Quick question on delay_ms
PostPosted: Mon Jun 02, 2008 10:11 pm     Reply with quote
I'm using this delay(delay_ms(3000) )in my routine. When in a delay, the rda interrupt does not seem to work. It works fine outside the delay, but it seems to disable interrupts. I have been reading the CCS manual, and it sounds like it should just increase the time of the delay. Extended to service interrupt.

my rda interrupt:

Code:
#int_rda
void serial_isr()
{
   int t;

   buffer[next_in]=getc();
   if(buffer[next_in]==':')
   {
   bufferloaded = 1;
   bufmax = next_in;
   }
   
   t=next_in;
   next_in=(next_in+1) % BUFFER_SIZE;
   if(next_in==next_out)
     next_in=t;           // Buffer full !!
}

Do you have any other interrupt routines in which you are using delays ?

What PIC are you using ?

Make sure that compiler warnings are enabled. Do you get any warnings
when you compile the code.
