Hi everybody,
I want to read the Temperature of a Texas Instruments TMP275 (http://focus.ti.com/lit/ds/symlink/tmp275.pdf) I2C Sensor with a NI-4851. After some tries i was able to read out the correct temperature:
at the next step i wanted to increase the resolution by sending a 01100000 to the sensor to activate the 12 Bit operation mode, i used a shrinked version of the write example:
but then i get this error:
what do i do wrong?
best regards

Hello,
I do am a beginner and I need to read the TMP275 through the NI8451 with 12bit resolution.
Can you show the VI to configure and read with max resolution?
Thanks
