I am attempting to build the brake light flasher circuit found here: http://www.electro-tech-online.com/...able-third-brake-light-flasher-pic12f629.html
While the project has been interesting and I have learned a ton working through it, I feel I may have misunderstood the basic concept. It was my understanding that the pic would work without any programming having to be done to it other than setting it with the two switches. Was this an incorrect assumption?
Where I am having my specific problem is that I get no output from GP0. My guess is that I am not able to set GP0 as an output, but I don't understand why.
I have 5 volts at position + and at GP3, 10.8V at GP4 and nothing at GP5.
