Functions | |
| void | TLx4966_Config (TLx4966_Handle_t *handle, uint8_t polesPair, TLx4966_PowerMode_t powMode, TLx4966_MeasMode_t measMode, TLx4966_SpeedUnit_t speedUnit, TLx4966_HwIntf_t *hwIntf) |
| Configures the sensor handle attributes Mandatory hw interfaces: dir, speed, timer. Optional hw interfaces: power (only for switch mode platform). | |
| TLx4966_Error_t | TLx4966_Init (TLx4966_Handle_t *handle) |
| Initilializes the hardware interfaces. | |
| STATIC void | TLx4966_DirectionCallback (TLx4966_Handle_t *handle) |
| Direction interrupt callback The sensor instance direction is updated upon interrupt event: rising or falling edge. | |
| STATIC INLINE void | TLx4966_CalculateSpeed (TLx4966_Handle_t *handle) |
| Calculates the speed The rising edge of the speed GPIO signal determines the rotating period between a pair of poles. The speed is then obtained by applying the selected speed unit product coefficient, and dividing between the number of poles pairs. | |
| STATIC void | TLx4966_SpeedCallback (TLx4966_Handle_t *handle) |
| Speed interrupt callback The sensor instance instant speed is updated upon rising edge. | |
| TLx4966_Error_t | TLx4966_Enable (TLx4966_Handle_t *handle) |
| Enables the sensor. | |
| TLx4966_Error_t | TLx4966_Disable (TLx4966_Handle_t *handle) |
| Disables the sensor. | |
| void | TLx4966_UpdateSpeed (TLx4966_Handle_t *handle) |
| Updates the sensor speed. A rising edge is detected when the gpio voltage level changes from low to high. | |
| INLINE void | TLx4966_UpdateDirection (TLx4966_Handle_t *handle) |
| Updates the rotation direction A rising edge is detected when the gpio voltage level changes from low to high. | |
| INLINE void | TLx4966_UpdateValues (TLx4966_Handle_t *handle) |
| Updates the rotation direction and speed. | |
| INLINE void | TLx4966_GetValues (TLx4966_Handle_t *handle, TLx4966_Params_t *params) |
| Gets the rotation direction and speed parameters. | |
| INLINE TLx4966_Status_t | TLx4966_GetStatus (TLx4966_Handle_t *handle) |
| Gets the sensor status. | |
| INLINE double | TLx4966_GetSpeed (TLx4966_Handle_t *handle) |
| Gets the rotation speed. | |
| INLINE TLx4966_Dir_t | TLx4966_GetDirection (TLx4966_Handle_t *handle) |
| Gets the rotation direction The direction definition (clock-wise/anticlock-wise, left/rigth, positive/negative...) is dependant of the mechanical configuration of the sensor with repect to the rotor. The library just provide voltage-low/voltage-high directions. | |
Variables | |
| STATIC double | TLx4966_SpeedCoeffient [3] |
