[0003] However, in actual applications, software upgrades for DALI devices still face problems such as complex operations and low upgrade efficiency. The IEC62386-105 firmware update standard defines a 32-bit transmission frame to transmit the firmware binary image to the DALI device in the form of blocks to achieve online firmware updates for DALI devices.

DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0023] In order to solve the problem of low software upgrade efficiency using DALI devices in the related art, the embodiment of the present application provides a software upgrade method based on the DALI interface, such as Figure 1 The flowchart of the software upgrade method based on the DALI interface provided in this embodiment is as follows: Step 110, configuring the UART transceiver mode in the transceiver pins of the DALI interface; Step 120: When receiving an upgrade instruction from the host computer, trigger the UART transceiver mode according to the upgrade instruction; Step 130: Perform IAP upgrade on the target software according to the UART transceiver mode.

[0024] Specifically, in this embodiment, UART (Universal Asynchronous Receiver / Transmitter) is a commonly used serial communication protocol, which is widely used in data communication between computers, microcontrollers (MCUs), sensors and various other electronic devices. To implement DALI (Digital Addressable Lighting Interface) transceiver pin multiplexing as UART (Universal Asynchronous Receiver Transmitter) function on microcontroller (MCU), first, you need to ensure that the selected MCU supports pin multiplexing function, that is, the same physical pin can be configured as different functions (such as DALI or UART) as needed. According to the pin configuration of MCU, the pin originally used for DALI communication is connected to MCU through appropriate circuits. Then, in the main loop or interrupt service routine of DALI communication, write code to detect whether the data received from the DALI network contains upgrade instructions. When the upgrade instruction is detected, disable the DALI transceiver mode (such as general I / O mode) of the DALI interface, and enable the UART transceiver mode, and prepare to receive upgrade data. Switch the main loop or interrupt service routine of the system to start processing UART communication instead of DALI communication, use the UART interface to receive upgrade data (such as firmware image), verify the received data, and if the data is valid, perform the software IAP (In-Application Programming) upgrade process. After the upgrade is completed, the system needs to be restored to DALI mode to continue normal operation. It can be understood that when the baud rate of UART is set to 9600bps, and the communication rate of DALI is 1200bps, the software IAP upgrade is performed through the UART transceiver mode, and the software upgrade can be performed without disassembling the DALI device, thereby improving the upgrade efficiency and communication efficiency.

[0025] In an optional implementation of the present embodiment, the step of configuring the UART transceiver mode in the transceiver pin of the DALI interface includes: determining a target transceiver pin that supports the UART transceiver mode in the DALI interface; initializing the target transceiver pin according to preset configuration information; switching the mode of the target transceiver pin through a preset test instruction; if the target transceiver pin can be switched to the UART transceiver mode, determining that the configuration of the UART transceiver mode is completed.

[0026] Specifically, in this embodiment, it can be understood that different pins in the DALI interface have different functions. Most of the transceiver pins have only general I / O mode, while some of the transceiver pins can support UART communication. These pins are usually marked as TX (transmit) and RX (receive). In the firmware of the MCU, the selected pins are configured to the UART mode by programming, for example, setting the function selection register of the pin (such as GPIO (General Purpose Input Output, general input and output) multiplexing function register) to switch the pin from general I / O mode to UART function. After switching, you also need to configure the parameters of the UART module, such as baud rate, data bit, stop bit and check bit. After the UART transceiver mode is configured, in the non-upgraded case, the target transceiver pin of the DALI interface is still in I / O mode. At this time, the target transceiver pin can be tested to detect whether the I / O mode of the target transceiver pin can be switched to UART transceiver mode through the preset test command (such as the upgrade command sent by the host computer). If the target transceiver pin can be switched to UART transceiver mode, it is determined that the configuration of the UART transceiver mode is completed. If the target transceiver pin fails to switch to UART transceiver mode successfully, it is necessary to recheck the pin configuration or UART parameter settings.

[0027] In an optional implementation of the present embodiment, the step of performing IAP upgrade on the target software according to the UART transceiver mode includes: detecting whether the DALI interface receives the upgrade file; when the upgrade file is detected, controlling the transceiver pins to perform local upgrade; when the upgrade file is not detected, controlling the transceiver pins to perform serial port upgrade.

[0028] Specifically, in this embodiment, after the MCU is powered on, the DALI interface needs to be able to detect whether the upgrade file has been received, and decide whether to perform local upgrade or serial port upgrade based on the detection result. Local upgrade refers to reading the upgrade file from the storage medium inside the device (such as Flash, SD card, etc.) and performing firmware upgrade. Serial port upgrade receives the upgrade file from the external device (such as the host computer) through the serial port (such as UART) and writes it to the storage medium of the device to complete the firmware upgrade. In the process of detecting whether the upgrade file has been received, it can be determined whether the upgrade file has been received by checking the specific directory or file mark on the internal storage medium, or by monitoring the serial port to detect whether the instruction to start transmitting the upgrade file has been received. When the upgrade file is detected, the transceiver pin is controlled to perform local upgrade, and when the upgrade file is not detected, the transceiver pin is controlled to perform serial port upgrade. Once the upgrade file is detected, the device needs to control the UART transceiver pin to perform corresponding operations according to the source of the upgrade file (internal or external). It should be noted that the UART transceiver pin itself does not directly control the upgrade process, but serves as a channel for data transmission to speed up the efficiency of firmware upgrade.

[0029] In an optional implementation of this embodiment, when an upgrade file is detected, the step of controlling the transceiver pins to perform a local upgrade includes: obtaining the upgrade file from the backup area of ​​the DALI interface; copying the upgrade file to the application software area corresponding to the target software; and clearing the corresponding upgrade flag in the backup area after the upgrade file is copied.

[0030] Specifically, in this embodiment, during the firmware upgrade process, it is first necessary to identify and access the backup area of ​​the storage medium, where the upgrade file is stored. The upgrade file is located by reading a specific address of the area or searching for a specific file identifier. After obtaining the upgrade file, the upgrade file is copied to its target location, that is, the application software area corresponding to the target software. During the copying process, data verification is performed, such as using algorithms such as CRC, MD5 or SHA to verify data consistency. In order to ensure that the upgrade operation will not be repeated after the MCU is powered on, the corresponding upgrade flag in the backup area is cleared after the upgrade file is copied, and the file system or storage structure of the backup area is accessed to find the flag or mark associated with the upgrade file, and the flag is cleared or reset.

[0031] In an optional implementation of the present embodiment, when the upgrade file is not detected, the step of controlling the transceiver pins to perform a serial port upgrade includes: receiving the upgrade file sent by the host computer through a preset communication protocol; burning the upgrade file to the target software, and detecting the integrity of the upgrade file; when the upgrade file is a complete file, determining that the serial port upgrade is completed.

[0032] Specifically, in this embodiment, when the host computer does not send the upgrade file, a connection can be established with the host computer through the UART serial communication protocol, and wait to receive the upgrade file sent by the host computer. When the data sent by the host computer is received, it is parsed according to the provisions of the communication protocol, and the data packet of the upgrade file is extracted. After receiving the complete upgrade file, this file is burned (written) to the target software area. After the burning is completed, the device needs to verify the integrity of the upgrade file to ensure that the file is not damaged during the transmission and burning process. The verification method includes but is not limited to using a checksum, CRC (cyclic redundancy check) or other algorithm to verify the integrity of the upgrade file. If the integrity verification of the upgrade file passes, that is, the file is complete and not damaged, it is determined that the serial port upgrade is completed.

[0033] In an optional implementation of the present embodiment, after the step of performing IAP upgrade on the target software according to the UART transceiver mode, it also includes: if the target software upgrade fails, the DALI interface triggers a recovery mechanism; obtains a backup file of the target software from the backup area according to the recovery mechanism; and loads the target software according to the backup file.

[0034] Specifically, in this embodiment, during the upgrade process, the MCU will monitor the status and results of the upgrade. If an upgrade failure is detected (for example, the upgrade file is incomplete, the checksum does not match, the burning process is interrupted, etc.), the MCU will trigger the recovery mechanism, that is, the MCU will check the upgrade status regularly or according to specific events (such as data reception completion, burning completion, etc.) during the upgrade process. If any condition indicating that the upgrade has failed is detected, the MCU will stop the current upgrade process and prepare to enter the recovery mode, such as by modifying the internal register, setting the status flag or sending a specific signal to trigger the recovery mechanism. Once the recovery mechanism is triggered, the MCU will access the backup area of ​​the device, obtain the backup file of the target software from it, and verify the integrity and validity of the backup file. If the backup file is valid, the MCU will read it into the internal memory or cache, prepare to load it, and write the data of the backup file to the storage area of ​​the target software. During the writing process, the MCU may need to perform additional verification to ensure that the data is written correctly and is not damaged. After the writing is completed, the internal state is reset, the software version information is updated, or the self-test program is executed, so that the system enters a new running state to load and run the restored target software.

[0035] Based on the embodiment scheme of the above application, a UART transceiver mode is configured in the transceiver pin of the DALI interface; when receiving an upgrade instruction from the host computer, the UART transceiver mode is triggered according to the upgrade instruction; and the target software is upgraded by IAP according to the UART transceiver mode. Through the implementation of the scheme of this application, when the DALI interface receives an upgrade instruction from the host computer, the UART transceiver mode is triggered according to the upgrade instruction, and the software can be upgraded without disassembling the DALI device, thereby improving the upgrade efficiency and communication efficiency.
