Hi,
I want to use a 4-bit color scheme and also use the rotation of the screen orientation:
To have Y axis mirrored, X and Y swapped.
I used for rotation purpose parameter “GUIDRV_LIN_OSY_16” with the function “GUI_DEVICE_CreateAndLink”. It worked perfectly. But it is for 16-bit color depth.
But I need to use 4-bit color because I want to accommodate the whole GUI in the internal RAM of MCU.
While trying parameter “GUIDRV_LIN_OSY_4” I get compilation error “undefined reference to `GUIDRV_Lin_OSY_4_API'” and the app cannot be built.
What I’m doing wrong? – in the header “GUIDRV_Lin.h” there is a references to this parameter:
#define GUIDRV_LIN_OSY_4 &GUIDRV_Lin_OSY_4_API
as far as for all other color depths from 1 to 16 bits and rotations (OXY, OSY, OSX...)
With “GUIDRV_LIN_4” parameter I have no compiling error, but I need a display rotation with “OSY”.
Even in the SDK example for “LPCXpresso 54608” Board – “lpcxpresso54608_emwin_examples_emwin_touch_and_draw” – I have the same error with “GUIDRV_LIN_OSY_4”.
P.S.
I've just read in the "UM03001 User & Reference Guide for emWin V5.40" for "GUIDRV_Lin" driver Section:
.............................................
Each combination of orientation and color depth is possible. Please note that currently not all combinations are shipped with the driver.
If the required combination is not available, please send a request to obtain the required combination.
.............................................
Where I have to sent the request for 4-bit combination to?
Regards,
