STemWin with ILI9341 Graphic problem

[voyvoda .]

Hello,

I have made an STemWin example with STM32F407 and ILI9341 with SPI interface.

I think that there is an graphic driver problem. The graphics are not sharp. What Could be the correct driver settings ?

My settings are;

pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_565, 0, 0);

GUIDRV_FlexColor_SetFunc(pDevice, &PortAPI, GUIDRV_FLEXCOLOR_F66709, GUIDRV_FLEXCOLOR_M16C0B8);

Looks more like power supply problem.

I am supplying the LCD via 5V. There is no problem with the supply.

I resolved my issue by using the code line below

pDevice = GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_M565, 0, 0);
