Hi.

I have the same issue as already asked: #13. For communication the STM32F407G is used. I have the ability to give you the needet data, so we can try to solve the problem together. The Function DumpEE returns 0, so i think the communication is astablished.
After ExtractParameters i have the followind Parameters calculated:

Are the ExtractParameter incorrect?

Hi, as a first step, could you please share the EEPROM dump data.

Some of those values indeed look strange, Based on the EEPROM data you sent, I would say that this is a MLX90641 device that you are using (not MLX90640). Can you please check the marking to make sure what device you have.

P.S. You can log the full data in a csv file and attach it. It would be much easier than series of pictures

Thanks for your support. You are right. I was using the wrong sensor.
