PIC Microcontoller Math Method

Floating point conversion routine

by David Lions

I made a utility to convert a floating point number into byte representation. It can convert into several formats, Hitech 24 Bit, IEEE 754 32Bit, and Microchip 24 and 32 bit format used in their application note AN575. It also converts back the other way, and shows information about the format being used.

We are doing a lot of manual calibration. This involves calculating gains and offsets on paper, then having to program them in byte-by-byte. The purpose of this was to get the byte representation quickly and easily. We only use Hitech 24 bit but I thought I'd add some other formats as a learning excersise, make it more useful to others, and justify 1Gb of disk space used by Visual C++.

Hey, that's neat. I have a similar program available you can download for free at the link included.

This is the same program we provide with the PAK-I, PAK-II, and PAK-IX math coprocessors.
