QRSS ARDUINO shield questions
|
"dd5cf_colin"
Hi Hans and all,
I have a couple of questions about the arduino shield. 1: If I run the UNO battery power can I connect it to GND and Vin (as recommend by the arduino website) through your QRSS shield? 2: I have looked through the sketch to find out which DIP switch does what but due to my limited knowledge I cant make head or tail of it, can you tell me the various switch positions / modes? at the moment I have only switch 1 in the on position this seems to be QRSS 3. 3: I think it must be possible to upload the sketch to a ATtiny chip or similar (sorry lack of knowledge again) and breadboard the QRSS shield with the chip, what sort of chip would I need ? 73 Colin DD5CF / G1ZOS |

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.

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.

Thank you both for the information and the links Alan. Have you any advice for me about question 1 of my last post: If I run the ARDUINO UNO on battery power can I connect it to GND and Vin (as recommend by the arduino website) through your QRSS shield? My contribution to the "BS170's in new kit PCB's - opinions please?" post is why not supply a couple of 2N7000's in a seperate bag and those OM's who are not confident about which way round the BS 170's go can have the choice. 73 Colin DD5CF / G1ZOS --- In QRPLabs@..., Hans Summers <hans.summers@...> wrote:

Hi Colin?
All of the standard Arduino pins are fed through the shield in the standard way. So if the website recommends that the Arduino can be powered by Gnd and Vin through a shield, this would apply to the QRSS shield too. But to be sure: can you provide a link to the part of the website that you are referring to?

Hi Colin Yes, I see. Yes, you can provide a battery voltage > 7V, through the Vin pin, on my QRSS Arduino shield. The QRSS shield provides access to all the usual Arduino connectors on the two 6-pin and two 8-pin headers - which includes Gnd and the Vin pin.?
