Hello, i am using the AT T89C51CC01 and due to the size a put some static variables in the flash ( i.e. unsigned char code variable[100][100]=...) Some of these variables are just for configuration. I know that i can program just some parts of the flash with a c driver found on the atmel page. I need to know the startaddress of these variables. Do I have to get the information from the Keil linker file (which would be only a small program, since there is already a windows config tool for data communication with my project) or can i also get the information during runtime? How do i handle that? I am not interested in giving out the source code of the final project at the end, but i will try, that everyone can configure it to its needs, so thats the cause why i cannot just recompile the source with new data. Thank you in advance Axel
