From the Workbench: Arduino CW Keyer
I’m pleased to announce my Arduino CW keyer code is ready for prime time and available for download here. At first this started out as merely porting my PIC keyer code to the Arduino, but the advanced features and ease (and joy) of coding for this platform encouraged me to venture further. Beyond my original PIC keyer features, this creation also has a speed potentiometer, a serial port command line interface, more and bigger memories, QRSS, HSCW, and memory macros. It also has a callsign receive practice mode, CW keyboard, and Hellscreiber sending capability. I’m trying to figure out a way to interface with Ham Radio Deluxe and N1MM, and I have in the works a frequency counter option for use within homebew rigs, like my original PIC keyer.
The code is stable at this point, and I’m not aware of any bugs. If anyone tries this code out and has bug reports, feedback, or feature requests, please drop me a comment. Next I’m going to finish the Yaesu rotator computer interface.
I have a lot of ideas for an Arduino controlled antenna tuner swimming around in my mind. After having two commercial automatic antenna tuners that were disappointing, I think I can build a better mousetrap. The tuner will be a balanced L design capable of 150 watts or more, but still capable and accurate at QRP power levels.
great stuff — i have been following the arduino for some time but have never bought one — now i need to !!! — would like to figure out a morse decoder with an lcd screen with inputs directly for a qrp rig ( tuna tin swl type rigs) and or some type of freq readout from the smaller rigs !!
keep up the great work
How about contributing to the OpenQRP project by K1EL who is using an Arduino to control the entire QRP rig: http://openqrp.org/ He has ported special CW keyer code from an N6?? and is very excited about the capability.

Help! I can’t compile the code!
Vincenzo, what error are you getting?
There may be an issue copy-and-pasting the code. Let me see if I can drop a text file somewhere for you to download.
Vincenzo, try copy and pasting the text from this file into the Arduino Sketchbook:
Many thanks for the new text file… but now compiler say this:
In function ‘void setup()’:
error: ‘A2’ was not declared in this scope In function ‘byte pot_value_wpm()’:
In function ‘void ptt_key()’:

Again many thanks for your help.
