Address length selection for inter-integrated circuit (I2C) communications

A method of operation of a device, the method comprising:

• receiving, via an inter-integrated circuit (I2C) bus, one or more scan acknowledgement messages respectively associated with one or more secondary devices;
• sending, via the I2C bus, one or more address assignment messages to the one or more secondary devices, wherein the one or more address assignment messages respectively include one or more logical addresses that are associated with the one or more secondary devices;
• and
• communicating, via the I2C bus, a data message with at least one secondary device of the one or more secondary devices,
• wherein the data message includes an address field including a logical address of the one or more logical addresses, the logical address indicating that the data message is associated with the at least one secondary device, and
• wherein a length of the address field is based on a quantity of the one or more scan acknowledgement messages.

A non-transitory computer-readable medium storing instructions executable by one or more processors of a device to initiate, control, or perform operations, the operations comprising:

• receiving, via an inter-integrated circuit (I2C) bus, one or more scan acknowledgement messages respectively associated with one or more secondary devices;
• sending, via the I2C bus, one or more address assignment messages to the one or more secondary devices, wherein the one or more address assignment messages respectively include one or more logical addresses that are associated with the one or more secondary devices;
• and
• communicating, via the I2C bus, a data message with at least one secondary device of the one or more secondary devices,
• wherein the data message includes an address field including a logical address of the one or more logical addresses, the logical address indicating that the data message is associated with the at least one secondary device, and
• wherein a length of the address field is based on a quantity of the one or more scan acknowledgement messages.
