Function Documentation

◆ Flash_Dump()

void Flash_Dump	(	std::vector< std::tuple< uint16_t, uint16_t > > *	result,
		bool	includeAll )

Definition at line 268 of file flash_helpers.cpp.

◆ Flash_Format()

bool Flash_Format ( )

Erases the whole EEPROM to its default value

Definition at line 36 of file flash_helpers.cpp.

◆ Flash_Init()

__weak bool Flash_Init ( )

Called after startup

Definition at line 46 of file flash_helpers.cpp.

◆ Flash_InvalidateDataCache()

static void Flash_InvalidateDataCache ( )

static

Formats the eeprom emulation section to delete all data Invalidate the ART data cache after flash operations. The STM32F4 ART accelerator caches flash reads on the D-bus. After erasing or programming flash, stale cached values would be returned unless the cache is explicitly reset. (See ST AN3969)

Definition at line 30 of file flash_helpers.cpp.

◆ Flash_Read() [1/2]

__weak bool Flash_Read	(	uint16_t	adr,
		uint16_t *	buf )

Definition at line 254 of file flash_helpers.cpp.

◆ Flash_Read() [2/2]

bool Flash_Read	(	uint16_t	adr,
		uint16_t *	buf,
		bool	checkempty )

Reads a value and if checkempty is true returns false if the read value is the erased value (0xffff) or not found

Definition at line 95 of file flash_helpers.cpp.

◆ Flash_ReadWriteDefault()

bool Flash_ReadWriteDefault	(	uint16_t	adr,
		uint16_t *	buf,
		uint16_t	def )

Definition at line 105 of file flash_helpers.cpp.

◆ Flash_Write()

bool Flash_Write	(	uint16_t	adr,
		uint16_t	dat )

Definition at line 65 of file flash_helpers.cpp.

◆ Flash_Write_Defaults()

void Flash_Write_Defaults ( )

Writes factory default values to flash. Does nothing if no defaults are defined

Definition at line 380 of file flash_helpers.cpp.

◆ I2C_EEPROM_Read16()

bool I2C_EEPROM_Read16	(	uint16_t	devAdr,
		uint16_t	adr,
		uint16_t *	buf,

Helper function to read 16b data from i2c eeproms with different block sizes

Definition at line 173 of file flash_helpers.cpp.

Definition at line 137 of file flash_helpers.cpp.

◆ OTP_Read()

__weak bool OTP_Read	(	uint16_t	adroffset,
		uint64_t *	dat )

Definition at line 318 of file flash_helpers.cpp.

◆ OTP_Write()

__weak bool OTP_Write	(	uint16_t	adroffset,
		uint64_t	dat )

Definition at line 298 of file flash_helpers.cpp.
