Hi everyone,
I have an application that performs several readings consecuitves with
different ports of the ADC. Specifically, first read the internal voltage of
the microcontroller IRIS, and then performed a reading of a temperature
sensor that I have connected. To make both readings the results a
Hello all,
I have a problem with the IRIS platform. When I do readings of different
channels of ADC reading the microcontroller's internal voltage (channel
ATM128_ADC_SNGL_1_23) the event (dataReady) is SUCCESS but the reading
(data) is erroneous. I have cheked that if I make two consecutive readin
Antonio,
I have a guess what can be wrong. I assume you're using either the
Atm128AdcSingle or Atm128AdcMultiple interface. While the dataReady
event is slightly different in these two interfaces, in each cases it
has a bool parameter, not an error_t. Notice that the value of the
SUCCESS constant
Antonio,
I have been able to replicate this. Interestingly, only the first
sample should be bad after a channel/vref change according to the data
sheet, unless we're switching to a differential channel, where it may
take up to 125us for the stage to stabilize. I did observe, however,
that the seco

Thanks for all, Antonio Rosa.
Maybe I will send you some questions about others topics, that I think there
is problems o bugs.

Hi Janos,
I have been that the component ActiveMessageLayerP of rflink/layers library
provides interface Receive[am_id_t id]. The event SubReceive.receive that
signal Receive.receive event not filter the group, and this produces that
any node with the same id but different group can receive the
Hi Antonio,
That is a good catch. I think the isForMe should be fixed. It is also
a good question whether messages with DIFFERENT group id should be
snooped. I think those messages should be dropped (that way you can
separate different apps completely, even if they use the same
services). What do
In practice, how often are parallel nets using group id to differentiate
implemented. How useful is this really. Note that
any node that is listening burns the energy to receive these packets that
they then throw away.
It is much better to put parallel nets on dfifferent frequencies.
So how u

I think that in a classroom or a building with several apartments per
florr( like a WPAN or BAN), if every apartments has a WSN maybe two o more
networks can share the same radio channel and this could be a problems for
the applications of the nodes.

Ok, I have checked in a fix: isForMe now checks the group id, and now
it is compatible with 1.x. Miklos

Miklos,
I think that also, you should include it in the command command bool
AMPacket.isForMe(message_t* msg) provides by ActiveMessageLayerP on library
/tos/chips/rf2xx/layers.

That is done automatically, since there we call Ieee154PacketLayerP. Miklos
