Program that implements a digital clock, C/C++ Programming

Write C code for a program that implements a digital clock (HH:MM:SS).

The clock includes a two-digit hour indicator HH (00-23), a two-digit minute indicator MM (00-59), and a two-digit second indictor SS (00-59).

The main interface is through the serial port to the terminal program.

At start or upon reset, the program displays "00:00:00".

The program should use one or multiple timers of the microcontroller to create a timebase of 1 sec that acts as the clock's heartbeat.

In passing of each 1 second, the following tasks should be performed:

(i) SS+1; SS=60?→SS=00, MM+1; MM=60?→MM=00, HH+1; HH=24??HH=00.

(ii) Display the new HH:MM:SS on the terminal program.

Whenever a pushbutton is pressed, the clock should be reset restarting from "00:00:00".

An interrupt routine should be used to detect the pressing of the pushbutton. Thus, select one of the eight pushbuttons that is able to interrupt the microcontroller.

The following can be used as guide to write the code. (do not write code for separately  the following.  The code should compile in ATMEL Studio 6 and able to display in a Terminal Program Interface.

1. Write the code to display time on the terminal program.

2. Write the code to use one or multiple timers of the microcontroller to create a timebase of 1 sec that acts as the clock's heartbeat.

3. Write the code to calculate and keep track of time.

4. Write the code to detect the pressing of the pushbutton using an interrupt based approach, and reset the clock.

5. Write the code to implement additional functionalities to the C program (considered for Problem 3 only).

6. It would be helpful to understand your coding if you draw a flowchart and develop the corresponding pseudo.

7. Processor, 8 bit,  ATMEGA 128, 16MHz.
