[Tinyos-help] [Tinyos-devel] DS2411 Driver development

[JD]

HI guys,

In the file /tos/chips/msp430/pins/HplMsp430GeneralIOC.nc
we have the following lines :

#ifdef __msp430_have_port2
  provides interface HplMsp430GeneralIO as Port24;
// Port24  used for OneWire Protocol

#ifdef __msp430_have_port2
    .
    .
    new HplMsp430GeneralIOP(P2IN_, P2OUT_, P2DIR_, P2SEL_, 4) as P24,
   .
   .

But we don't see any initialization of  P2IN_, P2OUT_, P2DIR_, P2SEL_
parameters. Could it be the reason of the 0xFF values we keep getting for
the ds2411's serial Id  ?

Cheers,

JD
