[avr-gcc-list] sdram adress/length

[varsha]

 

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?

 

 

 

 

 

regards,
varsha
