LTDC Window Horizontal Stop and Vertical Stop: 800 or 799?

[Ricko]

Hi,

when configuring the LTDC for a 800 x 800 display, the Window Horizontal Start is by default set to 0 which suggests it is a 0-indexed range. So do you set the Window Horizontal Stop and Window Vertical Stop to 800 or to 799?

As a separate question, if you use TouchGFX, are those values changed according to what you put on various pages and/or by some settings there?

Thank you :)

Hi @Ricko 

the vertical and horizontal stop should be 800 not 799.
I have played a lot with TouchGFX and always used like this .

here is one of my latest experiment with Google Nexus 7 inch display with 1280x800 resolution. 

The first screen is connected with ComAp's Inteli-compact NT over modbus RTU and my screen has more then 30 parameters , updating in real time. also the icons are changing colors as I programmed.

Here is TouchGFX running on Samsung Tab3 10.1" 1280x800 TFT. (STM32H745)

My custom designed board is similar as below.

If you need some guidance then don't hesitate.
