let's think ...

IF you calculate the linearisation OUTSIDE the Pic, and trunk it to the PRECISION claimed ( not the resolution, eh ...)

I'm sure a lookup table, or a couple of " ax+b " regressions could be used.

But that implies ... the sensor and the PIC are married for life !!!

I did think of that early on. I think you need to map all possible pressure readings (at your needed precision) across your range, but then also map for every possible temperature change across all pressure readings in that range. I think it very quickly becomes an impressive size lookup table yes ?
I suspect my shorts are safe, but if the poster above can do it I'll listen :-)
