Remove float calculations in main.c/gettemp() #21

Closed jjmz closed 7 years ago

jjmz commented 7 years ago

Hi, it's been a lot time I have not monitored the project.

Using float is generating more than 1K of code! This version of gettemp only uses 80 bytes to return Celcius or Farenheit depending on CONF_C_F.

Some approximations are needed, I created an .ods file to check if approximation gives a valid result.
