Function Documentation

void InitDataStorageBuffer ( STORAGEMODE  mode  ) 

Initializes Buffer to hold data into internal memory

Parameters:
mode,: Data storage can be configured to OVERWRITE, NOVERWRITE. In OVERWRITE mode, the writing mechanism is restarted once the buffer end is reached, In NOVERWRITE the writing is stopped at the end buffer.

Reads Uint16 data from internal memory

Parameters:
data,: pointer to variable to store the read data
pos,: memory position holding the data

Definition at line 233 of file DataStorage.h.

static void ReinitDataStorageBuffer ( void   )  [inline, static]

Restart writing pointer to the starting address of the internal buffer.

Definition at line 241 of file DataStorage.h.

static void WriteData ( volatile Uint16 *  data  )  [inline, static]

Write Uint16 data to internal memory

Parameters:
data,: value to be written
Examples:

static void WriteFloatData ( volatile float *  data  )  [inline, static]

Write float value to internal memory

Parameters:
