Hello,
On the Labjack homepage I found the example for the sensor MLX90614 with the UE9. I connected everything with the T7 Pro (SCL FIO0, SDA FIO1) and used the LabView Vi "I2C EEPROM Read" to get some Data.
When i start to read out the Sensor, all Data i get is FF.
I thought that the Sensor is not running correctly, but when i use a Arduino to get some data, it works fine.
Maybe someone can help me with my Problem. I think i´ve set something wrong but i just don´t see my mistake.
Thank you very much for your help

Hello,
From the screen shot that you sent over, it looks like there may be a few things going on. First and foremost, it looks like you aren't getting any received ACK bits. There are some helpful pointers in the I2C FAQ/Common Questions section in our I2C App Note (scroll to the bottom of the page). Additionally, have you gone through our MLX90614 app-note?
You likely have the pull-up resistors installed if you are getting data using an Arduino, however the following comments apply:
1. I suggest switching to an EIO/CIO/MIO line if that is an option.
2. Double check the slave address you are using. The UD library requires a using a 7-bit slave address that is shifted over by 1 bit. You should use the slave address 180 instead of 90.
Hopefully this gets you going in the right direction.
