32 bit math with 16F8XX
PostPosted: Fri Feb 01, 2008 8:09 am     Reply with quote
Hi,

I was wondering if anyone can suggest the best way to do 32 bit math with this series. I don't program a lot so I'm sure what I have in mind isn't the best way to proceed.

I need to download a bunch of correction factors from an EEPROM via SPI, then perform Horner's method on a transducer input. The correction factors are in IEEE-754 32 bit format.

Is there a slick way to reference these 4 consecutive byte chunks so I can perform the calculations or do I have to OR and shift to create the factor first?

TIA
PCM programmer

Post a link to some sample code or an appnote so we can see what's required.
