[0069] Figure 4 : is a flow chart of a method for fast tuning an encoder provided in an embodiment of the present application. The method is used in the mobile radio receiving device described in the above embodiments. The method includes:

[0070] S1, the central processing module receives the response interrupt generated by the encoder module and determines the operation item of the current menu bar / submenu bar;

[0071] The current menu bar / sub-menu bar refers to the menu interface currently displayed on the screen, such as the FM interface or the song playback interface. The menu bar and sub-menu bar are determined to determine the pre-adjustment range. The more content under the menu bar and sub-menu bar, the larger the pre-adjustment range.

[0072] S2. Determine the pre-adjustment range of the encoder module operation according to the operation item, and calculate and determine the rotation direction and rotation time of the encoder module according to the level signal value input by the encoder module;

[0073] The operation items represent the specific options under the menu bar and submenu bar content. For example, the song list submenu bar contains a total of 800 songs in the memory, which is equivalent to the encoder adjustment range of [1,800]. Correspondingly, if it is a function menu bar, such as including volume, brightness, language, and personalization, then the adjustment range is equivalent to [1,4].

[0074] The encoder module and the housing knob are connected as one piece, so the left and right directions can represent the increase and decrease of the pre-adjustment range, and the rotation time does not represent the event from the start of the rotation to the selection of the target, but the time maintained by a rotation (interrupted by the hardware, the encoder generates a step value change). Note that if the pre-adjustment range is large, it needs to be adjusted manually multiple times, which is manifested as a half-turn or several turns. The encoder step value (such as the encoder minimum scale value) changes gradually, which is essentially the time of each step value change. There may be artificial pause time, and the maintenance time of the pause is not included, but the calculation starts again.

[0075] S3. Calculate the cumulative result increment according to the rotation time and the rotation direction, locate the target output value according to the pre-adjustment range, and adjust the parameters according to the target output value.

[0076] The cumulative result increment is the increase in the effective timing time from the start of rotation to the present after each encoder step value changes. This step takes into account the continuous rotation accumulation in a large range, because the rotation also has acceleration, uniform speed and deceleration adjustment processes. At this time, the cumulative result increment can represent the acceleration, uniform speed or reduction of the screening speed. For example, if the value is in the range of [1-9000], then it is necessary to determine the rotation adjustment rate when rotating quickly to quickly filter the target. To achieve this function, the filtering range represented by the encoder step value can be changed according to the adjustment range and the knob speed. When the speed is slow, one encoder step value represents one screening target (for example, one song is selected at a time, one by one according to the number), and when the knob speed is fast, one encoder step value represents 5 or 10 screening targets. This range is equivalent to the acceleration value, which changes dynamically according to the adjustment range and the rotation speed. From the perspective of human habit, when the target song is not selected, the number of rotations can be reduced by rotating quickly, and the speed can be reduced when approaching the target song, so that one can select one by one until the target is selected.

[0077] The central processing module can specifically identify the encoded data by referring to the following process:

[0078] The encoder module's knob encoder is set to dual-channel encoding, namely A channel and B channel. The level signals generated by each channel in two adjacent interrupt tasks are Aold level and Anew level, Bold level and Bnew level. In this way, the central processing module only needs to record the new and old data of the two interrupt dual channels to determine the rotation direction and rotation time. The specific judgment process is as follows:

[0079] When Aold is low, Anew is high, Bold is high, and Bnew is low, the knob encoder is determined to rotate clockwise and the corresponding encoding step value S;

[0080] When Aold is high, Anew is low, Bold is low, and Bnew is high, the knob encoder is determined to rotate counterclockwise and the corresponding encoding step value S;

[0081] If none of the above conditions are met, it is determined that the knob encoder has not rotated. Optionally, use a value to save the current rotation direction C. Each time a hardware interrupt of channel A and channel B is generated, it means that the encoder rotates a step value, and the count value S will be accumulated by 1.

[0082] When a hardware interrupt occurs, the timer count is triggered inside the central processing module to record the current time Ta. The next time the encoder knob is continuously rotated, an interrupt (timing Tb) is generated. The time interval T between the two times is determined based on the interrupt count generated by the continuous adjustment of the knob encoder, and is determined as the rotation time.

[0083] In some embodiments, the cumulative result increment is calculated according to the rotation time and the rotation direction, and the target output value is located according to the pre-adjustment range, and the parameter adjustment is performed according to the target output value, including:

[0084] When the time interval T is less than the maximum threshold K, greater than the minimum threshold Kn, and the direction is the same as the previous rotation, it indicates fast or slow rotation; the step value S is cumulatively updated according to the acceleration coefficient F and the time interval T to obtain the cumulative result increment Fs, which is calculated as follows:

[0085]

[0086] When the time interval T is less than the minimum threshold Kn and the direction of rotation is the same as the previous rotation, it indicates slow and uniform rotation. The cumulative result increment Fs is expressed as follows:

[0087] F s =F n +S

[0088] F nIndicates the minimum fixed time interval; from this, it can be seen that when the user rotates the knob at a normal uniform speed, the output value will accumulate the uniform output value Fs in a single step each time. When the user rotates the knob quickly, the output value will accelerate the accumulation of the output value Fs according to the decrease in the time interval between the two interruptions, thereby achieving the purpose of quickly positioning the output value with a single knob.

[0089] According to the correspondence between the count value represented by the cumulative result increment Fs and the value of the pre-adjustment range, the selected target output value is determined and the parameters are adjusted; the parameters are the function options, volume, frequency, and band of the menu bar or submenu bar.

[0090] In particular, the maximum threshold K and the minimum threshold Kn are fixed values, and the best values ​​will be obtained based on the actual test encoder selection and operation experience. The acceleration coefficient will be appropriately set according to the user's numerical operation range. If the range is too large, a fixed large value will be taken, and if it is too small, a fixed small value will be taken. This value can also be customized by the user.

[0091] In particular, this method allows the operator to quickly locate the required menu or frequency value. When there are too many menus in the user interface, the user only needs to slightly and quickly rotate the encoder knob, and the user interface can selectively jump to the required menu item at the back. For example, if the user slowly rotates the knob according to the above method and the appropriate threshold, the increment will be less than 1, rounded to 1, and the final rotation value will be output in sequence as 1, 2, 3, 4, 5, 6... If the user accelerates the rotation of the knob according to the above method and the appropriate threshold, the increment will be less than 1, and the final rotation value will output a variable value such as: 1, 3, 6, 12, 18... as the user rotates the knob faster.

[0092] In particular, when encountering a very large numerical range, in order to more accurately and quickly locate the precise value within the range through the knob encoder, the number of digits of the numerical value is divided and adjusted through the program of the button encoder. For example, if the value is a 7-digit long integer, when pressing once, the first three digits of the value can be quickly adjusted through the above method. When pressing a second time, the last four digits of the value can be quickly adjusted through the above method. Pressing the button again can exit the split mode adjustment. Based on the above method, when the user uses the encoder knob to select the corresponding function, the central processing module will quickly locate the menu item required by the user.

[0093] Based on the above method, when the user uses the encoder knob to tune the receiving frequency in the following full-band radio and full-band receiver functions, the central processing module will quickly locate the required frequency according to the speed at which the user rotates the knob. If the current frequency is far away from the user's target frequency, the user only needs to quickly rotate the knob to modify the frequency tuning step value in a large range. When the receiving frequency value is extremely large, the split adjustment mode can be entered by pressing the knob encoder. This method realizes a method for operating a complex user interface and adjusting an extremely long value with a single knob. In actual device applications, this method can omit a large number of physical digital buttons and function buttons, thereby reducing device costs, improving the comfort of the device appearance, and reducing the complexity of device operation.

[0094] In summary, this application, by introducing encoder knobs and buttons, realizes that a single knob can operate complex user interfaces and adjust long values, and can omit a large number of physical digital buttons and function buttons, thereby reducing equipment costs, improving the appearance and comfort of equipment, and reducing the complexity of equipment operation. The auxiliary device has a variety of practical functions. On the basis of a large-capacity mobile power supply, it realizes the integration of a full-band single-double-sideband radio, a digital music player, a UV-band high-frequency receiver, a Bluetooth digital audio master-slave machine, an FM transmitter, a network audio player, a recorder, a network time and weather information terminal, a CNC lighting lamp, a USB sound card controller, and a screen display terminal. The receiving device can quickly tune to the target menu or receiving frequency, and the user can quickly set the corresponding function without operating a large number of button settings.

However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
