OK thanks Angus. I have always found Avrdude unwieldy and have not needed to use it. Likely won't go down that path now either. I have found that Atmels studio 6/now 6.1, is good for checking and programming fuses, even uploads if you feel the need, using avrispmkii programmer. Using the avrispmkii,...

I can only see an Avrdude version of 5.10. I can now see the 328p

I haven't used Avrdude in cmd line to upload or even check a controller.

Is there a tutorial on using Avrdude - the cmd line options are no help!

Thanks again Angus.

Do you have a link to your version of Avrdude please. Mine does not support the 328 at all.

I have looked all over the web for a send/receive sketch to connect two Arduinos - no joy so far. I have never needed to worry about doing this before starting this project. Even Bill Porters easy transfer is ' not that easy'. He uses a data STRUCT but does not give an example of how to format the v...

Thanks Angus - the Avrdude cmd line did not work - it gave a verbose number of chip options. However I did burn bootloader and ran a few sketches which showed the processor timing is back to normal. Can you tell me where I might have made an error in that cmd line script? I have also used Studio6 to...

I have two V1.0 Elevens - one works fine, the other has a problem with running very slowly, about 1/10 normal speed. The 328P was swapped for a brand new chip, today. It accepts sketches and programming using a AVRISPMKii. A test sketch from Examples, Liquidcrystal , needed delay set from 1000 to 10...

Is it possible to powerup the ethermega/Eleven via 12V at Vin/Gnd and still output data via the USB to serial monitor - it doesn't look like it as there is no serial port seen when using external power. I would like to send data out to the PC via serial but powerup usingVin/Gnd. I don't want to use ...

Yes,sometimes its not worth chasing things when its very likely tied up somewhere in the IDE source code. No issues with precision - I have just been head down into it. But appreciate all the efforts put in by you with this rather frustrating issue. Well its a proto only so I am not concerned. Just ...

I pulled out my ethermega and ran the data again - same type of lcd. By the way have a look at this http://arduino.cc/en/Reference/Float In Arduino, float is the same precision as double - it doesn't matter how they are used - still 4 bytes. Serial output V,I,KW,KVA,PF all set as serial.print(X) in ...
