haptic hardware driver

So from what I understand neither the bangle 1 or 2 or any supported bangle device has a haptic driver. But devices like the pebble watch had a haptic driver. https://www.ti.com/lit/ds/symlink/drv260­3.pdf?ts=1711575201075

Is there anything that would be useful to have this piece of hardware or is a properly configured pulsed pin perfect for most use cases.

So I actually think I misunderstood that chip for this chip. https://www.ti.com/product/DRV2605

Which has a library of different haptic effects

There is a vibration motor which is turned on/off by toggling GPIO pin. You can set it or use PWM (analogWrite) to use it as you wish. Not sure what you are after. No other 'haptic hardware/driver' is there AFAIK.

Not really after anything. Just saw this chip from TI(2605) that does some fancy haptic effects and just wondering if they were at all useful for a watch.

I've only had one example with this kind of thing on my Samsung s3. I had this meditation app that would have this cool ramp up vibration. The kind of ramp that would be a pain to make in software. But i dont know other cases where I know there was some fancy vibration on my watch.

There's a library at https://github.com/espruino/BangleApps/b­lob/master/modules/buzz.js (and associated menu item at https://github.com/espruino/BangleApps/b­lob/master/modules/buzz_menu.js) which allows you to choose from a set of different buzz patterns.

I can understand maybe you want something fancy when driving an iPhone style haptic vibrator that's more like a voice coil than a motor, but when driving a motor, I think you can do whatever you want to do just by pulsing the GPIO pin in the right way, which can be done in software like above?
