Haptic driver lra

 · As the product name itself says, this tiny board combines the Haptic motor driver (DRVL) and the rectangle LRA motor. So they can work together directly. The rectangle LRA motor on board, compares to the round LRA motor, the vibrations are directed in only the Z-axis. Today’s haptic actuators offer different experiences for different markets. Whether it’s a small pancake LRA for a smart-watch or a large, or a multi-directional, LRA for gaming controllers, Dialog’s patented current drive outputs support all of these motors with up to mA of current.  · Haptics driver IC powers eccentric rotating mass, linear resonant actuator motors The Tinker’s Toolbox – Eric Siegel of TI on Haptics Feedback in Touch-Enabled Devices Desktop Development Kit enables textures/haptic effects defined by software.

Introducing the Haptic Motor Driver. Ready to add some good vibes to your project? Look no further than the Haptic Motor Driver. This board breaks out Texas Instruments' DRVL haptic motor driver, which has some seriously cool features. Add meaningful feedback from your devices using the Haptic Motor Driver and an Arduino compatible device. The DRV is a haptic driver designed for Linear Resonant Actuators (LRA) and Eccentric Rotating Mass (ERM) motors. It provides many features which help eliminate the design complexities of haptic motor control including reduced solution size, high efficiency output drive, closed-loop motor control, quick device startup, and auto-resonance frequency tracking. LRA – Linear Resonant Actuators. These actuators consist of a magnetic coil that pushes a mass up and down to create vibrations, enhanced by a spring. LRAs come in similar form factors to ERMs, and the linear motion they create gives the LRA a more directed and cleaner-feeling output than ERMs.

Apr Again, Texas Instruments offers a piezo-specific haptics-actuator driver IC. Their DRV is a single-chip piezo haptic driver with integrated. Arduino library support for the SparkFun Qwiic Haptic Driver to control Dialog Semiconductor's DA motor driver IC and the built-in LRA vibration motor. LRA's typically offer improved haptic performance with short lag and rise times, an important consideration for simulating short duration – high frequency tasks.
