Float division zero error for MLX90641 with RasPi3

Hi Seeed Studio Team,

Thank you for your support.

I am testing 101020992 with connecting to Raspberry Pi 3.
The connection image is as follows.

mlx90641.drawio

I connected it to a Raspberry Pi and ran Getting Started by Raspberry Pi, which is

published by seeed studio, to check its operation.
When I entered the command 「sudo ircamera I2C MLX90641」and ran the Python code, I got a error「float division by zero」

Investigating the cause, we found that 0x2427[kVdd] is 0. Is this the cause?

If this is the cause,
Can you give some advice for why this happened and what should we do for it?

Hi there,
Just wanting to know Have you performed all of the steps on the WIKI? And What do you get when you do the Basic readings test py ?
90641-raspi1
Can you say what pins your connected to on the PI?

Yes Performed all.

And What do you get when you do the Basic readings test py ?

Same as ZeroDivisionsError when Basic readings test py was performed.

Can you say what pins your connected to on the PI?

connected to GPIO2,GPIO3. Here is the Pic.

Hi there,
Very Good.
So because you get error on basic py test, No need to torture yourself with the other code examples.
It looks like address is correct. However it either getting the wrong responce or NULL ?
Can you change the pins and edit the code , which BTW can you post? or is it the Wiki example if so then it’s not necessary.
