Changing #define

Hello,

In programme I have defined

#define DEVICE_ID 0x32

But I want to change Device Id when I get command of change Device Address.

How should I do it?

This is standard, textbook 'C' - nothing specifically to do with the 8051 or Keil.

#define gives a definition that is fixed at compile time;

IF you want it to be changeable at run time, you will need to use a variable.

 RE: Changing #define

u cant do it like that
coz DEVICE_ID is replaced by 0x32 where ever u hve written it by compiler
if u wana assign DEVICE_ID different Values that declear it as variable in user program
not in this way
