号转换为标准的VGA信号输出。实验表明,该转换接口电路简单、可靠。
A design of VGA interface of the embedded system based on ADV7125 is proposed. The LCD controller of the S3C2440 pro cessor is used to construct the VGA timing. The LCD video signals are converted to VGA signals by the ADV7125 circuits with the cor responding control signal. This design has simple circuits and low cost. Experiments show that the VGA interface is simple and reliable .
