Hi!

I need a source or reference where you have the formula of double idDHTLib::getDewPointSlow() from. According to the link in the comments the only function I consider to be relevant is FUNCTION DWPT(T,RH) but it looks way different to your approach. And the website of NOAA is like an information grave.I would be happy for any hint!

Hello.

I just wanted to tell you that when I include the library in a sketch by navigating the IDE menu through Sketch>Include Library>idDHTLib, this is what gets written into the sketch:
#include <idDHTLib.h>
#include <idDHTLib_cb.h>
#include <max_interrupt.h>

which causes many many errors during compiling, I don't know how Arduino decides which .h files should be included with a library but the files #include idDHTLib_cb.h & max_interrupt.h should obviously not be included in the sketch. For completeness I'll include the error message generated when these files are included, this is the complete error message(sorry about the poor formatting, I have no clue about how I could post this in a nice way, if anyone knows please feel free to inform me), this is the end of this post, the rest is the error message:

Arduino due has no sei(), cli(). plz change it to

noInterrupts(); delta = micros() - us; interrupts();

The code in the acquiring function ignores two of the 5 bytes returned by a DHT11 on the assumption neither temperature nor humidity results will have a decimal component. This is not correct for the DHT11 part I have (for Temperature anyway) and also contradicts the spec to be found here http://www.micropik.com/PDF/dht11.pdf. Maybe later models are better implementing the spec? Either way ignoring the decimal component in the Temp field creates an incorrect checksum error.

Not an error, but the sum field in the acquiring function is declared as an unsigned 8 bit field so the instruction to mask it using & 0xFF has no effect. Effectively this is just wasting processing cycles.
