Logging lots of data with a BS2
Archiver
Posts: 46,084
Hi,
I may have an application that will require portable, battery-powered logging of
lots of GPS and other serial data using a BS2. At the moment, I think I'm
looking at needing between 1 and 8 Mbytes of storage. I need something
non-volatile so that in case of power interruption the recorded data isn't lost.
Any suggestions? I see that Dallas has a 2Mx8 NVRAM chip, but I need a way to
talk to it with serial commands and I'm not a PIC programmer.

MegaStore
Store up to 64Mbytes of data on MMC card
MMC card socket
3- wire SPI interface
Store in 512 byte chunks
Suitable for Stamp2s
Supplied with code examples and 8Mbyte card
Which is available from Milford Instruments (and I guess a load of other
places as well). I sort of loved the idea originally because in addition
to being non-volatile you can change the card. so the data is portable
from one machine to another (say from the logging device to a PC). I also
loved the idea that the card would fit in my mobile phone But I think from
the information I have read that the formatting would be very hard. If
you like I'll mail you the data I was sent on the device.

Also, Tern offers flashcore, which has an option for simple serial
access to CF card. I have not tried it, so I don't know how it works
in practice.

The ATMEL dataflash chips are a cheap way to get a lot of data with
the stamp, but the program driver is more "basic":
