Hi Amra.
In terms of your wiring of TinyDB, what you've done looks reasonable.
Typically, the problem you describe suggests that there is a problem in your getAttr() implementation -- if the wiring isn't correct, usually TinyDB will just return an empty (null) field for the attribute value. It seems most likely that the ADCReady() event is never firing in you PressureM.nc file.
How did you choose TOS_ADC_PRESSURE_PORT?
Why don't you try changing your getAttr() command to be something like:
event result_t PressureM.getAttr(char *name, char *resultBuf, SchemaErrorNo *errorNo)
{
pressure = resultBuf;
*(uint16_t*)pressure = 0xbeef;
*errorNo = SCHEMA_RESULT_READY;
return SUCCESS;
}
If this successfully returns data then you can be sure TinyDB is connected properly.

Hi all,

I am trying to add a new attribute for an external pressure sensor on basicsb. I am using TinyOS 1.1.6v.

However, seems that�I wired up something wrong. Here is what I did:
�
�
���� 1.� I created Pressure.nc and PressureM.nc files which I included in sensorboards/basicsb. Since it is analogue sensor I basically c/v the code from Photo.nc and ��������� PhotoM.nc just changing the names.�
����Pressure.nc file:
includes sensorboard;
configuration Pressure
{
provides interface ADC as PressureADC;
provides interface StdControl;
}
implementation
{
components PressureM, ADCC;
StdControl = PressureM;
PressureADC = ADCC.ADC[TOS_ADC_PRESSURE_PORT];
PressureM.ADCControl -> ADCC;
}
PressureM.nc file:
includes sensorboard;
module PressureM {
provides interface StdControl;
uses {
interface ADCControl;
}
}
implementation
{
command result_t StdControl.init() {
call ADCControl.bindPort(TOS_ADC_PRESSURE_PORT, TOSH_ACTUAL_PRESSURE_PORT);
TOSH_MAKE_PRESSURE_CTL_OUTPUT();
TOSH_SET_PRESSURE_CTL_PIN();
dbg(DBG_BOOT, "PRESSURE initialized.\n");
return call ADCControl.init();
}
command result_t StdControl.start() {
TOSH_MAKE_PRESSURE_CTL_OUTPUT();
TOSH_SET_PRESSURE_CTL_PIN();
return SUCCESS;
}
command result_t StdControl.stop() {
TOSH_CLR_PRESSURE_CTL_PIN();
return SUCCESS;
}
}
� ��� 2.� I created the attribute files (AttrMoto.nc and AttrMotoM.nc) � ��� ��� ��� AttrMoto.nc: ���������������
configuration AttrMoto {

What happens is,�if I select only nodeid�from GUI I can get the nodeid back. However If I choose nodeid and pressure attributes in GUI I cannot even get the nodeid back. I tested the pressure sensor using temp.nc file and "temp" attribute wiring the pressure sensor on the temp ADC port and it worked fine, so it is not a HW problem.
Any ideas, suggestions?
