I made the mistake of telling the customer that I had the prototype working, and now they want four finished units by Wednesday !
You can't see it on the scope as the probe stops the oscillation anyway..
(They are non technical people and do not understand how difficult it is to give a time-line for R&D )
but moved the goalposts by asking if I could do it with a function that queues the incoming numbers.I said I could ,
I find that once I have a prototype running, I'm only about a third of the way done with the project.
