[0022] The present invention will be described below using multiple embodiments. Please note that the components in each embodiment may be implemented via hardware (e.g., a device or circuit) or firmware (e.g., at least one program written into a microprocessor). Furthermore, the terms "first," "second," and similar terms in the following description are used solely to define different components, parameters, data, signals, or steps. They are not intended to limit their order. For example, the first device and the second device may have the same structure but be different devices.

[0023] Furthermore, in the following embodiments, an optical mouse is used as an example to illustrate the concept of the present invention. However, the debug mode triggering method disclosed in the present invention can be applied to any other electronic device (eg, an optical navigation device).

[0024] Figure 1 FIG. 1 is a schematic diagram of an optical mouse according to an embodiment of the present invention. Figure 1 As shown, the optical mouse 100 includes a plurality of buttons B1, B2, B3, B4, B5 and a processing circuit 101. Please note that the optical mouse 100 is not limited to including five buttons B1-B5. The number and / or arrangement of the buttons of the optical mouse 100 may vary. Figure 1 The example shown in FIG. Buttons B1-B5 correspond to one of the first button layout and the second button layout, indicating that buttons B1-B5 correspond to one of the available button layouts. Furthermore, processing circuit 101 is configured to control optical mouse 100 to enter debug mode when at least two of buttons B1-B5 are pressed to achieve a predetermined button combination. For example, pressing buttons B1, B2, and B5, or pressing buttons B3, B4, and B5. The predetermined button combination may include more than one combination. For example, pressing buttons B1, B2, and then pressing buttons B3, B4.

[0025] The optical mouse 100 may further include an image sensor, and the processing circuit 101 determines the position of the optical mouse according to an image sensed by the image sensor.

[0026] The debug mode may be a mode for testing the optical mouse 100 to determine if it has errors, or a mode for calibrating parameters of the optical mouse 100 to improve its performance. In one embodiment, the debug mode allows the optical mouse 100 to allow its firmware or stored programs to be modified, or to allow new programs or firmware to be written to it.

[0027] In one embodiment, after a predetermined key combination is reached, processing circuit 101 controls optical mouse 100 to perform a first test corresponding to the first key layout or a second test corresponding to the second key layout to detect whether optical mouse 100 corresponds to the first or second key layout. In short, after a predetermined key combination is reached, optical mouse 100 determines whether it has the first or second key layout, thereby enabling more accurate calibration of optical mouse 100 in debug mode.

[0028] In one embodiment, after at least two buttons are pressed to achieve a predetermined button combination, the processing circuit 101 controls the optical mouse 100 to perform a first test. If the result of the first test indicates that the button does not have the first button layout, the processing circuit 101 controls the optical mouse 100 to perform a second test.

[0029] In another embodiment, after at least two buttons are pressed to reach a predetermined button combination, the processing circuit 101 controls the optical mouse 100 to perform a first test. Then, if the result of the first test indicates that the buttons have the first button layout, the processing circuit 101 controls the optical mouse 100 to perform the first test but does not control the optical mouse 100 to perform the second test.

[0030] In another embodiment, the processing circuit 101 controls the optical mouse 100 to perform the first test and the second test simultaneously after at least two buttons are pressed to reach a predetermined button combination.

[0031] The first and second tests can be performed by detecting the voltages of certain components or endpoints within the optical mouse 100, or by sending signals to detect output signals from certain endpoints. In this way, the type of the key layout can be detected. It should be noted that the steps for testing the key layout are not limited to the above examples.

[0032] In one embodiment, the aforementioned button layout refers to the circuitry connected between the internal circuitry or IC (Integrated Circuit) of the optical mouse 100 and the buttons B1, B2, B3, B4, and B5 on the optical mouse 100. Through this circuitry, when any of the buttons B1, B2, B3, B4, and B5 is pressed, the internal circuitry or IC of the optical mouse 100 can generate a corresponding signal to control the optical mouse 100.

[0033] The button layout of the optical mouse 100 can have various structures. Figure 2 as well as Figure 3 Two examples of key layouts according to embodiments of the present invention are shown. Figure 2 As shown, the key layout (reference numeral 200), which may be referred to as "KeyScan," includes multiple switches Ba, Bb, Bc, Bd, Be, Bf, Bg, Bh, Bi, Bj, Bk, and Bl, multiple terminals T1, T2, and T3, and read points R0, R1, R2, and R3. Each switch Ba, Bb, Bc, Bd, Be, Bf, Bg, Bh, Bi, Bj, Bk, and Bl corresponds to a key of the optical mouse 100. Furthermore, scan signals are alternately provided to terminals T1, T2, and T3. If a key is pressed, the corresponding switch turns on. Therefore, the scan signal can be used to determine which key was pressed.

[0034] Figure 3The key layout 300 in the optical mouse 100 may be referred to as a "GPIO layout" and uses the pins of the IC inside the optical mouse 100. GPIO stands for general-purpose input / output. Figure 3 As shown, the button layout 300 includes switches Ba, Bb, Bc, Bd, Be, Bf, Bg and resistors Ra, Rb, Rc, Rd, Re, Rf, Rg. Each switch Ba, Bb, Bc, Bd, Be, Bf, Bg corresponds to a button of the optical mouse 100 and is coupled between one of the resistors Ra, Rb, Rc, Rd, Re, Rf, Rg and one of the pins Pa, Pb, Pc, Pd, Pe, Pf, Pg. The pins Pa, Pb, Pc, Pd, Pe, Pf, Pg are pins of the IC inside the optical mouse 100. The IC mentioned here can be responsible for various functions. For example, the IC can be the processing circuit 101 or the image sensor of the optical mouse 100, but it can also be an IC responsible for other functions. In addition, in one embodiment, the resistors Ra, Rb, Rc, Rd, Re, Rf, Rg are used to form impedance matching, but are not limited to this. By Figure 3 The structure shown can inform the IC having pins Pa, Pb, Pc, Pd, Pe, Pf, and Pg whether any button is pressed, so as to generate a control signal to control the optical mouse 100.

[0035] In the aforementioned embodiment, when a predetermined key combination is reached (at least two keys are pressed to reach the predetermined key combination), the debug mode is triggered. However, triggering the debug mode may further include other steps. Figure 4 as well as Figure 5 A schematic diagram illustrating how to trigger the debugging mode of an optical mouse according to an embodiment of the present invention is shown. Figure 4 In the embodiment of FIG, when a predetermined key combination is reached and the optical mouse 100 is in the lift mode, the processing circuit 101 controls the optical mouse 100 to enter the debug mode. If the optical mouse 100 is in the lift mode, it means that the bottom of the optical mouse 100 is more than a predetermined distance away from the surface Sr, such as Figure 4 On the contrary, if the optical mouse 100 is not in the lifting mode, it means that the bottom of the optical mouse 100 contacts the surface Sr, as shown in FIG. Figure 4 As shown in the figure below, the surface Sr can be any surface. For example, the surface Sr can be a table or a mouse pad. The predetermined distance can be set to any desired value.

[0036] exist Figure 5In this embodiment, when a predetermined key combination is reached and the movement of the optical mouse 100 within a predetermined time interval conforms to a predetermined trajectory, the processing circuit 101 controls the optical mouse 100 to enter a debug mode. For example, when a predetermined key combination is reached and the movement of the optical mouse 100 within a predetermined time interval conforms to the shape of a horizontal 8, the optical mouse 100 enters debug mode. Please note that the trajectory here can be replaced with any other trajectory, and is not limited to a horizontal 8.

[0037] In another embodiment, the processing circuit 101 controls the optical mouse 100 to enter a debug mode when a predetermined key combination is reached within a predetermined time interval after the optical mouse 100 receives power (is powered on). For example, the optical mouse 100 is connected to a computer and receives power when the computer is turned on. In this case, the optical mouse 100 enters the debug mode when a predetermined key combination is reached within a predetermined time interval after the computer is turned on. For another example, "receiving power" may mean that at least one powered battery is installed in the optical mouse 100.

[0038] The predetermined time interval can be set to any desired value. In one embodiment, the predetermined time interval is set to 21 seconds, so that the user has sufficient time to control the optical mouse 100 to enter the debug mode. In another embodiment, when the optical mouse 100 receives power, if a predetermined key combination is achieved, the optical mouse 100 enters the debug mode. In other words, if a key on the optical mouse 100 is pressed to achieve the predetermined key combination before the optical mouse 100 receives power, the optical mouse 100 will enter the debug mode after receiving power.

[0039] In short, in the above embodiment, the optical mouse 100 enters debug mode when certain conditions are met, and does not enter debug mode when certain conditions are not met. Specific conditions may include: a predetermined key combination, a predetermined key combination and a lift mode, a predetermined key combination and a predetermined trajectory, or a predetermined key combination and receiving power.

[0040] According to the aforementioned embodiments, a debug mode triggering method can be obtained. Figure 6 A flowchart of a debug triggering method according to an embodiment of the present invention is shown, which is applicable to an electronic device including a plurality of buttons, wherein the layout of the buttons corresponds to one of a first button layout and a second button layout. Figure 6 The methods in include:
