Re: warning: internal error: unsupported relocation error

Anybody can provide some further suggestion? I truly appreciate your help.

Is there are way to cause gcc to cough up a link table?

Otherwise, perhaps some experimental code removal could
focus in on where the problem lies.

Reg ADC.getdata( )


Hi all,

      What will be the output of ADC.getdata( ) ? Is it the raw voltage value of the sensor  connected to the corresponding ADC channel or the calibrated sensor reading? Plz help me...

Awaiting the answer,
Malini.

The function sendDone of the application " BlinkToRadio" ( TinyOs 2.1) don't match , so the receive function also don't match.

Encoding

Hello all,

In tinyos-1.x, encoding option(s) is provided by 
  • RADIO_BYTE.comp
  • FOUR_B_RADIO_BYTE.comp
  • SEC_DED_RADIO_BYTE.comp
and all. These are not available in tinyos-2.x!!! What are the alternate of these??

Please help!!..
Thanks in advance

Re: invalid operands to binary ^

What you are trying to do, is to XOR 2 pointers to message_t structs.
What is the logic here?

I tried something like this and got the XOR to compile:

       struct *x;
       struct *y;
       int z = ( (int)x ^ (int)y );

Re: ways to multicast

You can't multicast. Only broadcast or unicast.

Hello,

I would need some help...
Does anyone know what these two AM types exactly mean? 
 1) MODE_ONE_HOP_BROADCAST
 2) AM_ANY2ANY
And if I can use them in the MhopSend Interface to multicast to some nodes?
If i cannot use them to multicast, could you help in how can i achieve that?

Thank you in advance

I am trying to implement a routing/aggregation protocol on Tmote-sky nodes.
 
first of all, i'd like to know How to send messages to all the nodes on the network. which interface should I use to create messages?
and is there a way to save a metric on the nodes individually, or any efficient way to let the motes remember that value.
 
I appreciate you help and thank you in advance.

Re: invalid operands to binary ^

I think you should, as suggested above, explain what your code should do. Because you are doing some, in my oppinion, strage things here.
For example this line of code:
(++radioIn >= 2) && (radioIn = 0) ;
doesnt make sense when written as a statement. You will add one to radioIn and set radioIn to zero while doing a logic and (?).
And one other thing:
for (j=0;j<=9;j++)  
{  
  line_a[j]=radioQueue[radioOut];
}
You are accessing 10 elements in line_a, but it only has 2 elements?
And the final question: why do you want to xor 2 message_t struct pointers. If everything is correct then I guess casting the pointers to ints as suggested by Michael would do the job.
