Pointer to int16
PostPosted: Mon Jul 13, 2009 5:38 am     Reply with quote
I'm having a problem with pointers to 16 bit variables.

var1 is a RAM address, say 0x0800
var2 is the data that I would like to store at that address.

If I do this:
Code:
*var1=var2;
I lose the MS byte of my data.

If I do this, however, I get the desired result.
Code:
*var1=var2;
var1++;
*var1=var2>>8;


My question: is there a 'smarter' way to do this? Have I not read the manual fully? Embarassed

var1 and var2 are declared as int16.
I'm using PCD for a dsPIC30F2010.

Thanks.
Rohit

Whoops! I should've declared var1 as int16*. This is what happens if you sit for 12 hours straight looking at piles of C Rolling Eyes
