I would like to share some problems using the "Sketch Examples" for the CF Card by LC Studio. I was currently trying to use the CF Card using the Examples\SD\Datalogger, CardInfo, etc and I could not make it work. The card would not initialize at all. After doing some research and some experimenting, the CS (ChipSelect) must be configured to 10 as the PinMode for pin 10 is set as Output (this can not be change due to the SD library). So if you change the CS to 10 on the Sketch to match the PinMode, it should work for the CF Card made by LC Studio. I hope this helps since LC Studio does not have a code example for this CF Card.
/*
SD card test
This example shows how use the utility libraries on which the'
SD library is based in order to get info about your SD card.
Very useful for testing a card when you're not sure whether its working or not.
The circuit:
- SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.
Pin 4 used here for consistency with other Arduino examples
