8. Morse Code Module Morse Code Data Structure Morse Entry Morse Code Reading Morse Code Table

9. Morse Code Data Structure typedef enum DitDah {DIT, DAH, EMPTY} DitDah; #define MAXSIZE 7 typedef struct MorseCode { DitDah elements[MAXSIZE]; int size; } Morse; Morse Code Structure has it’s own enumerated type which can be DIT, DAH, or EMPTY Size keeps track of the number of elements in the Current Morse Structure Other functions support this structure and modify it

10. Morse Structure Function Morse clear_morse(Morse key); Morse add_morse_dit(Morse key); Morse add_morse_dah(Morse key); Morse fill_rest_empty(Morse key); clear_morse initializes the structure array so all EMPTY, this is normally called when a new Morse sequence is started add_morse_dit adds a DIT to the array and increments size add_morse_dah adds a DAH to the array and increments size fill_rest_empty is called on when input of current Morse sequence is stopped and fills the rest of the array to empty

11. Morse Code Reading int compare_morse(Morse key); void init_key_output_table(USBOutput KeyTable[MAXKEY]); USBOutput find_usb_output(int keynumber,USBOutput KeyTable[MAXKEY]); Init_key_output_table initializes the USB output table array Not sure what output are so far, the table is Integers for now compare_morse iterates through the Morse Code Table array and returns a number that corresponds to it find_usb_output returns the output needed from Table

12. Morse Code Table const static DitDah MorseTable[MAXKEY][MAXSIZE] = { {DIT,DAH,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY},/* A */ {DAH,DIT,DIT,DIT,EMPTY,EMPTY,EMPTY},/* B */ {DAH,DIT,DAH,DIT,EMPTY,EMPTY,EMPTY},/* C */ {DAH,DIT,DIT,EMPTY,EMPTY,EMPTY,EMPTY},/* D */ {DIT,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY},/* E */ {DIT,DIT,DAH,DIT,EMPTY,EMPTY,EMPTY},/* F */ {DAH,DAH,DIT,EMPTY,EMPTY,EMPTY,EMPTY},/* G */ {DIT,DIT,DIT,DIT,EMPTY,EMPTY,EMPTY},/* H */ {DIT,DIT,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY},/* I */ {DIT,DAH,DAH,DAH,EMPTY,EMPTY,EMPTY},/* J */ {DAH,DIT,DAH,EMPTY,EMPTY,EMPTY,EMPTY},/* K */ {DIT,DAH,DIT,DIT,EMPTY,EMPTY,EMPTY},/* L */ {DAH,DAH,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY},/* M */ {DAH,DIT,EMPTY,EMPTY,EMPTY,EMPTY,EMPTY},/* N */
