D8 will show the raw input to the ATMega and D5 will show the processed signal which is the one that will be decoded. If you want to see how your noise filter is working you can hook one oscilloscope probe to D5 and another to D8. Send -.- to change the pitch of the tone. Hook up your LCD panel to the Arduino using these pins: LCD pin 1 to GND LCD pin 2 to +5V LCD pin 4 to A5 LCD pin 6 to A4 LCD pin 11 to A3 LCD pin 12 to A2 LCD pin 13 to A1 LCD pin 14 to A0 LCD pin 15 to +5V LCD pin 16 to GND If you hook a speaker between D9 and GND and a telegraph key between D8 and ground you can hear yourself practice Morse Code. If you don't have a 20x4 (they're really only a few bucks more) you might want to leave out the word wrap and scrolling. Sometimes long words or missed spaces will result in only two words left on your display. Frankly, I don't think scrolling makes sense with only two lines. If you are planning on using a 16x2 you will want to make some changes. This version makes use of the 4 digit parallel method of driving the display. When the bottom line is filled, all lines will scroll up one row and new text will continue to appear at the bottom. If a word extends beyond the 20 column line, it will drop down to the next line. The sketch includes funtions for word wrap and scrolling. This project is built around the 20x4 LCD display.
The more dahs you send at the beginning the sooner it locks into solid copy.
WB7FHC MORSE DECODER SOFTWARE
The software tracks the speed of the sender's dahs to make its adjustments. If you are not seeing solid copy, press the restart button on your Arduino. The first few characters may come out wrong while it homes in on the speed. 2.0 (c) 2015, Budd Churchward - WB7FHC This is an Open Source Project Search YouTube for 'WB7FHC' to see several videos of this project as it was developed.
