Hello,

we are using the emWin Library from NXP. It works very fine. For a new product we what to use the same uC / TFT. But how to change the orientation?
Currently we are using the following driver:

#define DISPLAY_DRIVER GUIDRV_LIN_1
#define COLOR_CONVERSION GUICC_1

The defines will not work
#define LCD_MIRROR_X 1
#define LCD_MIRROR_Y 1

I have found in the file GUIDRV_Lin.h
#define GUIDRV_LIN_OXY_1

I thought wunderful. I changed it to this driver. Unfortunately it isn't possible to build the project. I think the driver is not shipped with the NXP emLib.

The function GUI_SetOrientation() ist working. But ist needs to much performance.

So...wthat to do?

Best Regards

Daniel

Hi Sol,

we use the LPC1788 in the 144pin case. Due to the limited memory, we only work with 1 bit color depth.
The driver GUIDRV_LIN_1 works. But we want to rotate the display by 180 °.
We need the driver GUIDRV_LIN_OXY_1. Unfortunately, it is not possible to build the project. I think the driver is not shipped with the NXP emlib.

Us and probably many other users would help if NXP also implemented the full 1bit driver. With 8-bit color depth, a change of the display orientation is possible.

Can NXP provide us with a suitable driver?

Best Regards
Daniel
