Question

use commands move and mvprintw in c language to code this binary clock that sleeps for one second and changes display. time in the format 'h:m:s:" will be provided by user input. i have a clock.sh that displays the time in "h:m:s" format every second. This is the code in clock.sh.

while true; do

current_time=$(date +"%T") # Get the current time in HH:MM:SS format

echo "$current_time"

sleep 1

done

Now, i need a display that looks like the below picture

all this code will be put in a GitLab file named display-nopi.c. Here is my current code for this file.

#include <ncurses.h>
#include "display-nopi.h"

static int is_display_open = 0;

int open_display(void) {
if (!is_display_open) {
initscr();
start_color();
init_pair(1, COLOR_RED, COLOR_BLACK);
init_pair(2, COLOR_GREEN, COLOR_BLACK);
init_pair(3, COLOR_BLUE, COLOR_BLACK);
is_display_open = 1;
return 1;
}
return 0;
}

void display_time(int hours, int minutes, int seconds) {
if (is_display_open) {
clear();
display_hours(hours);
display_colons();
display_minutes(minutes);
display_colons();
display_seconds(seconds);
refresh();
}
}

void display_colons(void) {
attron(COLOR_PAIR(1));
mvaddch(3, 16, ':');
mvaddch(3, 20, ':');
attroff(COLOR_PAIR(1));
}

void display_hours(int hours) {
mvprintw(3, 14, "%02d", hours);
}

void display_minutes(int minutes) {
attron(COLOR_PAIR(2));
mvprintw(3, 17, "%02d", minutes);
attroff(COLOR_PAIR(2));
}

void display_seconds(int seconds) {
attron(COLOR_PAIR(3));
mvprintw(3, 21, "%02d", seconds);
attroff(COLOR_PAIR(3));
}

void close_display(void) {
if (is_display_open) {
endwin();
is_display_open = 0;
}
}

The display will look something like this (displaying 21:10:37, using a 24-hour clock to display 21H, 10M, 37S):

**Diagram Explanation:**

- The diagram uses H, M, and S to represent hours, minutes, and seconds.
- The top two rows are unused.
- The display uses 32s binary digits, indicated by groups of four lit white LEDs.
- The bottom part shows ones binary digits.

The hours, minutes, and seconds must be displayed in three distinct colors and can be oriented in any direction. If the ones digit is on the bottom, the seconds must be on the right. If the ones digit is at the top, the seconds must be on the left. Here is a video showing the clock in operation on a Raspberry Pi: [clock.mov](#).

The main "clock" program compiled from C is designed to read times from `stdin` and display them as above. To make a complete clock, a shell script called `clock.sh` must print the times to be displayed by the clock executable. The complete project is broken into these two pieces so that each can be independently tested.

Expert Solution

Step 1: Introduction

To create a binary clock in C using the ncurses library, you can modify your existing code in display-nopi.c to read the time from the output of your clock.sh script and display it in a binary format. To do this, you can use system calls to execute clock.sh and read its output.
