[Tinyos-help] about the driver of sht11 on iris

[Janos Sallai]

I think the sht11 datasheet describes how to convert sensor readings to
metric units. Have you checked that?

Hello Janos Sallai : 

    thank you for your direction ! i have done it .

    I can get the data , for exampel  temperature , how should i change
the data to  Celsiur scale ? can you give me a formula?  and  also the
same as humility.

  

   thank you !!

Yes, you can reuse the code. The driver in /platforms/telosa/chips/sht11
is a platform independent driver. You will need to write some glue code
for your hardware platform, similar to what you can find in
platforms\telosa\chips\sht11, that describes to which GPIO and interrupt
lines the sht11 chip is hooked up on your custom hardware.

Hello all : 

    I want to use the sensor sht11 on iris platform , new the driver of
sht11 is included in the release version of tinyos-2.x , and i only find
a folder named sht11 in the directory /platforms/telosa/chips/sht11 , is
it to say that it is only used on telosa and telosb ? 

  

   If yes , can someone provide some advices on how to repot it the iris
platform ?  is it difficult ? because telosb uses Msp430 and iris uses
atmega1281 , maybe it is the key .

 

   Any advice  is welcomed . Thank you !!
