Function Documentation

loop()

void loop

(

)

Implicit loop.

This function is called inside a hidden loop in the Arduino framework. We're using it for protothread scheduling. All the real work happens inside the protothreads.

Definition at line 47 of file sapflow_protothread.ino.

            {
  measure();  //< Actually performs measurement. Gated by the sample_timer.
  schedule(); //< Controls the sequence of actions in our measurement cycle
  sample_timer(); //< Sets the sample rate at 1Hz
}

setup()

void setup

(

)

One-time initialization.

This function is called when the microcontroller first starts up or is reset. It's good for things that should only happen once. You do not need to call it yourself. It initializes some hardware, puts the protothreads in a known state, and begins the measurement cycle (which starts with sleep)
