Hello,
i am new to tinyos programming. i am using a telosb plattform called Kmote.
I have problems with the ADC. unfortunatley i cant post my entire code in
zip format so i posted the entire code. i have a temperature sensor in
combination with a operational amplifier and the ouptut is connected to the
ADC2 chanel.
I have posted my entire code. Both, the configuration file and the module
file. i dont understand why i am getting values around 932 even if i unplug
the cable from the ADC's input.
the small project i am trying to implement is that i send a sensor value
from one board to another one, which displays me that on the terminal. what
i am doing wrong?
i am thankful to any advice you can give me...
regards,
Kmote
