实施例一Embodiment one
图1示出了本发明实施例一提供的配件的升级方法的实现流程，详述如下：Figure 1 shows the implementation flow of the accessory upgrade method provided by Embodiment 1 of the present invention, which is described in detail as follows:
在步骤S101中，存储配件的固件至移动终端中。In step S101, the firmware of the accessory is stored in the mobile terminal.
配件通常是通过微控制单元(Micro Controller Unit，MCU)来实现的，MCU的内存一般较小(一般只有2k byte或4k byte)，因此，大部分配件没有无线保真WIFI功能，且没有完善的文件系统，所以，配件不能像移动终端一样通过WIFI下载固件至本地完成升级工作，也不能像存储卡一样，可以实现固件的随意拷贝。Accessories are usually realized by Micro Controller Unit (MCU), and the memory of MCU is generally small (only 2k byte or 4k byte), so most accessories do not have wireless fidelity WIFI function, and there is no perfect file system, therefore, accessories cannot download firmware through WIFI to complete the upgrade locally like a mobile terminal, nor can they copy firmware at will like a memory card.
鉴于配件的上述自身条件限制，在本发明实施例中，先将配件的固件存储至移动终端的存储卡中，然后将移动终端与配件通过USB线或者通过OTG转接头和USB线连接，由移动终端逐次发送固件中的数据至配件中，完成配件的升级。In view of the above-mentioned limitations of the accessory itself, in the embodiment of the present invention, the firmware of the accessory is first stored in the memory card of the mobile terminal, and then the mobile terminal and the accessory are connected through a USB cable or an OTG adapter and a USB cable, and the mobile terminal The terminal sends the data in the firmware to the accessory one by one to complete the upgrade of the accessory.
其中，本发明实施例中提到的存储卡可以包括SD卡、miniSD卡、TF卡、MS卡等。Wherein, the memory card mentioned in the embodiment of the present invention may include SD card, miniSD card, TF card, MS card and the like.
本发明实施例中提到的移动终端包括但不限于手机、平板电脑、手提电脑、音乐播放器(比如MP3)等具有USB接口的电子设备。The mobile terminals mentioned in the embodiments of the present invention include but are not limited to mobile phones, tablet computers, laptop computers, music players (such as MP3) and other electronic devices with USB interfaces.
在步骤S102中，移动终端与配件建立连接。In step S102, the mobile terminal establishes a connection with the accessory.
在本发明实施例中，移动终端和配件之间可以通过两种方式建立连接，一种连接方式如图2所示。In the embodiment of the present invention, there are two ways to establish a connection between the mobile terminal and the accessory, and one connection way is shown in FIG. 2 .
具体的，在图2中，左边示意的终端为移动终端，与移动终端连接的白色的先是OTG转接头，与OTG转接头连接的是USB线，与USB线连接的最右边的终端是配件。Specifically, in FIG. 2, the terminal shown on the left is a mobile terminal, the white one connected to the mobile terminal is an OTG adapter first, the USB cable is connected to the OTG adapter, and the rightmost terminal connected to the USB cable is an accessory.
另一种连接方式是：移动终端直接和配件通过USB线连接。这种情况下，配件是适配器或者移动电源。Another connection method is: the mobile terminal is directly connected to the accessory through a USB cable. In this case, the accessory is an adapter or power bank.
在步骤S103中，移动终端通过OTG转接头以及与所述OTG转接头连接的USB线的D+/D-按照i2c/uart协议发送固件至配件，或者移动终端通过USB线的D+/D-按照i2c/uart协议发送固件至配件。In step S103, the mobile terminal sends the firmware to the accessory through the OTG adapter and the D+/D- of the USB cable connected to the OTG adapter according to the i2c/uart protocol, or the mobile terminal sends the firmware to the accessory through the D+/D- of the USB cable according to the i2c /uart protocol to send firmware to accessories.
在本发明实施例中，移动终端中包括一个转换开关，该转换开关布置在移动终端的USB通信线路上，与移动终端的CPU连接，通过所述转换开关，与移动终端连接的OTG转接头或者与移动终端连接的USB线的D+/D-与所述CPU的i2c/uart连接。In the embodiment of the present invention, the mobile terminal includes a transfer switch, which is arranged on the USB communication line of the mobile terminal and connected to the CPU of the mobile terminal. Through the transfer switch, the OTG adapter connected to the mobile terminal or The D+/D- of the USB cable connected to the mobile terminal is connected with the i2c/uart of the CPU.
具体的，该转换开关的接口如图3所示，包括9个引脚，2个D+、2个D-、1个VDD、1个GND、1个CTRL、一个SCL/UARTTX、1个SDA/UARTRX。Specifically, the interface of the transfer switch is shown in Figure 3, including 9 pins, 2 D+, 2 D-, 1 VDD, 1 GND, 1 CTRL, 1 SCL/UARTTX, 1 SDA/ UART RX.
其中，VCC/GND是电源和地，图中左边的D+/D-可以与OTG转接头或者USB线连接，右边的D+/D-与CPU的D+/D-触点连接，右边的SCL/UARTTX和SDA/UARTRX分别与CPU的一组i2c/uart触点连接，CTRL也与CPU连接，用于在CPU的控制下，将图中左边的D+/D-与图中右边的SCL/UARTTX和SDA/UARTRX连接。Among them, VCC/GND is the power supply and ground. The D+/D- on the left in the figure can be connected to the OTG adapter or USB cable, the D+/D- on the right is connected to the D+/D- contact of the CPU, and the SCL/UARTTX on the right and SDA/UARTRX are respectively connected to a group of i2c/uart contacts of the CPU, and CTRL is also connected to the CPU, which is used to connect D+/D- on the left side of the figure to SCL/UARTTX and SDA on the right side of the figure under the control of the CPU /UARTRX connection.
CTRL为控制信号，CTRL＝1时，图中左边的D+/D-连接到图中右边的D+/D-；CTRL＝0时，图中左边的D+/D-连接到右边的SCL/UARTTX和SDA/UARTRX。这样实现了在不同的需求下，左边的D+/D-与不同的触点连接实现不同的功能。比如，图中左边的D+/D-连接到右边的SCL/UARTTX和SDA/UARTRX，可以通过i2c/uart协议给配件升级固件；图中左边的D+/D-连接到右边的D+/D-时，图中左边的D+/D-连接到CPU的USB功能，不能对配件进行升级。CTRL is the control signal. When CTRL=1, D+/D- on the left in the figure is connected to D+/D- on the right in the figure; when CTRL=0, D+/D- on the left in the figure is connected to SCL/UARTTX and SDA/UART RX. In this way, under different requirements, the D+/D- on the left is connected with different contacts to realize different functions. For example, the D+/D- on the left in the figure is connected to the SCL/UARTTX and SDA/UARTRX on the right, and the firmware of the accessories can be upgraded through the i2c/uart protocol; when the D+/D- on the left in the figure is connected to the D+/D- on the right , the D+/D- on the left in the picture is connected to the USB function of the CPU, and the accessories cannot be upgraded.
所以，在要对配件升级之前，移动终端还需要之前下述步骤：Therefore, before upgrading the accessories, the mobile terminal needs the following steps:
步骤1、接收输入的升级配件指令。Step 1. Receive an input upgrade accessory instruction.
具体的，移动终端的界面上有一个“给配件升级固件”的图标，用户点击该图标后，CPU即可接收到一个升级配件指令。Specifically, there is an icon of "upgrade firmware for accessories" on the interface of the mobile terminal. After the user clicks on the icon, the CPU can receive an instruction to upgrade accessories.
步骤2、移动终端根据所述升级配件指令控制所述转换开关，通过所述转换开关，控制与所述移动终端连接的OTG转接头或者与所述移动终端连接的USB线的D+/D-与所述CPU的i2c/uart连接。Step 2. The mobile terminal controls the transfer switch according to the upgrade accessory instruction, and through the transfer switch, controls the D+/D- and i2c/uart connection to the CPU.
具体的，CPU接收到升级配件的指令后，即可通过控制信号CTRL＝0控制转换开关，使图3中左边的D+/D-连接到右边的SCL/UARTTX和SDA/UARTRX。Specifically, after the CPU receives an instruction to upgrade accessories, it can control the transfer switch through the control signal CTRL=0, so that D+/D- on the left in Figure 3 is connected to SCL/UARTTX and SDA/UARTRX on the right.
另外，在对配件升级之前，还要先使配件进入固件升级模式。其中，配件可以通过特定的方式，比如瞬间短路、按下预定的某几个组合按键等方式进入固件升级模式。In addition, before upgrading the accessories, the accessories must first enter the firmware upgrade mode. Among them, the accessory can enter the firmware upgrade mode through a specific method, such as an instant short circuit, pressing a predetermined combination of keys, and the like.
在使配件进行固件升级模式后，移动终端与配件建立连接，并且移动终端接收到用户输入的给配件升级固件的指令后，即可通过下述的步骤完成配件的升级，具体步骤如图4所示，包括：After the accessory is in the firmware upgrade mode, the mobile terminal establishes a connection with the accessory, and after the mobile terminal receives the instruction to upgrade the firmware of the accessory input by the user, it can complete the upgrade of the accessory through the following steps, as shown in Figure 4. display, including:
步骤1、移动终端发送擦除命令至配件，通知配件擦除ROM空间的数据。Step 1. The mobile terminal sends an erase command to the accessory to notify the accessory to erase the data in the ROM space.
具体的，移动终端发送ERASE命令至配件，通知配件擦除ROM空间的数据。配件接收到ERASE命令后，将其ROM空间的数据全部擦除。Specifically, the mobile terminal sends an ERASE command to the accessory to notify the accessory to erase data in the ROM space. After the accessory receives the ERASE command, all data in its ROM space will be erased.
步骤2、移动终端发送固件写入请求命令至配件，通知配件等待接收写入地址。Step 2. The mobile terminal sends a firmware write request command to the accessory, and notifies the accessory to wait for receiving the write address.
具体的，移动终端发送WRITE_CMD命令至配件，通知配件等待接收写入地址。配件接收到WRITE_CMD命令，等待写入地址的到来。Specifically, the mobile terminal sends a WRITE_CMD command to the accessory, notifying the accessory to wait for receiving the write address. The accessory receives the WRITE_CMD command and waits for the write address to arrive.
步骤3、移动终端发送写入地址至配件，通知配件等待接收固件。Step 3. The mobile terminal sends the write address to the accessory, and notifies the accessory to wait to receive the firmware.
具体的，移动终端发送WRITE_ADDR至配件，通知配件等待接收移动终端发送的固件。配件接收到WRITE_ADDR后，等待固件中的数据的到来。Specifically, the mobile terminal sends WRITE_ADDR to the accessory, notifying the accessory to wait to receive the firmware sent by the mobile terminal. After the accessory receives the WRITE_ADDR, it waits for the arrival of the data in the firmware.
步骤4、移动终端按照i2c/uart协议发送固件中的N个字节的数据至配件，以由配件将所述N个字节的数据存入ROM空间的相应地址中。Step 4. The mobile terminal sends N bytes of data in the firmware to the accessory according to the i2c/uart protocol, so that the accessory stores the N bytes of data in a corresponding address in the ROM space.
具体的，移动终端按照i2c/uart协议发送固件中的N个字节的数据至配件，配件将这N个字节的数据存入ROM空间，具体存入的地址为ROM空间的(WRITE_ADDR～WRITE_ADDR+N-1)。Specifically, the mobile terminal sends N bytes of data in the firmware to the accessory according to the i2c/uart protocol, and the accessory stores the N bytes of data in the ROM space, and the specific storage address is (WRITE_ADDR～WRITE_ADDR +N-1).
步骤5、返回步骤3，直至固件中的数据全部发送完毕。Step 5, return to step 3 until all the data in the firmware is sent.
