We are a few friends building a robot, and we are going to need more memory than is available in the microcontroller.
so we thought it would be smart to use a external flash memory, which can then also be moved to a computer to upload test data.
I happen to have a spare Sandisk m2 2GB flash memory, but we’ve faced problem on finding developer information such as the communication protocol, what pins to use and such.
we have been searching a lot for datasheets for this but’ve come up short.
is there a way of getting my hands on this information without paying crazy prototype fees like the 1000$ the http://www.sdcard.org/developers/howto/ mention for specifications on the cards for companies in their R&D phase?
FYI we are using an Atmel Xmega 1281A
we are going to feed the flash card with 3.3V, so the 1.8V mode it NOT used
