 -1 Answer is Wrong		 #166081 - DELAY_0.1.ZIP Useful?
Responding to: Sandeep Gupta's previous message
Hi Sandeep,

Have a look at the DELAY_0.1 module available free from my website:

http://members.iinet.net.au/~vanluynm/

Most would agree that for-loop generated delays are of limited use, but I think you may find this module useful in your current circumstance.

You can instantiate a moderately accurate delay with a simple subroutine call like:

delay_ms(25);

All the timing calculations are done for you, and thanks to the assistance of some very knowledgeable 8052.com members, you should have no problems with compiler optimizations, etc.

Regards,
Murray R. Van Luyn.
