Hi,

My sdk : PROCESSOR_SDK_VISION_03_04_00_00

I use the Draw2D_drawBmp function to draw and then use Draw2D_clearBuf function clear buffer after delay 1 second.

Some points appear background color when switching

Here is the video :

Can you make sure cache is flushed after clearing buffer?

Hi,

How to check the cache?

Can you give me more detail?

by the way,

I modify the GrpxSrcLink_initAndDrawStaticBmp , replace DRAW2D_BMP_IDX_TI_LOGO to Mybmp ,

and add the cmd to clean draw 2d buffer.

Is this way feasible?

Hi,

Can you try with Draw2D_clearRegion( ) api and clear the entire region of your bmp.

I have found the issue, because I think the color 0X0000 is black, but after testing it is found to be through the first layer of the camera display
Q : If I need to draw a black color in GRPX, how should the color be set?

Hi,

Please check in draw2d module there should be such example.

Hi,

Can you tell me why RGB565 0x0000 is transparent?
I saw the place of drawpixel just for the color without special conversion.

Hi,

This is a very small module and has been developed for very minimal purpose.

So we have not tried and tested all combination of colors and other things.

You can give it a try itself for this color format and check whether you get the expected result or not.
