Hello, Sorry to be a nuisance but I'm afraid I'm a little stuck. I need to sample 12v signals with a PIC uC. I'm not an engineer nor do I pretend to be, and if I don't know the answer, or how to find it I ask :)
Anyway, I'll tell you the reason I need to do this. I need to decode stepper motor phases. I've already written most of the firmware for the uC, and I know how to implement the rest of the device bar this 12v matter. It's a one-off thing for my own interest (initially anyway) so the simpler the better. by simpler I mean cheaper.
Any help with this would be greatly appreciated. Thankyou in advance to all those that do.
Tristan.
