I need some help...
Im working on this simulator project for work. I need to measure a percentage on signal that is coming out of this one panel. We have a card on the system that can measure the pulse width but we are waiting on the software for it. and we still have another week or so to go.
My plan is to use a PIC (877A PWM capture mode) to measure the 'percent on' of this signal, convert it to an analog value (Via R-R/2 D/A converter) and put that on one of the 'analog in' signals. Then do some conversions in my plant models to get the percentage on.
(It is a 100 Hz signal btw)
Normally I would research this myself, but Im limited on time. I need to measure this signal asap, this is pretty much the only road block Im facing right now.
Anyone ever use this PWM capture before? I would greatly appreciate anyone's help, since I just started learning PICs just alittle bit ago.
Thanks
