Lockup on SAMD Based Arduino MKR 1500 about arduino-sdi-12 HOT 4 CLOSED

Turns out it's something up with passing the object in that example.

If you change the example to pass the object as a pointer (and use the different begin function):

 SDI12 mySDI12;


  pinMode(sensorPins[pin], INPUT);
  mySDI12.begin(sensorPins[pin]);
  Serial.print("Checking pin ");
  Serial.print(sensorPins[pin]);
  Serial.println("...");
  scanAddressSpace(&mySDI12);
  mySDI12.end();

And also change the supporting functions to pass in as pointer (e.g. void printInfo(SDI12 * sdi, char i){) as well as how you reference the sdi object (from . to ->) it works just fine and dandy.

There must be something up possibly with the newer versions of the compiler.

So, is this something to fix or not?

I reopened this issue with something that was slightly related. But it turned out after getting the original issue with the pointers sorted, plugging the Arduino into a daughterboard with level converters caused this related issue. It was outputting a 48MHz signal which I thought might have been related to the clock gen/TC, but it turns out it was the level converter (TXB0108) causing problems.

As for what caused this original issue. Is it reproducible on other SAMD boards with the examples and the latest SAMD libraries/compilers?

I haven't had any problems recently with my Feather M0.

Level converters are often a hassle.
