I need a PIC programmed to detect and count pulses and then send the result out one pin serially that will be hooked to another microcontroller.
The microcontroller I have now is a basic atom 24-pin pro and since it isn't multitasking, I can't have it pausing the whole program to check for pulses. The pulses are coming from a vehicle speed sensor at 4000 pulses/mile which is about 1.11 pulse per mph. Anyway, all I need the "backup" pic to do is send the number of pulses per second serially to the other microcontroller where it will figure out the speed.
I do not know which PIC would be best for this but it would need to be fast enough to deliver the results every second. Also, if it is possible, maybe have one pin outputting the results every half second and one pin outputting every second so I could decide which one I wanted to use. With one whole second, it would be more accurate for lower speeds but it wouldn't be as 'real time' as I want it to be so I may just choose the half-second pin so that it is faster but less accurate at low speeds.
I will need someone with just a little experience with various kinds of PICs and basic programming knowledge. This should be a very easy project but I don't have the equipment and I don't want to invest in it just for this one project.
## Deliverables
1) PIC programmed and ready to go with schematics of how to hook it up. Payment will be released when code is finished and I can look at it, not when I receive the chip.
2) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
3) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):
a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.
b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
4) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
