FIG. 3 is a flowchart of a method for updating stylus settings according to an embodiment of the invention. Please refer to FIG. 3, the method of this embodiment is applicable to the stylus setting update system 10 of FIG. 1. The following is a detailed description of the stylus setting update method of the present invention with various components in the stylus setting update system 10 step.

In step S301, the processing circuit of the host device 110 transmits update data and stability confirmation information through the touch sensing electrodes of the touch panel 111. In step S302, the controller 123 of the stylus pen 120 receives the update data via the signal receiver 122 of the stylus pen 120, and temporarily stores the update data in the storage device 124 of the stylus pen 120. Specifically, the signal receiver 122 can receive radio frequency signals emitted by the touch sensing electrodes of the touch panel 111 to obtain updated data and stability confirmation information. Before actually updating the firmware data, the controller 123 may first temporarily store the updated data in the temporary storage area of the storage device 124 in response to receiving the updated data.

Next, in step S303, the controller 123 of the stylus 120 determines whether the stability confirmation information meets the preset requirements. Step S303 is used to ensure that the stylus 120 can write correct and complete data every time to avoid updating the touch with incorrect or incomplete data. Firmware information of the stylus 120. In addition, the determination of step S303 can be continuously executed during the process of receiving the updated data. For example, the stability confirmation information can be a Cyclic Redundancy Check (CRC) code, and the controller 123 can determine whether the stability confirmation information meets the preset requirements according to the CRC check method to verify the correctness of the updated data .

In one embodiment, the stability confirmation information may include the voltage value received by the signal receiver 122. That is, the controller 123 can determine whether the voltage value is greater than the critical value to determine whether the stability confirmation information meets the preset requirements. The voltage value received by the signal receiver 122 may represent the signal strength sensed by the signal receiver 122. In other words, when the signal strength sensed by the signal receiver 122 is large enough, the correctness of the received data can be ensured. When the signal strength sensed by the signal receiver 122 is too small, it means that the probability of receiving data errors is quite high. Therefore, if the voltage value is greater than the critical value, it means that the stability confirmation information meets the preset requirements. If the voltage value is not greater than the critical value, it means that the stability confirmation information does not meet the preset requirements. In addition, in one embodiment, the controller 123 may further determine whether the voltage value is continuously greater than the threshold value in combination with a time interval (for example, 1 second, etc.), so as to determine whether the stability confirmation information meets a preset requirement.

If the stability confirmation information meets the preset requirements (Yes in step S304), in step S304, the controller 123 uses the updated data to update the firmware data in the storage device 124 of the stylus 120. Specifically, the controller 123 can write the update data recorded in the temporary storage area into a read-only memory or a flash memory in the storage device 124. In one embodiment, when the voltage value received by the signal receiver 122 is greater than the threshold, the controller 123 uses the update data to update the firmware data in the storage device 124.

On the other hand, if the stability confirmation information does not meet the preset requirements (No in step S304), in step S305, the controller 123 returns an update failure message to the host device 110 via the signal transmitter 121 of the stylus 120. The processing circuit of the host device 110 can receive an update failure message via the touch sensing electrode of the touch panel 111.

4 is a flowchart of a method for updating stylus settings according to an embodiment of the invention. Please refer to FIG. 4, the method of this embodiment is applicable to the stylus setting update system 10 of FIG. 1. The following is a detailed description of the stylus setting update method of the present invention with various components in the stylus setting update system 10 step.

In step S401, when the stylus 120 is turned on, the controller 123 enters the first setting mode according to the firmware data in the storage device 124. In step S402, the controller 123 receives a setting update request from the host device 110 via the signal receiver 122 of the stylus pen 120. In one embodiment, via the touch sensing electrodes of the touch panel 111 and the signal receiver 122 of the stylus 120, the processor 113 may send a setting update request to the stylus 120 in response to receiving a user setting operation Controller 123. In addition, the controller 112 can switch the sending and receiving characteristics of some touch sensing channels on the touch panel 111 according to a preset configuration or the current touch position of the stylus 120.

After that, in step S403, the controller 123 can receive the update data from the host device 110 via the signal receiver 122 of the stylus 120. In step S404, the controller 123 can temporarily store the updated data in the storage device 124 of the stylus 120. In step S405, the controller 123 determines whether the stability confirmation information meets a preset requirement.

If the stability confirmation information meets the preset requirements (Yes in step S405), in step S406, the controller 123 writes the updated data into the storage device of the stylus pen 120 Firmware data storage area in 124. And, in step S407, the controller 123 enters the second setting mode according to the updated firmware data.

If the stability confirmation information does not meet the preset requirements (No in step S405), in step S408, the controller 123 returns an update failure message via the signal transmitter 121 of the stylus 120. In step S409, the controller 123 maintains the first setting mode according to the unupdated firmware data. For example, in the first setting mode, the water color of the stylus 120 is black and the strokes are pen strokes. In the second setting mode, the water color of the stylus 120 is red and the stroke is a pencil stroke. Based on this, once the firmware data is updated by the user, the user does not need to perform the pen color setting and stroke setting procedures again every time the stylus 120 is used, so the user can personalize the stylus 120 .

FIG. 5 is a schematic diagram of a scenario for updating stylus settings according to an embodiment of the invention. Referring to FIG. 5, in this embodiment, the touch panel 111 and the display can be integrated into a touch screen S1. The host device 110 can control the touch screen S1 to display a stylus setting menu. The stylus setting menu can be set according to design requirements. As an example, in the application scenario shown in FIG. 5, the stylus setting menu displayed on the touch screen S1 includes stroke setting options, color setting options, and program setting options. The user can use the finger or the stylus 120 to click on the stylus setting menu. It should be noted that, in this embodiment, the user can select the application program. In this way, when the user uses an application, the stylus 120 can be directly set to the corresponding setting state according to the internal firmware data.

After the user selects, the host device 110 can control the touch screen S1 displays an update prompt screen, and the update prompt screen displays a prompt area C1. The prompt area C1 is used to guide the user to place the tip of the stylus 120 at a specific position, so as to facilitate the setting of the transmission and reception characteristics of the touch sensing channel on the touch panel 111. As an example, in the application scenario shown in FIG. 5, the prompt area C1 is a circle to guide the user to place the tip of the stylus 120 in the circle.

After the user places the tip of the stylus 120 in the circle, the stylus 120 and the host device 110 begin to communicate in two-way through the touch panel 111 to update the firmware data in the stylus 120. In this application scenario, the color in the prompt area C1 can be gradually changed to the color selected by the user, as a visual prompt to inform the user whether the firmware data of the stylus 120 is updated. Alternatively, in this application scenario, the host device 110 can also inform the user whether the firmware data of the stylus 120 is updated through display text.

To sum up, in the embodiment of the present invention, the host device and the stylus can communicate in two-way through the touch panel to update the firmware data in the stylus. In this way, when the user wants to change the setting of the stylus, the user does not need to bother to find the stylus control menu from the operating interfaces of various applications. Users only need to perform a one-time setting process to complete personalized settings for the stylus, which greatly improves the convenience of using the stylus. In addition, through the method of verifying the stability confirmation information in the embodiment of the present invention, the security and stability of the firmware can be ensured under the premise of efficiently updating the firmware data.
