I tested the SDI12_Mod.h solely and the microcontroller will restart after begin the library 🙁
Problem solved(7 Feb 2017)
I am now using hardware interrupts D10 (you need to cut the trace solder a jumper to D10 at SJ1 on the back of the board)
Now you don’t need the pin change interrupt library(conflict with SDI library)
Below is the code:
