Hello all,

I'm wanting to continue advancing my PIC programming knowledge by taking my recent train controller project to another level. If you have read my postings, and/or assisted me, on my recent project, then you know that I'm a novice in the true meaning.

I've done quite a bit of reading the past couple days but just haven't found the right starting code for what I'm wanting to do. Maybe one of you can point me to some code that will help jump-start my project.

I'm wanting to control the speed and direction of the small dc motor in a HO gauge train. The current requirement is less than 1 amp. The max voltage would be ~12 VDC. I would like to use a pot to control the speed and I would use my existing reed switches to control the direction, via the PIC input pins.

In addition to some pointers to code samples, do you think that I can use a 12F683 or should I go to the 16F684. Of course, any other PIC that is you feel more suitable. What H-bridge IC would you recommend and do you know of any schematic diagrams that you could point me to that might show a PIC interfacing to the h-bridge?

Thanks,
Mitch
