Delay_us() variable greater than 255?

[eyewonder300]

My code needs to make calculations for delays that are more than the 255 allowed when using a variable.

Is there any (easy) way to have my program make the calculation, then have that multi-thousand uSec delay?

Cheers,

I'm not sure what you're asking for. Do you have an older version of the
compiler (vs. 3.xxx) that doesn't support variable delays larger than 255,
and you need a work-around ? Or, are you asking for some way to
convert usec delays into milliseconds ? Are you asking for some
alternative delay method ?

[Douglas Kennedy]

Use two variables one under 255 for the delay and the other to control the number of times delay is called from within a loop.
Alternatively delay will take a constant bigger than 255 so if you can accept a certain graininess use one big delay several times in your loop.

The compiler I am using is 4.069. I have been using an old manual that says the range of a variable that could be passed is 0-255, and that a constant could be up to 65535.

What my code does is calculate a delay - ex 6666uSec, in an int16 variable 'new_delay'. What I want is to be able to do is have the program make that calculation, then execute a 'delay_us(new_delay)' for a 6,666uSec delay.

I did not try that, as my old manual indicated that it would not work.

Does my current compiler do what I want?

Thanks,

Steve

Compiler vs. 4.069 was released on about March 3, 2008.
You could use the June 2008 manual:
http://www-pagines.fib.upc.es/~sdmi/pdfs/Manual_CCS.pdf
But hyperlinks don't work in that one, so it's not fun to use.

You could use the June 2010 manual:

Thanks, PCM et al. Looking at a much newer manual told me that I could do exactly what I wanted.
