I want to build an small data logger based around ATMEL's 8535 (or one of the AVR Mega). I need to log around 300MBytes of data. USB memory sticks are cost effective storage mediums. Is there a simple way to interface a USB memory stick with an ATMEL microcotroller? Ray

There's something a bit sad about using a double-digit MHz 128K 32-bit processor to interface an 8-bit micro with a USB flash drive, but I bet that could be pretty useful in some circumstances.

The SD/MMC is easier to connect to the AVR but will require a memory reader on most PCs. Check www.avrfreaks.net. There is someone which has a ready application for SD connection and sells the source code etc. for about $130 I think they use a mega128. A part with external bus might be good if you want to use Compactflash. -- Best Regards, Ulf Samuelsson This is intended to be my personal opinion which may, or may bot be shared by my employer Atmel Nordic AB
