Investigate the use of PWM control #7

Open RiccardoGrieco opened 2 years ago

RiccardoGrieco commented 2 years ago

For the haptic feedback we are currently relying on the waveform library provided by the DRV2605 driver.

The intensity of the vibrations is then limited by the available waveforms (e.g. Buzz 20, 40, 60, 80, 100%).

However, the driver allows also the PWM control, which can supposedly allow to increase the possible intensities that can be exerted.

From a preliminary discussion with @Gianlucamilani, this would require a change in the electronics for using the IN/TRIG pin.
