Hello!
I use STM32F429IGT and I have an LCD with SDRAM, that? I thought, was correctly configured. But now I guess, something is wrong because one function - GUI_MEMDEV_ROTATE - does nothing when called. All other functions work correctly.
For example i try to use that code (exactly document UM03001.pdf (emWin User Guide and Reference Manual), page 368):
GUI_MEMDEV_Handle hMemSource;
GUI_MEMDEV_Handle hMemDest;
GUI_RECT RectSource = {0, 0, 69, 39};
GUI_RECT RectDest = {0, 0, 79, 79};
hMemSource = GUI_MEMDEV_CreateFixed(RectSource.x0, RectSource.y0,
RectSource.x1 - RectSource.x0 + 1,
RectSource.y1 - RectSource.y0 + 1,
GUI_MEMDEV_NOTRANS,
GUI_MEMDEV_APILIST_32, GUI_COLOR_CONV_888);
hMemDest = GUI_MEMDEV_CreateFixed(RectDest.x0, RectDest.y0,
RectDest.x1 - RectDest.x0 + 1,
RectDest.y1 - RectDest.y0 + 1,
GUI_MEMDEV_NOTRANS,
GUI_MEMDEV_APILIST_32, GUI_COLOR_CONV_888);
GUI_MEMDEV_Select(hMemSource);
GUI_DrawGradientV(RectSource.x0, RectSource.y0,
RectSource.x1, RectSource.y1,
GUI_WHITE, GUI_DARKGREEN);
GUI_SetColor(GUI_BLUE);
GUI_SetFont(&GUI_Font20B_ASCII);
GUI_SetTextMode(GUI_TM_TRANS);
GUI_DispStringInRect("emWin", &RectSource, GUI_TA_HCENTER | GUI_TA_VCENTER);
GUI_DrawRect(0, 0, RectSource.x1, RectSource.y1);
GUI_MEMDEV_Select(hMemDest);
GUI_Clear();
GUI_MEMDEV_Select(0);
GUI_MEMDEV_RotateHQ(hMemSource, hMemDest,
(RectDest.x1 - RectSource.x1) / 2,
(RectDest.y1 - RectSource.y1) / 2,
30 * 1000,
1000);
GUI_MEMDEV_CopyToLCDAt(hMemSource, 10, (RectDest.y1 - RectSource.y1) / 2);
GUI_MEMDEV_CopyToLCDAt(hMemDest, 100, 0);That is what I expect to see:
But I see only the first, non rotated part of image.
I use STM32CubeMX 4.2.7.0 and IAR Embedded Workbench 7.50.2.10505 as IDE
What can be the reason of such malfunction?
Thank you!
