tle5012b_util.hpp - core support header for the TLE5012B angle sensor.
GMR-based angle sensor for angular position sensing in automotive applications Author Infineon Technologies AG Copyright 2019-2020 Infineon Technologies AG Version 3.1.0 This file includes the registry definition macros of all Sensor registers and the bit settings for each of the register content values. Depending on the type of secondary interface (PWM, IIF or HSM) the meaning of some register values differs, so please have look in the TLE5012 manual for the exact meaning.

Enumeration Type Documentation

errorTypes

enum errorTypes

Error types from safety word.

Enumerator
NO_ERROR	NO_ERROR = Safety word was OK.
SYSTEM_ERROR	SYSTEM_ERROR = over/under voltage, VDD negative, GND off, ROM defect.
INTERFACE_ACCESS_ERROR	INTERFACE_ACCESS_ERROR = wrong address or wrong lock.
INVALID_ANGLE_ERROR	INVALID_ANGLE_ERROR = NO_GMR_A = 1 or NO_GMR_XY = 1.
ANGLE_SPEED_ERROR	ANGLE_SPEED_ERROR = combined error, angular speed calculation wrong.
CRC_ERROR	CRC_ERROR = Cyclic Redundancy Check (CRC), which includes the STAT and RESP bits wrong.
