Subject: | [avr-gcc-list] sdram adress/length |
Date: | Thu, 10 Nov 2005 13:07:26 +0530 |
hello all,
i am using avr-gcc (GCC) 3.4.3, and using ATmega16
,
and writng the code for copying sdram data int
flash, in c language.
There are three address bytes and three length
bytes for sdram.
At a time i can read 16 bytes from sdram, then i
want to decerment the length and incerement the address value bye
16.
how to increment address value(or decrement the
length), by using a single variable.
i dont want use three different bytes, because then
propogating carry becomes a problem..
is there any way , by which we can define a data
type which takes three bytes of memory...?
or how can i solve this problem?
