falingtrea 1:ac9595d0f0e7 21 *
falingtrea 1:ac9595d0f0e7 22 * 1.01 TAB 7/6/15 Removed NULL pointer from evbAmbientLight creation call.
falingtrea 2:75adc72aa6a0 23 *
falingtrea 3:68e974f5f532 24 * 1.02 TAB 7/8/15 Send logo to LCD before attempting connection to LoRa network. Added
falingtrea 2:75adc72aa6a0 25 * information on setting up for public LoRa network. Moved SW setup to
falingtrea 2:75adc72aa6a0 26 * beginning of main. Removed printf call from ISR functions. Added
falingtrea 2:75adc72aa6a0 27 * additional checks for exit_program.
falingtrea 3:68e974f5f532 28 *
falingtrea 3:68e974f5f532 29 * 1.03 TAB 7/15/15 Added threads for push button switch debounce.
falingtrea 3:68e974f5f532 30 *
falingtrea 4:49d19abdfd04 31 * 1.04 TAB 10/22/15 Fixed format error in temperature print to LCD. Corrected error in
falingtrea 4:49d19abdfd04 32 * public netework setup. Swapped \n and \r in prinf calls because
falingtrea 4:49d19abdfd04 33 * Windows seems to be picky about the order
falingtrea 4:49d19abdfd04 34 *
