摘要
VxWorks操作系统中的图形开发组件WindML只提供CHIPS芯片的通用驱动支持,没有针对CHIPS65545显示芯片的具体驱动程序。因此提出一种基于PowerPC嵌入式平台使用CHIPS65545显示芯片的WindML图形驱动设计方法。介绍基于PowerPC嵌入式平台,利用VxWorks操作系统下的图形开发组件WindML开发基于CHIPS65545显示芯片的显卡驱动,并给出了详细的开发步骤。实验结果表明:该程序工作正常,分辨率可达1 024×768,刷新率60 Hz,最高支持8bpp颜色深度,在实际工作中运用情况良好。
The graphics development component WindML in VxWorks operating system only provide CHIPS chip with generic driver support, there is no specific driver program for CHIPS 65445 display chip. Therefore, this article proposed one method which using WindML graphics drive design method of CHIPS65545 chip based on the PowerPC embedded platform. Based on PowerPC embedded platform, use WindML operation system graphics development component in VxWorks operating system to develop display driver based on CHIP65545 chip, and give the detailed steps of development. The experimental results show that the program is working correctly, the resolution can reach 1 024~768, refresh rate is 60Hz, the highest support reaches 8bpp color depth. It runs smoothly in application.
