Conquer the Divide - Faster Integer Division

Conquer the Divide - Faster Integer Division

Introduction

How to implement C-style integer division on a microcontroller that doesn't provide appropriate instructions? In school we learn how to divide long nunmbers [1]. Wikipedia tells us that we can do better in certain cases [2]. However, these algorithm are only better for numbers longer than a certain limit. For C operations they don't give any advantage. This article presents an algorithm based on piecewise polynomial approximation to implement this operation.

Botboarduino drivers

Ok guys it's been a while since I've been on I'm glad everything is picking back up.

I recently had to wipe my computer after getting a virus. Which means I lost all my drivers and code and etc. I managed to get arduino up and running but my botboarduino needs drivers to work. I'm kinda freaked out about catching another virus and I can't seem to find the correct drivers for ft232 uart. I tried one place but it keeps asking me for a password to open it. And when I point the device manager it refuses to see the zip file.
