Can you send the whole runnable project (or small demonstration project)?
It's bit difficult to get the proper picture from that. Missing
declarations, etc.
I didn't quite understand why you rejected model based on Sport_read()
event..?

> I removed the Sport_read by creating an idle event (with a timer event
