Hi
I've been working with a driver for the sht11 on MTA300, adapted from TelosB by
Javier Almansa Sobrino. I'm using it in an IRIS mote.
It seems to be reading the sensor; my next step was trying to print some values
with printf.
The problem is that if I add (just add, commented in the code) CFLAGS
+= -I/opt/tinyos-2.x/tos/lib/printf to the makefile the red blinks!!!!
It seems that some code in the printf library just creates the problem, but
I'm not so sure...
Regards,
André

call Leds.led2Toggle();

Hi,
You can have a java application to read what comes into the coordinator and
then connect to probably a database like MySQL. There are so many examples for
java application in TinyOS in the apps section.
The other way that you can write the received data to a text file is by using
the 'Listen' or 'MsgReader' something like:
java net.tinyos.tools.Listen > coordinator.txt
OR
java net.tinyos.tools.MsgReader CoordinatorMsg > coordinator.txt (where
Coordinator Msg is the message you generate in your java application)
Cheers,
