How to introduce Delay in QG8

Sandeepsharma — Thu, 30 Aug 2007 11:35:52 GMT

Hi,

I am using QG8 demo board, and want to introduce some know value of delay between two instructions.

i.e. 5 sec or 5 min. So how to calculate and introduce in my program.

Sandeep,

There are various ways of creating a delay like that.

One of them is to use the RTI clock in the 9S08QG.

It has a 1 KHz source and can be divided down by 200 to get a 5 Hz interrupt signal.

I have included software, that I have not tested, but tell me if it does not work.

Regards,

Ake

Hello Sandeep,

The following thread provides discussion in the context of providing switch de-bounce delays, but might also be relevant to your problem.

If you would perfer assembly language you could look at the software from this project that uses various delay subroutines.
