hello. i want to know if i can connect a temperature sensor that output digital data (12 bits) to the ni elvis 2

Hi there,

what type of board are you using on ELVIS? Are you using the prototyping platform?

What type of sensor you have? Is it communicating via serial port?
Best regards,

hi . yes it communicate via serial port. how can i aquire signal from it?.i am using ds18b20 temperature sensor and the prototyping platform. how can i read the signal and convert it to temperature that will bi used in a vi in labview?

thanks a lot

Hi,

Do you have a serial port in your computer? You can use NI VISA driver to program the serial port to communicate.

Please confirm that you have a serial port in your computer.

no. i need to use ni elvis and not just directly connect the sensor to the pc. the senor has 3 wires one for the supply voltage ,one for ground and one for the data.

Hi,

You can read these data on a digital line using the Digital Reader function.

You will have to install Elvismx driver.

More details in the manual on the following link http://www.ni.com/pdf/manuals/374629c.pdf

Hello, I tested it today but it didn't work . I need something in labview that gives me 0000 0000 0001 for example and then i will convert it to the corresponding temperature ( an increment in 1 bit corresponds to 0.0625 degree C) and the sensor should be connected to the elvis 2."the sensor has a serial ouput".

thank you.
