Variable declaration for timer 1
PostPosted: Tue Apr 11, 2006 4:16 pm     Reply with quote
The following code seems to revert to signed int16 when printing out the variable "value". This also happens when I use unsigned long int. The only way I can get it to work is to declare "value" as unsigned int32. Any idea why this is happening?
Code:
#include <16F877.H>
#fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 20000000)
#use RS232(BAUD=38400,XMIT=PIN_C6,RCV=PIN_C7)


main()
{
 unsigned int16 value;
 setup_timer_1(T1_INTERNAL);
 while (1)
 {
  value = get_timer1();
  printf("\n\rTimer 1 = %ld ", value);
 }
}

Look in the CCS manual, in the printf() section. Look at the list
of format specifiers. Use the one for "long unsigned int".

Thanks for another piece to the puzzle, Harry.
