Texas Instruments’ Haptic Bluetooth Kit (DRV2605EVM-BT) helps enable designers to prototype eccentric rotating mass (ERM) motor and linear resonant actuator (LRA) haptic affects. Texas Instruments’ ...
Interfacing PWM logic sources to battery-powered motor drivers can be a challenge. While an Linear Resonant Actuator (LRA) is driven with an AC bipolar waveform near the LRA's resonant frequency, an ...
