A LRA has a weight and magnet suspended by springs and a voice coil. When the drive signal is applied, the weight would be vibrate on a single axis (side to side or up and down). Since the weight is attached to a spring, there is a resonance effect at a specific frequency. This frequency is where the LRA will operate the most efficiently. Refer to the motor's datasheet for the recommanded range for this frequency. ```c -#define FB_ERM_LRA 1 -#define FB_BRAKEFACTOR 3 /* For 1x:0, 2x:1, 3x:2, 4x:3, 6x:4, 8x:5, 16x:6, Disable Braking:7 */ -#define FB_LOOPGAIN 1 /* For Low:0, Medium:1, High:2, Very High:3 */ +#define DRV2605L_FB_ERM_LRA 1 +#define DRV2605L_FB_BRAKEFACTOR 3 /* For 1x:0, 2x:1, 3x:2, 4x:3, 6x:4, 8x:5, 16x:6, Disable Braking:7 */ +#define DRV2605L_FB_LOOPGAIN 1 /* For Low:0, Medium:1, High:2, Very High:3 */ /* Please refer to your datasheet for the optimal setting for your specific motor. */ -#define RATED_VOLTAGE 2 -#define V_PEAK 2.8 -#define V_RMS 2.0 -#define V_PEAK 2.1 -#define F_LRA 205 /* resonance freq */ +#define DRV2605L_RATED_VOLTAGE 2 +#define DRV2605L_V_PEAK 2.8 +#define DRV2605L_V_RMS 2.0 +#define DRV2605L_V_PEAK 2.1 +#define DRV2605L_F_LRA 205 /* resonance freq */ ``` #### DRV2605L waveform library |
