GX_LoadOBJ

C Specification

#include <nitro/gx/gx_load.h>
void GX_LoadOBJ(const void *pSrc, u32 offset, u32 szByte);

Arguments

pSrc Pointer to transfer origin
offset Offset
szByte Transfer size (in bytes)

Return Values

None.

Description

This function uses DMA to transfer standard OBJ data to the Main 2D Engine OBJ-VRAM. An offset can be specified for the transfer destination address. The DMA channel that is used is GX_DMAID (defined in gxcommon.h). The transfer destination address is HW_OBJ_VRAM in the ARM9 memory space + offset. Both offset and szByte must be multiples of 4.

Notes: Because the DMA transfer is carried out internally, the transfer source data must be flushed to the main memory using a function such as DC_FlushRange prior to the process. If the regions for transfer source and transfer destination overlap, the operation result is not guaranteed.
