This is my first project and I have taken an interest in using PIC microcontrollers. I have been doing alot of research and reading of texts and pdfs, currently reading 'Embedded Design with the PIC18F452 by John B. Peatman' which I am following really well.
The first goal in my project is to simply display the speed of the motorbike on an LCD (like on newer models motorbikes), though I am not sure how I should take my readings. Should I take the approach of putting those magnetic sensors on the forks and wheel to measure the rotational speed or would there already be a wire in the instrument panel powering the existing analog speedo that I could read voltage levels from that correspond to different speeds, if so is there an easy way to find it... I have a Honda VTR1000F '98 model and a Kawasaki GPX250R '91 model, so if anyone is familiar with the speedo electrics of these or similar bikes or could inform me of any links on the subject i would be grateful.
I first considered using a PIC16F877 which I first got familiar with reading its datasheets etc as it has a/d converter, and recently i have been reading books on the PIC18F452 (which I will probably use because it has a larger instruction set and i've become familiar with how it works, even though i probably won't make use of half its functionality at the moment.)
I will be coding in assembly language because I want to master the operations of the microcontroller, when I get more proficient I will consider using C or Basic.
I will keep you all posted on my progress.
Any advice, links, or whatever will be much appreciated.
