EEPROM version register documentation mismatch with library ?

[linkineo]

We're using both Medical/Extended-grade and standard versions of the sensor.

In the library during initialization, the following check is performed in the EEPROM version register 0x240b

mlx90632-library/src/mlx90632.c

Line 467 in 0b1be08

if ((eeprom_version & 0x7F00) == MLX90632_XTD_RNG_KEY)

with

mlx90632-library/inc/mlx90632.h

Line 192 in 0b1be08

#define MLX90632_XTD_RNG_KEY 0x0500 /**Extended range support indication key */

Yet the latest datasheet from your website does not document this register. It however documents the product code like this:

Questions:
Is the magic 0x0500 always reflecting a medical-grade device or which meaning does it have ? Why not use in the library the product code as a way to identify a medical-grade device ?

[Letme]

0x0500 does not mention anything about medical-grade device, so I am not sure why you would think this is connected?

The extended range is read at initialization (

mlx90632-library/src/mlx90632.c

Line 446 in 0b1be08

ret = mlx90632_i2c_read(MLX90632_EE_VERSION, &eeprom_version);

) from EE_VERSION (https://github.com/melexis/mlx90632-library/blob/master/inc/mlx90632.h#L87) which is on address 0x240B and it defines the eeprom content variation which enables us to keep some backwards compatibility with older versions as well as with newer extended range versions. The product code you are referencing is not present in older devices.
