Microcontroller Programming » Motorcycle tachometer
June 09, 2014 by scootergarrett |
Motorcycle tachometer So I got the idea that I could make a digital tachometer for my motorcycle (1980 kawasaki 750), for various reasons (the current mechanical one leaks oil on my pants, feedback to the choke so it tracks a set rpm when it warms up instead of revving up to 3000rpm when I'm getting ready and pissing off my neighbors). Anyways with some help from someone who has taken the signal from the ignition points and conditioned it to a usable signal. I now have a prototype circuit Circuit diagram which I don't clam to fully understand yet, I mean a nand schmitt trigger who comes up with this stuff. and the code that counts 3 spark cycles then dose math and prints the calculated RPM to the LCD
The code needs is still in prototype mode. I thought I would share where I'm now. I need to get a good case which is a ways off |
