loadConfig()

void loadConfig

(

void

)

Load all config tables from storage.

Here is the call graph for this function:

Here is the caller graph for this function:

readCalibrationCRC32()

uint32_t readCalibrationCRC32

(

uint8_t

calibrationPageNum

)

Retrieves and returns the 4 byte CRC32 checksum for a given calibration page from EEPROM.

Parameters

calibrationPageNum

- Config page number

Here is the call graph for this function:

Here is the caller graph for this function:

readEEPROMVersion()

uint8_t readEEPROMVersion

(

void

)

Read EEPROM current data format version (from offset EEPROM_DATA_VERSION).

readLastBaro()

byte readLastBaro

(

void

)

Read last stored barometer reading from EEPROM.

Here is the caller graph for this function:

readPageCRC32()

uint32_t readPageCRC32

(

uint8_t

pageNum

)

Retrieves and returns the 4 byte CRC32 checksum for a given page from EEPROM.

Parameters

pageNum

- Config page number

Here is the call graph for this function:

resetConfigPages()

void resetConfigPages

(

void

)

Reset all configPage* structs (2,4,6,9,10,13) and write them full of null-bytes.

Here is the call graph for this function:

Here is the caller graph for this function:

storeCalibrationCRC32()

void storeCalibrationCRC32	(	uint8_t	calibrationPageNum,
		uint32_t	calibrationCRC
	)

Same as above, but writes the CRC32 for the calibration page rather than tune data

Parameters

calibrationPageNum	- Calibration page number
calibrationCRC	- CRC32 checksum

Here is the call graph for this function:

Here is the caller graph for this function:

storeEEPROMVersion()

void storeEEPROMVersion

(

byte

newVersion

)

Store EEPROM current data format version (to offset EEPROM_DATA_VERSION).

Here is the caller graph for this function:

storeLastBaro()

void storeLastBaro

(

byte

newValue

)

Write last acquired arometer reading to EEPROM.

Here is the call graph for this function:

Here is the caller graph for this function:

storePageCRC32()

void storePageCRC32	(	uint8_t	pageNum,
		uint32_t	crcValue
	)

Write CRC32 checksum to EEPROM. Takes a page number and CRC32 value then stores it in the relevant place in EEPROM

Parameters

pageNum	- Config page number
crcValue	- CRC32 checksum

Here is the call graph for this function:

writeAllConfig()

void writeAllConfig

(

void

)

Write all config pages to EEPROM.

Here is the call graph for this function:

Here is the caller graph for this function:

writeCalibration()

void writeCalibration

(

void

)

Write calibration tables to EEPROM. This takes the values in the 3 calibration tables (Coolant, Inlet temp and O2) and saves them to the EEPROM.

writeCalibrationPage()

void writeCalibrationPage

(

uint8_t

pageNum

)

Here is the call graph for this function:

Here is the caller graph for this function:

writeConfig()

void writeConfig

(

uint8_t

pageNum

)

Write a table or map to EEPROM storage. Takes the current configuration (config pages and maps) and writes them to EEPROM as per the layout defined in storage.h.
