Drive.H
haptic ERM/LRA driver
The Drive.H tile is designed for driving linear-resonant actuators (LRAs) or eccentric rotating-mass motors (ERMs) using the Texas Instruments DRV2605 IC. Haptic signals can be generated either from an internal effects library, streamed in real time over I2C, or input as a high-speed pulse-width modulation (PWM) signal. Additionally, an optional hardware trigger can be used to play back pre-configured effects. Separate logic and motor supply connections allows for digital interfacing with logic down to 1.8V.
