I am using an SDI-12 library which you can find at Github here here. It works great on the UNO or any other board but gets errors when I try to compile with Teensy. The error and codes are posted below. Any thoughts on why Teensy would give an error that variables are not declared but if I compile for UNO all of the variables are declared?
Here is the code I am using which works perfectly on an UNO.
