Abstract: A method is for updating an original firmware file of an I/O module which communicates with multiple host-end devices and stores the original firmware file. The method includes: receiving a current-received data packet from one host-end device; when it is determined that the current-received data packet is a first data packet constituting an update file, and that the original firmware file is not undergoing an update process, setting a status flag to indicate that the original firmware file is undergoing an update process, storing the current-received data packet; and repeating the previous steps when it is determined that the current-received data packet is not a last one data packet constituting the update file.

Abstract: A method for data communication within an I2C system is provided. The method includes the steps of: a) generating a communication error code indicative of error status when data transmission from a master module to a slave module via an I2C bus fails; b) determining whether to retransmit the data to the slave module according to the communication error code; c) when the determination made in step c) is affirmative, determining whether a number of times of data retransmission(s) associated with the data reaches a predetermined number; d) when the determination made in step c) is affirmative, resetting the master module; and e) recording a communication error event according to the communication error code after step a).
