_________________________________________________________________________________________________
unsigned int GFX_Set_Src_Ptr(unsigned int src_ptr);
unsigned int GFX_Set_Dest_Ptr(unsigned int dest_ptr);
int GFX_Get_Tilemap_Width(void);
Read the source pointer and add 4 to it and write it back.
Read the destination pointer and add 4 to it and write it back.
Read the tilemap width and store it.
GFX_Set_Src_Ptr(…) sets the 16-bit source pointer for tile GPU fill and memory operations. This is an
absolute address in Propeller RAM memory. Returns 1.
GFX_Set_Dest_Ptr(…) sets the 16-bit destination pointer for tile GPU fill and memory operations. This is
an absolute address in Propeller RAM memory. Returns 1.
GFX_Get_Tilemap_Width() retrieves the 8-bit the tile map width encoded as 0,1,2,3 which means (32,
64, 128, 256) tiles.
