Upgrade from SSP1.7.8 to SSP2.1.0 - Display performance problems

Chris

He Guys

i updated one projects from SSP Version 1.7.8 to 2.1.0 to stay on the same version with our other projects.

Upgrade SSP from 1.7.8 to 2.1.0

Guix Studio 5.6.1.0 to 6.1.9.2

i  use for the project a 800 x 480 pixel display with 180° screen rotation angle on a S7G2 uc with a 32mbyte sdram.
At SSP1.7.8 i could rotated the Display in the configuration settings at SSP 2.1.0 its not possible anymore.
So i tried to rotated the Display at the GUIX Settings and there ist the issue.

if i am using the SSP 2.1.0 with the GUIX 6.1.9.2 with rotated Display i have performance issues. if i scroll down a vertical list its lagging.

if i am using the SSP 2.1.0 with GUIX 6.1.9.2 with not rotated Display everything is working fine.

I tried to incrase the frame buffer and the work buffer, it dosnt help.

i will attach you settings pictures from guix and the configuration file.

SSP 1.7.8 + GUIX Settings

  

SSP 2.1.0 + GUIX Settings

What i am missing ???

Thanks in advance for any soloution to fix the problem

    Ok i find  a introduction to flip the window :

    https://synergygallery.renesas.com/media/products/1/403/en-US/r11an0507eu0101-synergy-migration-ssp200.pdf

    if i set "allocate canvas memory " at the Guix settings i have this error:

    Its looks like Guix dosnt understand to use the sdram for the buffer....

    I think there is an error in the document you refered to, it should not show "Allocate canvas memory" as checked in the GUIX studio project, it should show :-

    as the setting in the SSP project :-

    will allocate a GUIX canvas buffer in the correct section (i.e. .sdram in this case) :-

    I don't know about the perfromance issue you are seeing, when you migrate to SSP 2.1.0 however.

    It looks like nobody can help me. I will use the SSP 1.7.8 for now.

    Hello Chris, 

    Did you find an answer to your question? I Also have to move from ssp 1.2.1 to ssp 2.0.0 or later and i also get a performance issue with a 180° screen rotation.

    Also I do have to handle 2 types of screen orientation, is it possible with a flag to handle the screen rotation as it was before 1.7.8?

    Thanks.

    Hello Matthieu,

    i cant remember what i changed at all but here some points:-

    As you can see, i had some problems with scrolling at vertical list.

    • i reduced the Update Hz at the touch panel framework
    • at my lcd thread i reduced to call gx_system_event_send(&g_gx_event) 

    But i never got the same performance like SSP1.7.8. I hope u can improve your performance issues if you find something out, let me know.

    Thanks 

    Chris
