SPI MicroSD Card Software


I have looked through all the post on all forums, and I do not find any spi microSD software. I know it is slower, but the hardware I am using is a datalogger with a spi interface using the USBizi chip.

Any help would be appreciated.


Usbizi connects to sd directly so why do you need spi on sd?!


Because that is the way the logger was built.


You have a logger that connects to sd do then why usbizi is needed? And on sd?! What will usbizi do?


@ bdrew, the simple answer is you can’t use the inbuilt SD capability and file system that the GHI stack provides if you want to use an SPI device (that happens to be an SD card). You need to write/abstract your own SPI/file IO.
