change Vsync

[saeed taherianfard]

Hi

I'm using stm32f429 and my question is about LTDC peripheral.

Is there any way to change VSYNC unit from "Line" to "pixel"?(Like Hsync unit that is in pixel)

Thanks

Thank You

Can i generate it manually?(A signal synchronized with LCD_CLK that toggled at vertical blanking).

@saeed taherianfard​  please tag me if you find out how to do this.

Im facing an issue with an ILI9488 in landscape mode where a 1/3 of the display is not showing correctly and as soon as I move the display from external clock to internal clock it works with no issue

320(RGB) x 480 Resolution is portrait type controller, @DResn.1​ you need clock it and manage data in portrait mode.

@saeed taherianfard​ you cant change standart, you need locate your trouble source. VSYNC is timed pulse to manage synchronized frames for show.

In princip is irelevant how wide this pulse is, only need be in range between min and max. When you use VSYNC 1 then you timed it as Npx, where N is sum HSYNC+HACTIVE+...
