This tells you how to load a pointer to point to the memory address you want.

It took me 10 seconds to find this one - and I've haven't used Keil tools. For Keil compiler questions - go straight to the horse's mouth.


// this declares the buffer
xdata volatile unsigned char Buffer[100] _at_ 0x8000;

// this puts the address of the buffer into the pointer
xdata volatile unsigned char *ptrBuff = Buffer;


To store the byte:

*ptrBuff = value;

To read the byte:

value = *ptrBuff;

to increment the pointer to look at the next location:

ptrBuff++;

the read the value THEN increment the pointer:

value = *ptrBuff++;
