Dear Sir,
Thanks soooooooo much for the right example what i was looking for. I would request you, if you dont feel botheration, can you give me some more Keil C code examples, like , showing me a sample small function that fethes lookup table data from an external memory.

Moreover, how can I store the lookup table in that piece of memory ? Should I have to burn that memory ic seperately with the lookup table ? if so, how can I make the hex file for that memory ? Is there any C code you have which can store data to a flash memory and later on to be compiled to HEX by Keil C51 compiler ?

IS there any details article available at you about this kind of projects ?

Thanks and regards,
Emran
