EMBEDDE OS, LINUX UBUNTU, BEAGLEBONE BLACK

Develop a user space program that will flash the BeagleBoneled to represent a word provided to the program in Morse Code.

> MCode -w Welcome would flash the led to indicate Welcome in Morse Code

Find the file McodeMod.c to build your BBB application you must use at least two files main.c and McodeMod.c to create Mcode.

File McodeMod.c :

#define CQ_DEFAULT 0

/* the empty string, follwed by 26 letter codes, followed by the 10 numeral codes, followed by the comma,

period, and question mark. */

char *morse_code[40] = {"",

".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",

".-..","--","-.","---",".--.","--.-",".-.","...","-","..-","...-",

".--","-..-","-.--","--..","-----",".----","..---","...--","....-",

".....","-....","--...","---..","----.","--..--","-.-.-.","..--.."};

inline char * mcodestring(int asciicode)

{

char *mc; // this is the mapping from the ASCII code into the mcodearray of strings.

if (asciicode > 122) // Past 'z'

mc = morse_code[CQ_DEFAULT];

else if (asciicode > 96) // Upper Case

mc = morse_code[asciicode - 96];

else if (asciicode > 90) // uncoded punctuation

mc = morse_code[CQ_DEFAULT];

else if (asciicode > 64) // Lower Case

mc = morse_code[asciicode - 64];

else if (asciicode == 63) // Question Mark

mc = morse_code[39]; // 36 + 3

else if (asciicode > 57) // uncoded punctuation

mc = morse_code[CQ_DEFAULT];

else if (asciicode > 47) // Numeral

mc = morse_code[asciicode - 21]; // 27 + (asciicode - 48)

else if (asciicode == 46) // Period

mc = morse_code[38]; // 36 + 2

else if (asciicode == 44) // Comma

mc = morse_code[37]; // 36 + 1

else

mc = morse_code[CQ_DEFAULT];

return mc;

}

Convert the Morse Code program into a BBB Device Driver and write a user program to use the driver. The Driver must support multi-user access to its resources.

Please submit the source code for the driver and user application, make file and evidence that it worked.
