The user has two choices to load an EEPROM configuration in a MLX90614 module:
● Upload
● Quick upload
power supply before writing the EEPROM memory of the module. This process takes some
time. This option is useful when the user wants to configure MLX90614 modules of
different versions. It is recommended to use this option as it provides additional safety (a
3V module would not be subjected to overvoltage stress unintentionally).
configuration the Quick upload option might be preferred. In this case the user must initially
choose the module voltage supply manually in the field below the button Quick upload
(See Fig. 5.18 or Fig. 5.19) and push the button Quick upload. In this case the software
does not make module power supply verification so the time of module configuration is
reduced. Tick SMBus increment field if you want the SMBus address field to be
incremented automatically.
indeed this is not necessary because the software automatically uses address 0x00 which
is universal address for all MLX90614 devices. The users must realize also that when
using the “Configuration uploader” window only one MLX90614 device should be present
or all devices in the network are changed. If you work in a network and want to change the
configuration of a specific module in the network use”Configuration utility” window (see 5.3
Configuration of MLX90614 modules).
