Hi,
I just wrote a SPI driver for the AVR processor for a little project I'm doing. The driver is attached.
Also attached are some small changes to the ArduinoMega demo which change the current 1000hz tick to 100hz and make the I2C/SPI options explicit on mcuconf.h (disabled by default).
Best regards,
Fabio Utzig

Re: AVR SPI driver and misc changes
Hi,
Currently there is no maintainer for the AVR (BTW interested?), I'll merge it when I have some extra time.

Hi Giovanni,
Since AVR port is kinda slow, I guess I could maintain it. As long as we're talking GCC based port. This new IAR port of the other thread I'm not sure. The main reason I'm quite afraid of the task is because I really dislike forums as a way of maintaing anything. I'm more of a mailing list kinda guy. You seem to be the only maintainer of any project I follow that really uses a forum...
Anyway, my suggestion would be for you to create a forum for each architecture (AVR/MSP430/etc) supported so the "Development and Feedback" would be more tailored to the Kernel which would make it easier to separate port specific issues from kernel issues.
I need to check how to receive emails for posts. I have subscribed to all forums but only receive emails when I open the website and also the emails don't have the content of the post. Not sure if that is possible...
Regarding some tasks like writing drivers, testhal, docs and such I'm easy with it. Some issues/doubts I have I'll better post on the "call..." thread.
