Posted on by Robin Ding Leave a comment Ham Radio

Yack is an open source CW keyer library and application for the ATMEL AVR Architecture. 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.
