Subject: Morsel Code
What matters is how you use it.
This module uses a modified Morse code: Dots and gaps between parts of a letter are 1 unit, dashes and gaps between letters are 2 units. Letters might not match their original Morse code representation.
Letters are associated with a code as follows: Start at the letter in the top-right table cell (E) and follow a path. Including the starting point, hollow circles represent adding a dot and filled circles represent extending the last signal from a dot to a dash. The diagonals moving out from the corners connect opposite corners through wraparound.
Identify the letters given by the LED. Look in the table for the word made from these letters. Now move from the top right cell of the 4x4 grid to the cell given by this word by shifting all rows or all columns at once in alternating directions, wrapping around as needed. Multiple moves may be needed. While moving, keep track of the position given by the statuslight's position in a 4x4 overlaid on the (partially unoccupied) module space.
If the first letter of the word was transmitted earlier in the sequence than the second letter, use the right corners of this cell. Otherwise use the left corners. If the third letter of the word was transmitted earlier than the fourth letter, use the bottom corner. Otherwise use the top corner. Take the letter in this corner and submit it using the telegraph key. Units should be kept somewhat in proportion.
