Daniel Levine / CircularBufferSDCardLib

A set of data recording functions to locally store data in a circular buffer, with functions for offloading to an SD Card when convenient. dataRecorderr.h shows accessible functions to the main program - all direct SD operations are abstracted away by the library. When using this library, #include dataRecorder.h

Dependencies:   sd-driver_compatible_with_MAX32630FTHR
