I need good idea. In my project i have 2 board (UNO named Slave1, Slave2 )interfacing to NMEA 0183 device (GPS reciver) and master (UNO named MASTER)board with SD CARD, LCD display and serial output to ROBOTEQ controller.
I need to pass data from Slave1 or Slave2 to Master.
I can extract latitude and longitude with TinyGPS++ library, but its impossible to store and transfer over I2C bus double class variables values cause i have lost of precision.
May be somebody have good solution for this trouble?
