I have no idea what the problem could be, any suggestions ?

It seems that you only read subpage 1 of data. In chess mode, two pages of data should be merged into one page of data. You can refer to page 15 of the datasheet. Which fream rate did you set?And the I2C clock frequency is?

thanks for the response.

I for the evaluation I just copied your main code.Yes I am i chess mode, I changed frame rate to 4Hz and I believe I2C clock is 100khz. should I go for 400khz ?

Okay I solved it

Turns out you have to do: int status = MLX90640_GetFrameData(MLX90640_address, mlx90640Frame); 2 times before getting Vdd or doing calculations

cheers
