				| problem to retrieve a image store in program memory |

				Compiler PCH v4.039 PIC18F66J60.
 
I store a large image which is defined
 
 	  | Code: | 	 		  | const char Imag[] = {0x00,0x01, ........}; | 	  
 
about 2000 element.
 
Code below can retrieve data in image correctly
 
 	  | Code: | 	 		  | memcpy(cData, Imag, wLen); | 	  
 
 
Since I need to access the image not just from the beginning
 
but code below cannot retrieve data in image correctly even if the addr is 0.
 
 	  | Code: | 	 		  | memcpy(cData, Imag + addr, wLen); | 	  
 
How can I access the data image ? Thanks in advance. |
