A wake up light using a table lamp and a Stellaris Launchpad. The project is described here: http://beagaroo.wordpress.com

The project can be compiled in eclipse CDT with the GNU ARM plugin (http://sourceforge.net/projects/gnuarmeclipse/) installed along with the GCC ARM Embedded compiler toolchain (https://launchpad.net/gcc-arm-embedded) .

• lights: Controls an AC dimmer circuit to set the brightness of a lamp attached to it.
• sound: Uses PWM to play back a sound stored in a header file.
• time: Used to get and set time form the RTC of the microcontroller and set alarms.
• uartBt: Uart connection to the HC-05 module. The incoming commands are expected to end with a newline and carriage return "\n\r".
• buttons: Functions to poll the snooze / alarm-off button.
• lcd44780_LP: Controls an LCD over GPIO. Not used in the project at the end.
• syscalls: Lowest layer to newlib for printf and malloc etc.
• LM4F.ld and LM4F_startup.c: Linker script to tell the GCC linker what goes where and startup code that runs before main.
• main.c Implements all the commands and the application level logic.

• Dimmer(lights) Pins: PE1(0 crossing input), PE2(dimmer control output)
• UART(2) Pins: PD6-7 (PD6=U2Rx, PD7=U2Tx) - used for UART to Bluetooth converter (don't forget to cross UART pins)
• PB2 is used as output for sound using T3CCP0 for PWM.
• PC6 is used as output for sound amplifier power-enable / shutdown.
• PC7 is used as input for the snooze button.

These pins were previously used for a UI system based on buttons and an LCD but are not used anymore.

• LCD Pins: PB0,1,4-7
• Buttons: PA2-6

• Get time: Send 't'; Light will respond in its time format.
• Set time: Send 'T' followed by the time format. e.g. T1:16:45:10 will set time to Monday, 16:45 and 10 seconds.
• Get alarms: Send 'a'; Light will respond with 7 alarms in time format. Alarms that are not set will be sent as 7:00:00:00.
• Set alarms: Send 'A' followed by up-to 7 comma separated time values.
• Set Maximum alarm Brightness and Delay: B<Maximum Alarm Brightness><Alarm Delay>. Brightness is in percentage (0-100); Alarm delay is the time taken in minutes for the ligth to ramp up to the maximum allowed brightness.
• Set Light Brightness: Send L followed by brightness in percent. e.g. L35 will set the brightness to 35 percent.
• Snooze Alarm: Send 'z' and the alarm sound will stop for 10 minutes but the light will stay on. This command is currently unused.
• Stop Alarm: Send 'U'.
• Demo Mode: Send 'd' and the light will ramp up its brightness gradually to full and gradually lower it back to 0.

Time format <Day of Week>:<Hour>:<Minute>:<Second> where <Hour> is in 24-hour format and <Day of Week> is a number (0-6) where Sunday=0, Monday=1, ..... Saturday=6
