[Tinyos-help] why Leds component doesn't work on Tmote invent platform

[yicheng]

Is there any difference in the circuit between Tmote Sky DAC0 and
Tmoteinvent DAC0? I made my own amplifier and speaker, can I just use the
DAC output part of SpeakerDriverC on Tmote Sky? If not, how should I adapt
it to Tmote Sky? Btw, what is the AD524XC component in SpeakerDriverC?
Thanks!

No, the Tmote Invent speaker uses a different circuit (see the Tmote
Invent User's Guide at www.moteiv.com for more information).
