Detailed Description

Functions to save & load sensor calibration tables to/from durable storage.

This is separate from the page load as the calibrations do not exist as pages within the ini file for Tuner Studio.

Enumeration Type Documentation

SensorCalibrationTable

enum class SensorCalibrationTable : uint8_t

strong

Enum to identify sensor calibration tables.

Enumerator
CoolantSensor	The coolant sensor calibration curve.
IntakeAirTempSensor	Intake Air Temperature (IAT) sensor calibration curve.
O2Sensor	The Oxygen (O2) sensor calibration curve.

sensor

)

Retrieve the CRC for one sensor curve from durable storage.

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

saveAllCalibrationTables()

void saveAllCalibrationTables

(

void

)

Store the curves for all sensors in durable storage.

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.
