The iSensor-SPI-Buffer hardware platform has a SD card slot connected to SPI3. Need to develop software support for autonomous data logging to the SD card (for use in battery powered applications without a PC).

In an effort to prevent data corruption, we might be able to use the LTC4412 to detect power loss and swap over the MCU supply to a supercap backup. The proposed supercap is CPH3225A-2K.

Software support in progress. Should be mostly done, having issue getting SD card to mount correctly.

Finally done!!! Want to resolve USB data corruption issues, then will push a firmware rev 2.0 release with this data logging feature
