Is it possible to interface an SD card to LPC214x? Is it easier to work with the LPC1767/8 which already has a SD card interface? I know the Olimex board comes with an SD card connector, has anybody used it?
The free documentation also describes a "simplified" protocol on the SD interface:
www.sdcard.org/.../
but it still seemed to me to be more involved than the protocol over SPI.
Maybe I should rephrase...I want about 1 Mb space to store data and which will be erased almost continuously. So should I try to interface an SD card or go for EEPROM? Thanks for your pointers about SD interfacing.
that's not a "rephrase" - that's a total change of subject!
"... will be erased almost continuously. So should I try to interface an SD card or go for EEPROM?"
Neither!
Neither of them is really suited to continuous erasing!
If it's only 1MB, wouldn't SRAM do?
How about FRAM?
