STM32H7B3 GFX Resolution Supports and Frame Buffer Calculation:

[Karan 123]

Hello,

STM32H7B3xI is coming with approx . 1.4MB Internal RAM .

What max TFT resolution it will supports with Internal Frame Buffer (Single Buffer)

only with single MCU?

Frame Buffer = Number of Pixels x ( Color Depth in Bits / 8 ) 

Frame Buffer = 800 x 480 x ( 16/ 8 ) 

Frame Buffer = 768000 Bytes

Frame Buffer = 750 KBytes

Theoretically, you can do the calculations, but you also need to consider the complexity of the application vs the "Max Resolution".

Thanks..

​

​​Ok..

​

My Application has Scroll Lists, Text Areas, Buttons with Multiple Screens.. No Video No Heavy Graphics and No Animations Required. Just for Industrial HMIs.

​

1) How to Distinguish RAM from

Fram Buffer and Rest of RAM for application part.

​

​

2)​ Is there any Eval/Development that have 7 inch TFT 800 x 480 ResolutionResolution with RGB Interface?
