Hi All:
Can anyone explain the mechanism of lcdc double buffer?
To use lcdc double buffer, it needs to use two different regions to configure lcdc FBs. Then after enabling the lcdc, DMA takes turn to visiting the two buffers.Then I can not understand how to operate the two buffers. For example, now I need draw a rectangle on the screen , which buffer I shall use, and how to update the date to another?
Anyone can help me?
Thanks!
