BT81x to support 1366*768 LCD?

<< < (2/2)

Hello John,

Yes that would be correct a quick run of the maths for a RGB565 image on a 1366*732 screen works out to roughly 2M Bytes. Such a bitmap would be too large for the internal graphics RAM on the BT81x. The BT81X ICs include support for external flash memory which can be used to store/offload graphics elements such as bitmaps, custom fonts and widgets from the integrated RAM, using ASTC:
You can find out more info at the following page (see programmers guide):

Is there a specific reason you are trying to use a full screen bitmap?

Best Regards,

The reason is that, there is a potential application to show a life video from cmos sensor. We wish to use a large display of 1366*768 to display it in full frame but don't know if it is possible. If not, we would be forced to use a LCD panel of lower resolution.
