Data manip. in memory

[MvanH]

I have to read and write data from and to a specific address in the memory.
I tried to use the search but could't find any answers.

I have a row of 512 16 bit signals written in the memory by another device that shares the same memory with my Proccesor.

Now I have to check and correct those 16 bit signals, but can't find out how I can read from the address were te signals are stored.
I think I kan use SprintF for writing to the memory, but I'm unsure of that (can't test it as my device is still in production)

Does anybody know how I can do this?

Thanks Martin

1. declare a unsigned short int pointer variable.
2, assign the starting address of the memory ( which you want to read) to that pointer variable.

Now you can put *pointerVariable and can see the value. If you want you can store it in an array. To see the next element, increment the pointerVariable by one.

unsigned short int c;
unsigned short int *p;
p = startingAddressOfMemory;
c = *p;
p++;
...
