DMA2D Interface
DMA2D Features
- fill specific color
Fill part or all of the target image with a specific color
- mem to mem copy
Copy part or all of the source image to part or all of the target image
- mem to mem with pixel conversion
Copy part or all of the source image to part or all of the target image through pixel format conversion
