#136056 - A couple of options Responding to: ???'s previous message |
I ran across a math coprocessor chip that looks interesting (I haven't used it myself), it has a serial interface so it doesn't consume a lot of IO pins. Check it out at http://www.micromegacorp.com/
In all of my coding I've yet to need floating point...I just don't want to put up with the code bloat and speed that it involves. Instead I used integer math. When I needed to do some trig functions for calculating compass headings (similar to what you're doing actually) I found that the cordic algorithm produced results accurate enough for my purposes. If you do a quick google search on cordic you'll get a lot of hits... Dennis |
