I think what you need to do is have separate names for each ADC 'channel'
and call their getData()'s in sequence, something like this:
in the Config file:
ProjectOtherM.ADCx -> ADCC.ADC[TOS_ADC_SENSORX_PORT];
ProjectOtherM.ADCy -> ADCC.ADC[TOS_ADC_SENSORY_PORT];
ProjectOtherM.ADCz -> ADCC.ADC[TOS_ADC_SENSORZ_PORT];
(I'm not sure about your ASSOCIATE_ADC_CHANNEL() stuff, on micaX's
under T1 I simply use the channel number. Is this perhaps T2, or
else I'm still unfamiliar with Tmote specifics...?)
in the code:
after startup or in your timer.fired():
call ADCx.getData();
Then chain the gets in the individual Ready() methods:
// get data from X channel and fire off Y channel conversion
async event result_t ADCx.dataReady( uint16_t data )
{
...
call ADCy.getData();
return SUCCESS;
}

I want to get three value from tmote sky.I use 3-axis accelerator
sensor, and I need the X, Y, Z Output.
I'm unable to get three values at one time, so i try to get one value
at one time, then get three times to be a cycle.
(If anyone get some solutione like get three values at one time, please
tell my how to do.)
This program seems to get only one value.Please help me to solve this
problem.
