I need to know if anyone has built or knows how to build an odometer (with memory) for a car using a 6 digit LED common anode display based on a PIC. I've looked for some examples and I don't have a very good understanding of ASM code to program a PIC or even a modify a similar circuit to do what I want. I've looked through Nigel's tutorials but there must be something basic about programming I just don't know. I have a 16F628 and a few circuits based on the chip I was hoping to be able to modify but I'll be honest...I don't have clue!
I'm building a digital dash for one of my old cars and already have designed fuel, battery, oil pressure, and water temperature around lm3914's and ICL7107's. I can get a signal from the Vehicle speed sensor which outputs 8,000 pulses per mile. I could build it using older CMOS or TTL circuitry but that would be an overly large circuit.
I want to stress I don't mean to ask anyone do to it for me, just for help or guidance as I'm not getting the gist of it.
Thanks everyone!
