Description

Technical Field

[0001] This application relates to the field of mobile terminal technology, specifically to a method and apparatus for upgrading the firmware of a capacitive screen on a mobile terminal. Background Technology

[0002] Traditional methods for upgrading capacitive touchscreen firmware involve erasing the original firmware from memory and directly writing the upgrade firmware into memory. Furthermore, the upgrade firmware cannot be modified during the entire upgrade process. Therefore, when developers improve the functionality and performance of the original firmware, they typically need to include the corresponding mass production information (i.e., factory information) of the capacitive touchscreen in the upgrade firmware to ensure better compatibility. However, due to the numerous tasks of developers and the diversity of capacitive touchscreen types, this method of adding mass production information to the upgrade firmware by developers can easily lead to discrepancies between the mass production information in the upgrade firmware and the actual mass production information of the capacitive touchscreen, resulting in firmware upgrade failure. Summary of the Invention

[0003] The purpose of this application is to provide a method and apparatus for upgrading the firmware of a capacitive screen in a mobile terminal, aiming to solve the technical problem of how to avoid the phenomenon that the mass production information of the capacitive screen in the firmware upgrade program does not correspond to the actual mass production information of the capacitive screen.

[0022] Obtain the upgrade installation package;

[0023] Unzip the upgrade installation package to obtain the driver and the multiple upgrade firmware programs.

[0024] In some technical solutions, the method of obtaining the driver and multiple upgrade firmware programs is through OTA (Over-the-Air Technology).

[0025] In some technical solutions, the mass production information includes mass production time, manufacturer information, and production batch number information.

[0026] In some technical solutions, before the step of erasing the original firmware program of the EEPROM and writing the target upgrade firmware program into the EEPROM, the method for upgrading the capacitive screen firmware of the mobile terminal further includes:

[0027] Obtain the system time of the IC chip;

[0028] Write the system time into the target upgrade firmware program.

Compared with the prior art, this application embodiment uses a driver program to replace manual operation by developers, realizing the accurate addition of mass production information to the corresponding upgrade firmware program.

[0051] The specific implementation methods of the embodiments of this application are described in detail below.

[0052] <Methods for Upgrading the Firmware of Capacitive Screens on Mobile Devices>

[0053] like Figure 1 The image shows a method for upgrading the capacitive touchscreen firmware of a mobile terminal according to an embodiment of this application. Figure 1 The method for upgrading the capacitive touchscreen firmware of the mobile terminal includes:

[0054] S1: Obtain drivers and multiple firmware upgrade programs.

[0055] Step S1 involves the mobile terminal requesting the server to download the data via OTA.

[0056] The mobile terminal can be a portable terminal with communication functions, such as a mobile phone, tablet computer, or PDA.

[0057] S2: Run the driver.

[0058] In this embodiment, the mobile terminal runs the driver program.

[0059] S3: Get the name of the capacitive touchscreen project.

[0060] The capacitive screen project name is the name of the corresponding mobile terminal to which the capacitive screen is applied, for example, such as Xiaomi K40.

[0061] In this embodiment, the driver obtains the capacitive screen project name.

[0062] S4: Search among the multiple upgrade firmware programs for an upgrade firmware program that matches the name of the capacitive screen project to obtain the target upgrade firmware program.

[0063] It should be understood that each of the aforementioned firmware upgrade programs contains a corresponding project name. In this embodiment, the project name of the capacitive screen is compared with the project name of each of the aforementioned firmware upgrade programs. If the two are the same, the corresponding firmware upgrade program is selected as the target firmware upgrade program.

[0064] S5: Set the EEPROM to read / write mode, read the mass production information of the IC chip of the capacitive touchscreen, and write the mass production information into the target upgrade firmware program.

[0065] The mass production information includes mass production time, manufacturer information, and production batch number information.

[0066] S6: Erase the original firmware of the EEPROM and write the target upgrade firmware into the EEPROM.

[0067] In some implementations, such as Figure 2 As shown, after step S6, the method for upgrading the capacitive screen firmware of the mobile terminal further includes:

[0068] S7: Read the program to be verified from the EEPROM, the program to be verified being the upgrade firmware program stored in the EEPROM.

[0069] It should be noted that the upgrade firmware program stored in the EEPROM is the target upgrade firmware program written in step S6.

[0070] S8: Verify the target upgrade firmware program and the program to be verified. If the target upgrade firmware program and the program to be verified are the same, the upgrade is determined to be successful, and the EEPROM is set to normal mode.

[0071] The normal mode is a read-only mode.

[0072] This application embodiment obtains the capacitive screen project name; searches among multiple upgrade firmware programs for an upgrade firmware program matching the capacitive screen project name to obtain the target upgrade firmware program; uses a driver to set the EEPROM to read / write mode, reads the mass production information of the capacitive screen's IC chip, and writes the mass production information into the target upgrade firmware program, thereby ensuring the accuracy of the mass production information writing; then, erases the original firmware program of the EEPROM and writes the target upgrade firmware program into the EEPROM, thereby realizing the firmware upgrade of the mobile terminal's capacitive screen. Compared with the prior art, this application embodiment uses a driver program to replace manual operation by developers, realizing the accurate addition of mass production information to the corresponding upgrade firmware program. Therefore, the method for upgrading the capacitive screen firmware of a mobile terminal provided by this application can effectively avoid the phenomenon that the capacitive screen mass production information in the upgrade firmware program does not correspond to the actual capacitive screen mass production information.

[0073] In some implementations, such as Figure 3 As shown, after step S4, the method for upgrading the capacitive screen firmware of the mobile terminal further includes:

[0074] S11: Get the capacitive touchscreen model.

[0075] The capacitive touchscreen model number is stored in the IC chip. In this embodiment, the driver program obtains the capacitive touchscreen model number from the IC chip.

[0076] The capacitive touchscreen model can be DMT64480T056.

[0077] S12: Detect whether the TP (Touch Plane) model in the target upgrade firmware program is the same as the capacitive screen model. If they are the same, execute S5; if they are different, execute S4.

[0078] In some implementations, such as Figure 4 As shown, prior to step S5, the method for upgrading the capacitive touchscreen firmware of the mobile terminal further includes:

[0079] S21: Obtain the original firmware version number of the original firmware program.

[0080] For example, the original firmware version number may be V1.0.

[0081] S22: Compare the original firmware version number with the target firmware version number of the target upgrade firmware program. If the target firmware version number is greater than the original firmware version number, then execute S5; if the target firmware version number is equal to or less than the original firmware version number, then no upgrade is needed.

[0082] For example, the target firmware version number could be V2.0.

[0083] In other implementations, such as Figure 5 As shown, the method for upgrading the capacitive screen firmware of the mobile terminal can also be implemented according to the following steps:

[0084] 1. After step S3, determine whether the capacitive screen project name exists;

[0085] 2. If the capacitive touchscreen project name exists, then execute steps S4 and S11, and then determine whether the capacitive touchscreen model exists;

[0086] 3. If the capacitive screen model exists, execute S12 and S21, and determine whether the target firmware version number is greater than the original firmware version number. If so, execute S6, and then determine whether the upgrade is successful. If the upgrade is successful, the task is completed (i.e., it ends). If the upgrade is unsuccessful, execute S6 again. If the number of times S6 is executed again exceeds 3, the upgrade operation ends.

[0087] 4. If the capacitive touchscreen model does not exist, or the capacitive touchscreen model is different from the TP model, then write the capacitive touchscreen model into the IC chip, and then execute step S6.

[0088] 5. If the capacitive screen project name does not exist, proceed to step S11, then determine if the capacitive screen model exists. If it exists, proceed to step S6; if it does not exist, write the default capacitive screen model into the IC chip, then proceed to step S6.

[0089] In some implementations, such as Figure 6 As shown, the steps of obtaining the driver and multiple firmware upgrade programs include:

[0090] S31: Obtain the upgrade installation package.

[0091] The upgrade installation package is received by the mobile terminal from the server.

[0092] It should be understood that the upgrade installation package is directly generated by packaging the driver and the multiple upgrade firmware programs, and each upgrade firmware program does not contain an index or other data that occupies physical space.

[0093] This application integrates multiple upgrade firmware programs into a single upgrade installation package, which greatly improves the compatibility and convenience of the upgrade installation package.

[0094] S32: Unzip the upgrade installation package to obtain the driver and the multiple upgrade firmware programs.

[0095] In some embodiments, prior to step S6, the method for upgrading the capacitive touchscreen firmware of the mobile terminal further includes:

[0096] Obtain the system time of the IC chip;

[0097] Write the system time into the target upgrade firmware program.
