mwthewsey 11:b538e73841ae 11 *The ENVDISPLAY class enhances the abilities of the TextLCD class to be
mwthewsey 11:b538e73841ae 12 *relevant for an ENVIRONMENTAL sensor.
mwthewsey 11:b538e73841ae 13 *Temperature, pressure, LDR and time readings are passed into the object using
mwthewsey 11:b538e73841ae 14 *the UpdateData function. A custom message can also be displayed using
mwthewsey 11:b538e73841ae 15 *SendMessage, with the option of returning to enviromental data.
mwthewsey 11:b538e73841ae 16 *
mwthewsey 11:b538e73841ae 17 *Two buttons are required for time setting functions. Pressing button 1 enters
mwthewsey 11:b538e73841ae 18 *the lcd into a set_time state.
mwthewsey 11:b538e73841ae 19 *
mwthewsey 11:b538e73841ae 20 *Device initialised with: ENVDISPLAY lcd(D9, D8, D7, D6, D4, D2,PE_12, PE_14);
mwthewsey 11:b538e73841ae 21 *lcd.Start() must be run to begin operation.
