Hi All,
Recently, i have testing memory device Because of the flickering.
I've attached my application test code below.
My hardware is stm32f767IGT6 with SDRAM using FMC.
I have two png file to display in 320x240 LCD.
Because of the flickering, I'd like to use MEMDEV or MULTIBUF.
First i tried to use Multi Buf. but it's not works with hardfault So, i'm trying to use MEMDEV.
The test code has 2 images.
In MainTask,
If the "test" is true, the smile guy is displayed properly.
but "test" is false, sysytem crush, with hardfault()
Of course if not using MEMDEV, displayed properly.
void MainTask(void)
{
GUI_MEMDEV_Handle hMem = GUI_MEMDEV_Create(0, 0, 320, 240);
GUI_MEMDEV_Select(hMem);
GUI_Clear();
if(test)
{
GUI_PNG_Draw(_acBitmap_50x50, sizeof(_acPNG), 0, 0);
}
else
{
GUI_PNG_Draw(background, sizeof(background), 0, 0);
}
}
GUI_MEMDEV_CopyToLCD(hMem);
while (1)
{
GUI_Delay(100);
}
}
What am i doing wrong?
