A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!).
Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs.
You can personalize the transmitted message and the morse speed (in WPM).
In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz.
Enjoy this example and if you will appreciate it, please sens me a feedback!
...It has been natively designed for an ATTINY45 Chip but can be adapted to other chips too. This is a hardware / HAM Radio application.
How to install: Download the binary package, flash main.hex file into Flash memory and main.eep into EEPROM using AVRdude.
For more details and documentation please retrieve the latest complete source code from the SVN repository.
Suggestions, feature requests and questions are appreciated!
This project is aimed primarily at users of the Icom R20 Communications Receiver and it's predecessors (R3, R5, R10). The intent is to provide ability to extend the capabilities of the radio, and provide an API to programmers interested in it.
