Comment on My couch programmer by Marcus

Sorry, I do not know it exactly.
But the programmer is extremely fault tolerant. So you can simply check it both ways. One shold work. After that you can mark it.
I often confuse my connections accidentally – despite of not programming the chip – nothing bad happened until today.

Comment on Developing Software for the Atmel AVR with AVR-Eclipse, AVR-GCC & AVRDude by Marcus

If it is not on the AVRDude list then it is simply not supported by avrdude. Perhaps you can try WinAVR to see if you have more luck.
Sorry for this answer.

Great stuff!

When I get to picking hardware from avrdude list (“Click on Add to configure your avrdude and programmer.”), mine is not in the list. I’m using STK525 ( http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3878 ). I currently have to use FLIP software to program it, which isn’t bad, but requires a makefile, etc. I poked around the AVRDude project website, but couldn’t find anything regarding the 525 or flip.

I hope it helps. Just report any irregularities as an issue

Comment on Arduino & AD7746 by Marcus

I just had a look at the Freescale MPR121 – looks good. Perhaps that chip has enough channels for you
The basic measurements and interpretation as propose din this post also applies to that chip.

I thought so. *sigh*
Thanks for your answer, i’ll keep searching!
Cheers!

Unfortunately not.
Yes, I2C is a bus and there can be many I2C devices on a bus. But two devices must not share the same address. As far as I have seen it the AD7746 does not offer the possibility to change the I2C address of the device. Therefor you can only have one AD7746 on one bus. There are other devices with similar function, which have mor inputs. Check the Analog Website or Atmel – other vendors have capacitive Input devices as well.
