Here is a simple example of how to read temperature using Mica 2 Sensing
board and display the most significant three bit on led.
Go to the folder /opt/tinyos-1,x/apps/SenseToLeds
Open the file file SenseToLeds.nc.
It should look like as shown below.
configuration SenseToLeds {}
implementation
{
components Main, SenseToInt, IntToLeds, TimerC, Photo;
Main.StdControl -> SenseToInt;
Main.StdControl -> IntToLeds;
SenseToInt.Timer -> TimerC.Timer[unique("Timer")];
SenseToInt.TimerControl -> TimerC;
SenseToInt.ADC -> Photo;
SenseToInt.ADCControl -> Photo;
SenseToInt.IntOutput -> IntToLeds;
}
Replace all Photo Component with Temp (The bold phase words need to be
replaced)
The code will look like
configuration SenseToLeds {}
implementation
{
components Main, SenseToInt, IntToLeds, TimerC, Temp;
Main.StdControl -> SenseToInt;
Main.StdControl -> IntToLeds;
SenseToInt.Timer -> TimerC.Timer[unique("Timer")];
SenseToInt.TimerControl -> TimerC;
SenseToInt.ADC -> Temp;
SenseToInt.ADCControl -> Temp;
SenseToInt.IntOutput -> IntToLeds;
}
Save the file
Further go to the folder
/opt/tinyos-1.x/tos/sensorboard/<your sensor board>/
Open sensorboard.h file
edit the line
TOSH_ALIAS_PIN(TEMP_CTL, INT2); to the following one
TOSH_ALIAS_PIN(TEMP_CTL, PW0); and Save it
After Compilation SenseToLeds program will monitor the temperature and three
MSBs of the ADC output will be displayed on the LEDs with LSB on Yellow and
MSB on Red.
We have used MIB510 Serial port programmer, MPR2400 Mote processor and
MTS310 Sensor Data Acquisition board.
Thanks to Yong, Chee Yeew" <[EMAIL PROTECTED]> for providing a
solution.
