Hello All,
After updated the middleware from 7.0.0 to 7.1.0, the GUI is not working, but others(USB, file system) are working well. Can I only update the USB and file system and remain the old GUI?
Can you please detail "...the GUI is not working..." in order to better understand the current situation, thx
The GUI procedure is as follows:
(1) Call GUI_Init (2) Call GUI_DrawBitmap to draw a splash image (3) After 5s, create a dialog with a couple of widgets ...
After updated the middleware, the LCD screen would stay in the splash image and not go on. while the previous middleware has no this issue.
Now I have an workaround, call GUI_SelectLayer (0) before creating the dialog, and then everything is OK.
But actually, I don't fully know why? Isn't the default selected layer 0 in new middleware?
Thanks for these details.
Segger demonstrates the usage i.e. at: www.segger.com/emwin-multi-layer-multi-display-support.html
But to figure this out in detail with a focus in the middleware versions please open a support-ticket and attach your compressed project: www2.keil.com/.../silver
