nuGfxSetCfb
Formatvoid nuGfxSetCfb(u16** framebuf, u32 framebufnum)
Arguments
- framebuf is the pointer to the frame buffer pointer arrays
- framebufnum is the frame buffer number
none
What This Function Does
It registers the frame buffers. It registers the frame buffer's RDRAM address arrays. The default with the nuGfxInit function is registration of three frame buffer pointer arrays as a triple frame buffer with low resolution (320x240 dot), 16-bit color pixels as follows:
u16* FrameBuf[3] = {
(u16*)NU_GFXFRAMEBUFFER0_ADDR,
(u16*)NU_GFXFRAMEBUFFER1_ADDR,
(u16*)NU_GFXFRAMEBUFFER2_ADDR,
} ;
When you need to change the frame buffer pointer array or create an initializer function that is independent of the nuGfxInit function, use the nuGfxSetCfb function to register the frame buffer pointer. The pointer array registered with this function is used internally by the Graphics Task Manager.
Example
/* frame buffer pointer array */
u16* FrameBuf[3] = {
(u16*)NU_GFXFRAMEBUFFER0_ADDR,
(u16*)NU_GFXFRAMEBUFFER1_ADDR,
(u16*)NU_GFXFRAMEBUFFER2_ADDR,
} ;
/* register frame buffer */
void gfxSetCfb(FrameBuf, 3);
.......
}
