RE: [AVR-Chat] variable/constant input from a PC ? 2004-07-16 by Clark, Andy > I'm using Atmel's AT45DCB004 4MB DataFlash card, which actually uses an AT45DB321B internally. Come to think of it, Atmel's app note (AVR335) uses the 16MB chip for a digital sound recorder, check it out to see how easy the interface is. AndyC http://pages.zoom.co.uk/andyc
