I have asked for some help on this list recently. I am trying to learn enough of both the hardware and software needed to accomplish my first project. I am a mechanic by trade and have very little programming experience. I can however understand schematics and have no problem building what I need as far as the hardware goes. My problem is really two fold. I need a schematic so I can first build this project and then I need the software to drive it. I have MPlab V5.0 but I am not sure where to start. My project is rather simple. I am trying to build a speedometer for our model railroad. HO scale 1:87 ratio. I have two track detectors already and the PIC. I have two "Seven segment" LED's that I want to use for the display. I understand that I will have to multiplex the display to reduce th I/O port requirement. Several members of this list sent me to pages with examples on how to drive a single digit display. There was some text outlineing the multiplexing idea but no code or schematic. I am sure someone out here could whip this up in a few minutes! I have spent several hours just doing research already. If anyone out there could get me through this first project I would be very greatful! After that the mechanic in me can tear this one apart and make changes so I can learn the ropes! I need a door of widom opened here please!
