@hackage powermate1.0

This library is for interfacing the Griffin PowerMate USB with Haskell on Linux. Besides reading events from the PowerMate, you can also control the brightness, pulse speed, and pulse waveform of the built-in LED.

(An earlier version of the library also contained an implementation of the MPD protocol. This was removed, because it wasn't directly related to the PowerMate functionality, and the libmpd library seems to be an alternative which is more complete and better maintained.)

Besides the library, this package includes two example programs, powermate-print and powermate-pulse. powermate-print simply prints out the events it receives from the PowerMate. powermate-pulse lets you control the LED pulse speed by turning the knob, and change the pulse waveform by clicking the knob.
