thomasmorris 12:536eca338ae8 7 Last Revision: Added Mail Box to serial
thomasmorris 8:0e4481b64353 8 Todo:
thomasmorris 12:536eca338ae8 9 make a mailbox within SD card, LCD, network so they can be used from within
thomasmorris 12:536eca338ae8 10 Fix the network so it uses the mail box data.
thomasmorris 12:536eca338ae8 11 Place the LCD write functions in their own function
