Sensirion SHT11 vi, or pulse train(?) help

[MikeB]

I am fairly new to Labview and request help!

I have a PCDIO-24 board and Labview 6.0.

I am trying to interface with a Sensirion SHT11 humidity & temp
sensor. If anyone has a vi I could use as an example, great!, if not
then: how do I send a series of digital pulses to the sensor? There
are 2 digital inputs to the sensor; a clock input and a read/write
input/output (bidirectional). I need to generate and send different
data and clock pulses at the same time to both inputs (and also read
the returned pulse signal). I just want to be able to talk to the
sensor for now, I will worry about datalogging down the road.

The Labview help was not clear if I need a timer board also, or just
the card I have.

I hope someone can point me
in a direction to get started!


Here is the sensor datasheet that has the pulse & clock signal
parameters:

Mike;

That DAQ board of yours doesn't have hardware timed digital I/O capabilities, that are required for that aplication of yours.
I suggest you to look into the ones of the 653x family.
