How big "delay_number"
PostPosted: Wed Sep 09, 2009 9:12 am     Reply with quote
Sorry bad english.
How big delay number can is?
delay_us(1500) is Ok.
delay_us(15000), is this OK??
Code:

#DEFINE number 1500
.
.
.
void clock_nyppy()
{
   viive=number;
   if(input(raja_cw) == 0) viive=number*10;
   pulssi_on;
   delay_us(viive);
   pulssi_off;
   delay_us(viive);
}

Its OK?

it depends on the PIC.

on an 18F (PCH compiler) delay_ms accepts a 8 bit variable. But is a constant is used then it can 16 bit constant.

Actually in version 4.xxx of the compiler, you can use either a constant
or a variable up to 16-bits. This works in PCM, PCH, etc.
From the manual:
Quote:

delay_us( )

Syntax: delay_us (time)
Parameters: time - a variable 0-65535(int16) or a constant 0-65535

-----------------------

delay_ms( )

Syntax: delay_ms (time)
Parameters: time - a variable 0-65535(int16) or a constant 0-65535
