![]() There’s even a bit of silly stuff thrown in there for fun. There have been ten revisions so far, each one adding more capability to the device, I hope the code can be improved further still. And i added a TO DO list, for example TODO: add press any key to abort change pitch of morse key sound add numbers and special characters maybe reduce system to one key, short press advances menu, long press to use provide ability to enter a custom message ie callsign direct from the keypad beacon menu support serial control or ethernet if possible special sounds? psk replies? A todo list was something that i later found to be an invaluable way of adding things that needed to be fixed. This project exists of a Semi-automatic CW Decoder, Called Morseduino. I added a notes section that described the programs way of working. Nice to use for CW practice, but also as a tool for if the straight key is not. ![]() For example // here is where the setup will be // here is where we will define all the variables // This is the routine that converts a letter into dits and dahs // this is where the menu code will live And so on. I learned somewhere along the way that good practice was to write out all your comments first, then fill the code in later. I browsed around the web trying to improve my programming skills, as this was probably the hardest code I had written to date. Much smarter,simpler and good enough for what i was trying to do here, keep it simple for me and if anyone else wanted to use it. One variable, the program number, incremented or decremented by the left and right keys. One example i saw, had left or right scrolling through all of the functions, looping back around to the start. GND Pin 38 - Negative leg of both the LEDs via 2k resistor 2. Once you’ve tried it your way, head over to the web and see how the programmers do it! I decided to look around the web. Breadboard Add Tip Ask Question Comment Download Step 2: Step 2: Start Your Wiring Take your Breadboard and start wiring. I believe in trying to do it your self, so you can learn first. ![]() I did manage to get it working but wondered if there was a smarter way to go about it. I would then also need to keep a number at the intersection of the row and column which would be the page number.

This meant holding a variable for the column number, a variable for row number, both of which to be looped around or limited. A common practice is to employ frequency shift keying (FSK) for QRSS. Each row would represent a type of function and the pages along the row each related to each other. MFJ Enterprises Original MFJ-557 Deluxe Morse Code Practice Oscillator Straight Key w/Volume Mini CW Key Automatic Morse - PUTIKEEG Morse Code Keyer Shortwave. This is much more narrow than even the sharpest filter you’d use for regular Morse code operation. Initially i imagined a grid system of menus using up/down/left/right. The code was a little complicated to write, but it was my first attempt at a menu system.
