Hi. Thank you for your contribution with this library. I'm new to coding, so may be wrong with this. I've built my code around your example code, reading pressure data from multiple RSC pressure sensors. I'm reading out correct serial numbers, temperatures, etc. from the sensors, but the pressure values don't seem to be correct. Some appear offset quite a lot, and others aren't changing at all. I was curious whether the error is in my code or (respectfully) in your library.

I found a technical paper from Honeywell, where I couldn't identify this process in your cpp file (link below):
https://sensing.honeywell.com/auto-zero-calibration-technique-pressure-sensors-technical-note.pdf

In my code, I'm only additionally setting the data rate, compared to your example code and creating multiple instances of the class for my multiple sensors. If I should be doing something in my code to auto-zero, I'd appreciate any advice.

Many thanks.

Hi, Nice library, but it just doesn't compile. There is no valid conversion for the catalog_listing member function etc.

Honeywell_RSC.h:49:41: error: invalid conversion from 'const unsigned char*' to 'char*' [-fpermissive]
char* catalog_listing() const {return _catalog_listing;}
