Hello
Project based on stm32u5g9 where I enabled TouchGfx in CubeMx settings. Layer 0 is configured to 800x600. I generate code from CubeMx. GPU2D and DMA2D are enabled and configured from CubeMx.
With TouchGfx Designer, I open the ApplicationTemplate.touchgfx.part generated or my ProjectName.touchgfx project, I see that screen dimensions are 800x480, I think it should be 800x600.
In TouchGfxDesigner, I add a screen and a box inside the screen, nothing more.
I generate code from TouchGfxDesigner.
In CubeIde, the only generated or added library I can see is :libtouchgfx-float-abi-hard.a.
I have other project generated by myself though directly from TouchGfxDesigner, chosing a STM32U5G9J-DK2 800x480 kit. Here I can see :libnemagfx-float-abi-hard.a and :libtouchgfxnema-float-abi-hard.a are included in CubeIde project.
In my code, I am trying to draw a scaled line, using ScalableImage, BitmapId, creating a dynamicBitmap.
Indeed the line is scaled and displayed in my display.
However the rendering time is very long, around 300 msec. I have defined RENDER_TIME_Pin, I can see the rendering time in oscilloscope.
Any help would be appreciated.
Regards.
