Hello,
I found a workaround for the double redraw issue and thought I would share.
I'm working on an STM32L4 MCU running FreeRTOS.
My workaround basically consist in modifying the guiShowPage function this way:
void guiShowPage(unsigned pageIndex)
{
// Hide all pages
gwinHide( page1 );
gwinHide( page2 );
gwinHide( page3 );
/* ... */
// Allow the rendering thread to clear the screen
gfxYield(); // ADD THIS LINE!
// Show page selected page
switch ( pageIndex ) {
case 0:
gwinRaise( page1 ); // ADD THIS LINE!
gwinShow( page1 );
break;
case 1:
gwinRaise( page2 ); // ADD THIS LINE!
gwinShow( page2 );
break;
/* ... */
default:
break;
}
}
I hope this will help someone else in the future
