Function Documentation

◆ FRAM_Initialize()

void FRAM_Initialize ( void  )

Initializes the addresses to be written in the FRAM.

This function must be called before any use of the FRAM.

Definition at line 88 of file fram.c.

◆ FRAM_Read()

STD_RETURN_TYPE_e FRAM_Read ( FRAM_BLOCK_ID_e  blockId)

Reads a variable from the FRAM.

This function reads the variable corresponding to the ID passed as parameter. Read can fail if SPI interface was locked.

Parameters
blockIdID of variable to read from FRAM
Returns
STD_OK if read was successful, STD_NOT_OK otherwise

Definition at line 160 of file fram.c.

◆ FRAM_Write()

STD_RETURN_TYPE_e FRAM_Write ( FRAM_BLOCK_ID_e  blockId)

Writes a variable to the FRAM.

This function stores the variable corresponding to the ID passed as parameter. Write can fail if SPI interface was locked.

Parameters
blockIdID of variable to write to FRAM
Returns
STD_OK if write was successful, STD_NOT_OK otherwise
