BLDC Haptics

The BldcHaptics class is a high-level interface for controlling a BLDC motor with a haptic feedback loop. It is designed to be used to provide haptic feedback as part of a rotary input device (the BLDC motor). The component provides a DetentConfig interface for configuring the input / haptic feedback profile for the motor dynamically with configuration of:

  • Range of motion (min/max position + width of each position)

  • Width of each position in the range (which will be used to calculate the actual range of motion based on the number of positions)

  • Strength of the haptic feedback at each position (detent)

  • Strength of the haptic feedback at the edges of the range of motion

  • Specific positions to provide haptic feedback at (detents)

  • Snap point (percentage of position width which will trigger a snap to the nearest position)

The component also provides a HapticConfig interface for configuring the haptic feedback loop with configuration of:

  • Strength of the haptic feedback

  • Frequency of the haptic feedback [currently not implemented]

  • Duration of the haptic feedback [currently not implemented]
