Abstract

Disclosed are a firmware update method using single optical port communication and a microcontroller capable of updating firmware. A firmware update method using single optical port communication according to an embodiment of the present invention comprises the steps of: detecting the voltage of a battery when a firmware update start code transmitted from a transmitter has been received to a single optical port performing a data transmission function; transmitting firmware-related information to the transmitter through the single optical port when the detected voltage of the battery is larger than or equal to a predetermined reference voltage; receiving update data corresponding to an update mode determined according to the firmware-related information transmitted from the transmitter and storing the received update data in a predetermined storage area; when the stored update data corresponds to update data in a first mode which can reconstruct a firmware, storing reconstruction information on previous firmware and updating the update data to new firmware; and when the stored update data corresponds to update data in a second mode for updating predetermined data of the previous firmware, updating the predetermined data for the previous firmware to the update data.

Description

technical field [0001] The present invention relates to firmware update, and more particularly to a method for updating firmware using single optical port communication and a microcontroller capable of updating firmware, which method can easily update a microcontroller (MCU) through photo-generated electromotive force using single optical port communication ), said photo-emf is generated in a light-emitting diode (LED) by means of a transport function of light radiated by a transmitter. Background technique [0002] Currently, in general, various wireless communication methods are used to control many electronic devices and devices installed in homes, offices, factories, and the like. Various microcontrollers (MCUs) are used to effectively control these devices and devices. [0003] In order to update the firmware of the MCU, it is necessary to download a new version of the firmware for the update and replace the read only memory (ROM) code of the MCU through one of various...
