Continual monitoring

[philrosenberg]

Hi everyone.
This is more an programming for windows/algorithm question rather than a code question, if any of you can help I'd be really greatful.

I'm trying to use a pc to monitor input and set output to the parrallel port. (for those of you that are interested I'm using a PICO interface to moniter a thermometer and turn a heater on and off to regulate temperature).
I have a library (that was supplied with the PICO) that includes a function get_value() that gets the input and set_value() that turns the output on and off.
How can I write a program to continually moniter the input without the program hanging. Is there any code I can use to beak a while loop when a message is sent to my program.

Cheers

Well my guess would be that you set up a timer to trigger once a second. The associated callback calls get_value() and set_value() once (as appropriate).

So once a second, you sample (and perhaps respond) to the temperature reading.

The rest of your win32 application carries on as it would normally.
