Several AVRs support SPI just fine. I'm using an Accelerometer on an ATmega168' I2C Bus, because I need the SPI for something else. In my case it's a ST LIS3L02DQ. Which can speak SPI as well as I2C. > I have not done electrical design in a > while.

I got a sample of http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3879 If you buy it, it'll take your about US$32.- It already comes with example code for several USB Enpoints (UMS, HID, CC) and a little Windows Demo application as an appetizer. > this was the chip I > found but I did not know where the price was. > http://www.vti.fi/en/products-solutions/products/accelerometers/sca3000-accelerometers/ Seems to work. > I would be willing to barter also some software engineering time for > some electrical design or board layout. I have 20 years in software. Business stuff is off-topic here. So, no offer from me. ;-) Regards, Clemens Koller __________________________________ R&D Imaging Devices Anagramm GmbH Rupert-Mayer-Straße 45/1 Linhof Werksgelände D-81379 München Tel.089-741518-50 Fax 089-741518-19 http://www.anagramm-technology.com _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
