Re: QRSS ARDUINO shield questions

Hi Colin
As Alan said, there's a book see??for the details. People can still build and operate the QRSS Arduino shield without the book. But the book does contain a lot of other interesting things and would probably be useful for people who want to learn more. There's a huge amount of information on Arduino around the internet too.

Hans has contributed three chapters, including one on QRSS and one on the multimode transmitter shield, to the new ARRL book 'Hamradio for Arduino and Picaxe'. It's well worth a look, it would probably answer your questions.
If I've read it correctly, switches 1 and 2 give a value from 0 to 3 to select modes None/QRSS/FSKCW/DFCW, similarly switches 3 and 4 give speeds of 12WPM/QRSS3/QRSS6/QRSS10.
Loading Arduino sketches into ATtiny chips is covered here:
I think you will need an ATtiny44 or ATtiny84. The 8-pin ATtiny45/85 types don't have enough pins for this application.
Hope this helps.
