Haptic Drivers
Low-Power, High-Definition Haptic Drivers: the Buzz in Next Generation Human-Machine Interfaces
Dialog Semiconductor’s DA728x family High-Definition (HD) Haptic Driver provides drive capability at up to 1kHz to cover the broad range of human touch sensitivity. With market-leading idle current consumption (360nA), Linear Resonant Actuator (LRA) resonant frequency tracking capability, and low latency for tact button replacement applications, the DA728x family creates a buzz in smartphones, gaming platforms, wearables, and similar systems.
Powering the Next Generation of Haptic Experiences
Haptic actuators and motors are diversifying at a rapid pace. Gone are the days of simple coin-cell type LRA motors and small ERM (Eccentric Rotating Mass) pager motors. 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 500mA of current.

Is there any available source code in langue C for driving DA7280?
Posted byKyle07910 points 2 repliesHi,
I am trying to build an STM32 based embedded system using the DA7280 chip to control a vibration motor.
Is there any available source code in langue C for driving the chip?
Best,
Kyle

Just to add a comment (posted as we transitioned from old forum) :
"
John is right. There isn't anything available in vanilla C, however, there is some available Arduino libraries available at:https://www.arduino.cc/reference/en/libraries/haptic_da7280/
This was not created by Dialog, nor is it maintained by Dialog, but it may serve as an excellent start to development.
In addition, we also have Linux and HAL (Hardware Abstraction Layer) drivers available. The Linux driver has recently been accepted into the latest Kernel, and the Hardware Abstraction Layer driver for embedded systems is attached.
We'd love to know more about your application, please do reach out if we can help further.
Best Regards"
