Unsigned long problem
PostPosted: Fri Oct 22, 2004 10:42 am     Reply with quote
Hello I have a problem
Why if I write :

unsigned long appoggio;

T2cal = 8291;

appoggio = T2cal * 180L ;
printf ("X %08lu ", appoggio ) ;

in serial I read 00052568

What is the problem?
Thank in advance..
Chas

Longs in CCS C are 16 bits which limits them to 65535. So you are experiencing some sort of truncation in the arithematic. You will need to use int32 for you variables.
