This project implements a simple Morse code flasher on an Arduino UNO. It uses the onboard LED to flash a standard amateur radio "Hello CQ" CW sequence with my call sign, WD8NAQ.
To set up for building and programming the board, use MacPorts or Homebrew to install the following:
- avr-gcc
- avr-libc
- avrdude
The project makefile assumes that the Arduino UNO connects as /dev/tty.usbmodem14201
on macOS. You can define a TTY environment variable specifying a different serial device
connection.
The project in the testing subdirectory allows for the testing of the morse module.
