Hi,
Does Atmel application note AVR320 help any (I didn't actually read it, just went and found it)?

Hi again,
Also check out project #0165 in the User Projects section of the Academy tab.

Thanks for the replies Steve.
I have already read AVR320, I would have mentioned this in my first post, but I forgot - sorry.
Project #165 looks usefull though, I would try to have a look at this project.

Hello anders/all,
I’ve the same question:

Thanks.
Here's an SPI interface bit-bashed to a 24 bit LTC2440 ADC taking data to output via RS232.
Here's another - it gets a frequency from an RS232 connection and bit bashes instuctions to an AD9833 DDS.
