Re: Optical Mouse Navigation
I've done some more testing today and noticed that if there are 2 different texture surfaces the mouse changes scale and it isn't the same each time.
today I put a stripped down mouse assemble on a 3/4" drive shaft. Took some work to get the distance right. Wow, instant encoder and the accuracy and repeatability look good. The real nice thing is no interrupts. I also noticed that there is a software SPI library included with pic c. If the terrain following doesn't work out then use it as a 400dpi encoder.
