Pivumeter - change brightness on the fly


#1

Is it possible to change the brightness of the LEDs on the Phat Beat vu on the fly? I’d like to make them respond to ambient light conditions (I.e. be dimmed in a darn room, bright in a well lit one).
I can hook up an LDR to get ambient light (or just use the envirophat) but it seems that brightness is a config setting and I am doubtful that it would be dynamically updated just by changing asound.conf.
Thanks
Marc.

well, the asound is scanned when an application creates a stream i.e starts playback, so any changes to the brightness setting would take effect at some point, albeit not ‘on-the-fly’.

… if you play a continuous stream like a radio then it would be difficult, not to say impossible (with the current pivumeter implementation at least).

Okey doke. Thanks for the reply.
