#bit directive not working
PostPosted: Thu Feb 15, 2007 2:09 pm     Reply with quote
Compiler: PCWH 4.024
Part #: PIC16F913
Oscillator: 20MHZ

Why when I try to use the #bit directive multiple times inside a function, the compiler gives me the error "A numeric expression must appear here".
Code:

   int ch;
   #bit ch_0 = ch.0;
   #bit ch_1 = ch.1;
   #bit ch_2 = ch.2;
   #bit ch_3 = ch.3;
   #bit ch_4 = ch.4;
   #bit ch_5 = ch.5;
   #bit ch_6 = ch.6;
   #bit ch_7 = ch.7;


if I only use one #bit it does not complain
Code:

   int ch;
   #bit ch_0 = ch.0;
/*   #bit ch_1 = ch.1;
   #bit ch_2 = ch.2;
   #bit ch_3 = ch.3;
   #bit ch_4 = ch.4;
   #bit ch_5 = ch.5;
   #bit ch_6 = ch.6;
   #bit ch_7 = ch.7;
*/

Actually, it will give an error for that one too.

Download the CCS compiler manual.

Look in the section on the #bit directive.

Does CCS show anything at the end of the line on a #bit declaration ?
What character do you have at the end ?

I must have stared at the manual for a half an hour before I wrote this post... can't believe I didn't see there wasn't a semi-colon.

Thanks
