I would like to know what is meant by a physical address (let say a LCD display at address 0x8000) and how can I access the device. Is it just the chip select that is hardwired to that address? Then how is the compiler working ? Also I have tried to access a RAM (external RAM) but does not work. My program works fine with internal RAM, is it just a compiler setting (uvision2). I have tried with the PRAGMA LARGE but no success. Thanks for help
