* TimeSerialDateStrings.pde
|
|
* example code illustrating Time library date strings
|
|
*
|
|
* This sketch adds date string functionality to TimeSerial sketch
|
|
* Also shows how to handle different messages
|
|
*
|
|
* A message starting with a time header sets the time
|
|
* A Processing example sketch to automatically send the messages is inclided in the download
|
|
* On Linux, you can use "date +T%s\n > /dev/ttyACM0" (UTC time zone)
|
|
*
|
|
* A message starting with a format header sets the date format
|
|
|
|
* send: Fs\n for short date format
|
|
* send: Fl\n for long date format
