SDCard Driver for the SPI bus

In Windows CE you can already find an SDCard stack, that allows you to use different kind of cards on several MMC/SDCard controllers. Possibly you will ask yourself, what new kind of things we have to offer for you.

Did you know, that you can use SD storage cards also on an SPI bus? Possibly this is not very much of interest for you, if your chipset already contains an MMC/SD controller. If this is not the case, then you can still access SD memory cards when you connect the cards to an SPI bus. The problem with that approach is unfortunately, that no driver exists under Windows CE that handles such a configuration.

We have developed a special driver, that allows you to access SD memory cards on the SPI bus. The performance results are quite good compared to the existing MMC/SD controller solutions. The driver has been tested with lots of different cards, so that we can guarantee a high level of compatibility. Besides the usual SD cards, we also support the SDHC standard, so that you can also use SD cards larger than 2 GB.
