USBmicro Misc Information #2
Rapid Application Development: Race Against the Clock
The Atmel Application Journal for Spring of 2004 has an article on development of an AVR A⁄D SPI slave device. The AVR was used to make an eight channel A⁄D device that can be used with the U4x1 so that eight channels of analog information can be gathered using this combination of devices.
The source code for this article and additional information are available here (Atmel Application Journal Zip File). The zip file contains the schematic, photos, screen captures, and device source code.
