Switching between LCD buffers in ADI_DEV_MODE_CHAINED_LOOPBACK

Hi ADI Support,

 

I am using an LCD connected to PPI with two buffers in ADI_DEV_MODE_CHAINED_LOOPBACK.

 

Now I have two Frame Buffers for the LCD. I would like to write e.g. an image to first buffer while the second is looped in chained mode to the LCD output. When the first image buffer is processed and ready I would like to write this buffer to the LCD output and update the image on the second buffer. I have noticed that it is not possible e.g. with switch to the other frame in the callback in the chained loopback mode.

 

adi_dev_Write(LcdDriverHandle,ADI_DEV_2D,&LCDOutputBuffer[1]);

 

Do you have any suggestions?

 

Thanks

 

Regards

Thomas
