Hi
Please let me know how can I save my sensor data readings from telosb into
a text file?
PFA the code I have been using. But it only displays the sensor readings on
the serial port terminal in ubuntu.
I need to take say around 1000 light sensor readings and save it in a text
file.
Please help me out in this..
Thanks
