Hello to all. I am VERY new to the pic enviornment! Pretty much a novice in the electronics in general. But i think I can learn this :). I am trying to gather Ideas and data for building a digital tachometer for my car. I plan on using the 16c84 for economical and technical reasons (I can electronicly fix my mistakes! no uv needed). If any one has any guidance on electronic design of the Tach I would much appreciate any input. I was thinking I would probably use either the pos coil wire as the signal(reduced of course) or an inducted sparkplug wire via halleffect pickup. I would like to get resolution of about 50 -100rpm which I would like to output to a four character led display(7 seg). I plan on using some sort of c/compiler for the programming because I am not very familiar with assembly code. Any good beginners links would be appreciated. Thanks in advance, Allen
