libpifacedigital v0.3.0

Change Log

v0.3.0

• Changed the function signature of pifacedigital_wait_for_input().
  There was a bug with the old function in that it would return 0 on
  both a possible valid interrupt state and a timeout. It was impossible
  to determine which caused the blocking function to return. To remedy
  this the function now returns a status code and the interrupted input
  state is stored at the data pointer provided. This will break existing
  code using this library and programs using this function will need to
  be updated. It is trivial to update the function call:

  uint8_t data = pifacedigital_wait_for_input(10, 0);
  

  turns to:

  uint8_t data;
  int status = pifacedigital_wait_for_input(&data, 10, 0);
  

libpifacedigital v0.2.0

Now with interrupts!
