Good call and thank you, but host software is not an option. If so, believe me, it would have been complete very soon after seeing the requirement. The system controls a complex factory robot controlling system and the engineer on that end will not let us install any software (but he doesn't mind us poking around with the hardware... whatever!). The first three characters will have to be detected and will be constant. The last four will change and be alphanumeric, and will need to be sent to the other end for control reasons.
I understand that the coding will be complex. Just need to know how to setup a comparator for this kind of thing so I can start coding. It is amazing at how little is available about the comparator. There is a lot out there that talks about the comparator, and Melanie has a great posting on setting it up in PicBasic, but nothing on what wire goes where, how to setup the timer and how that connects to the comparator or any other detail for someone to get started. I've used in some way or another quite a bit of different functions on the PIC - just not the comparator.
These are my search results so far:
Google -nothing but references to Microchip and this forum.
This forum -only morsels in bits and pieces with one good post on the very basics by Melanie.
Microchip -20 ways to configure a comaparator for anything I don't need to do.
Thanks again.
