My LPC1788 board works fine in 1bpp palette mode on attached display.
Pictures are getting displayed with two predefined palette colors when copying emWin generated bitmap from flash to _aVRAM.
When implementing emWin libraries to display same picture, I am either getting hard faults or my display just shows first palette color full screen:
GUI_Init();
GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), &_cbDialog, 0, 0, 0);
Please answer/confirm:
1. What emWin display driver is required? GUIDRV_Lin_1_API?
2. What color conversion setting is required? GUICC_0?
3. Do I need to set my palette data through LCD_SetLUTEntryEx() or some other function?
4. Will 8k be sufficient for emWin to simply display a 1bpp bitmap? (additional frame buffer for LPC display controller)
Thanks a lot for your replies in advance.
