- Hi There:
-
- How can I program the 8253 timer so that it generates an interrupt every
- 1/2 second, and then execute a particular function? I am using C language.
-
- Why I want to do this? I have an interactive type of program already written.
- There is something I want the program to do every 1/2 a second at the same time
- the program is doing something else. That is why I would like to set a timer
- to interrupt the program every 1/2 sec and then execute a particular function.
-
- With something like this, minimal modifications will have to be done to the
- original program (25,000 lines) and that is what I am looking for.
-
- Please let me know if you know how to do this using C (Borland C), or if you
- have some book references that I can use.
-
- Thanks in advance!
