drv2605l

[NOTE: This is actually a fork of Jacob Rosenthal's excellent library, which itself is a fork of Wez Furlong's excellent library. I'm eternally grateful to both]

This module implements a driver for the drv2605l, a Haptic Driver device addressable via I2C from Texas Instruments.

Its rather fully featured implementation for both LRA and ERM motors including:

• Internal rom library sequencing and playback
• Pwm playback at the in/trig pin
• Real time playback over i2c commands
• Analog voltage input at the in/trig pin

A few things are not supported at the time of this writing:

• bidirectional input
• choosing loop operation. The prefered and far more common closed loop operation is hardcoded except for the case of ERM rom libraries which require open loop.
• audio to vibe mode
• external trigger mode

This work originated in the drv2065 driver and may be able to unify someday.
