Hi,
I'm trying to send an image to LCD_DATA pin ... not as easy as I though ....
I've used the tools bmptoraster to convert a 16 bit image to a header file ....
Looks like that the tools can't convert a 16 bit image, it has to be a 24 bit image <image format required 565/24>
After that I tried to take code from different place and I got :
/**
* \brief This function will configure the required clocks for LCDC instance.
*
* \return None.
*

what is wrong with that ? Why can't I see any signal going out ?
