This group project, an assignment for subject Embedded System Programming in University of Malaya. The concept is using Ticker and Interrupt to perform specific functions. Ticker is mainly for updates/shows/blinks the display. Interrupt is mainly for changing the cursor location and select function. Using built-in C++ functions (localtime & set_time) for the time function. In additiona, the code also shows certain values on terminal (using putty/teraterm) for debugging.
- Display time (AM/PM)
- Adjust time
- Set alarm. (Indicator if alarm is ON/OFF)
- Initial setup at reset button press.
- Liquid Crystal Display (LCD)
- Mbed application board (JOYSTICK & BUZZER)
- Mbed LPC178
- Solderless Breadboard
- Wires
