<p>I just completed a project using the LPC2132 chip, but ran into problems with using up the whole 64kb of RAM. </p> <p>For my next project, I'd like to use something that can reference an external, much larger memory chip. What sort of ARM can do this and what do I need to do to get the two devices talking?</p>

<p>I've been considering using a NANDrive by SST in a new design, however I wasn't sure how complicated it would be to connect a PIC to the ATA interface on the NANDrive. I did a quick Google search and found a couple of forums with people who had done it, but I was wondering if anyone here had experience with it and could suggest a standard software library for PIC C18 that implements ATA.</p>

<p>I was just wondering if there was a tutorial anywhere on how to make your own USB Flash Drive and I don't mean take apart a USB and put the guts into something else, I mean put together the flash memory and controller.</p>

<p>I've seen news articles talking about how SanDisk released Write Once Read Many (WORM) SD cards, but I can't find anywhere to buy them!</p> <p>I'm thinking of building a project where I'll want to write reasonably small amounts of data (amounting to maybe 64 MB at most) to permanent storage, for retrieval via USB — can anyone think of a suitable IC for this?</p>

<p>Hey,</p> <p>Got a new MicroSD shield from LittleBird, having some troubles with it,</p> <p>Downloaded the sample library that it said to used threw in a MicroSD card and expected it to work... It won't initialise for some reason done a bit of googling and can't see how to get it working every one just say use this library, uses that one.</p> <p>Anyone had any luck on get these set up</p> <p>Hardware</p> <ul> <li>MicroSD Shield</li> <li>Arduino Duemilanove (ATMEGA328)</li> <li>SanDisk (4GB) MicroSD card (HC) </li> </ul> <p>Is the SDHC part the problem?</p> <p>I work off a mac even formatted the card in a Win XP machine to fat 16 still no luck</p>

<p>Is there a good book that talks about memory (SDRAM, DDR, NVRAM, flash etc) from a hardware/system perspective? Most of what I've been able to find deal with memory at the transistor level. I am looking for overview of the different types of memories, power requirements and PCB guidelines.</p>

<p>I'm using an ATTiny2313 to act as a serial concentrator. It only has 128bytes of RAM. I think I'm running out of RAM during the ISR. My question is how much RAM (stack) does an ISR use to save the context (registers). I.e. if I use ISRs how much will I have left out of 128 bytes. Is there a way to detect stack overflow?</p>

<p>Is it possible to save data from the Arduino to a SD Memory module?</p>
