The coolSAA1064 arduino library handles the 7 segment Philips / NXP SAA1064 driver for easily displaying and scrolling numbers and words on up to four displays.
Hi,
Arduino Leonardo hangs when using this library if SAA1064 object is created as global object. Reason is that Wire.begin() is called before Arduino setup() is called.
Fix: add SAA1064.begin() method and move Wire.begin() to this function. Call SAA1064.begin() in Arduino's setup() function. Then it works fine.
