The embodiments of the present application will be described in further detail with reference to the drawings attached hereto.
Referring to fig. 1, in one embodiment of the present application, a dynamic dimming method for a rotary knob encoder is provided, the main steps of the method are described as follows:
s10: the control unit identifies a first change state of the knob encoder, initializes a timing counter, and judges the rotation direction of the knob encoder according to the level change received by the control unit in the first change state;
s20: the control unit identifies a second change state of the knob encoder, acquires a current time count value of the timing counter, and acquires a preset interval value corresponding to the current time count value based on the current time count value;
and S30, dynamically adjusting the dimming value of one rotation of the knob encoder according to the rotation direction and the preset interval value until the target dimming value is adjusted.
As shown in fig. 2, the knob encoder is electrically connected to the input a end and the input B end of the control unit, the first output port of the knob encoder is electrically connected to the input a end of the control unit, the second output port of the knob encoder is electrically connected to the input B end of the control unit, and the control unit can receive the digital signal output by the knob encoder. The control unit is an MCU (microprogrammed control unit), and a timing counter is integrated in the MCU system.
Preferably, at intervals, the timing counter determines whether the current time count value is 0, and if not, the current time count value is subtracted by 1 until the current time count value is equal to 0. In this embodiment, the time interval T is set to 3.3 milliseconds, the timer counter is not interfered in the whole process, the current time count value is checked every 3.3 milliseconds to determine whether the current time count value is 0, and if not, the time count value is subtracted by 1 every 3.3 milliseconds until the time count value is equal to 0. The change of the time count value can be estimated in the process of rotating one grid through the knob encoder, the time for rotating one grid of the knob encoder by a user is the time used by multiplying the change of the time count value by 3.3 milliseconds, and the speed for rotating one grid of the knob encoder by the user can be estimated on the premise that the rotary displacement of each grid of the knob is the same. When the time count value of the knob encoder rotated by a user has small variation, namely the time used is short, the user wants to quickly adjust the knob encoder, and the expected dimming value is greatly changed; when the user rotates a knob encoder, the time count value has a large variation, i.e. the time taken is long, which represents that the user wants to slowly adjust the knob encoder, a fine variation of the dimming value is expected. Therefore, the dimming value can be adjusted by setting different interval values according to the time and speed of a user rotating a knob encoder.
Preferably, the control unit receives a signal from the knob encoder, and recognizes a first change state of the knob encoder, where the first change state is an instant when the knob encoder rotates. Judging the rotation direction of the knob encoder according to the sequence of level changes of an input end A and an input end B of the control unit in a first change state;
if the input end B of the control unit receives the level change before the input end A receives the level change, the knob encoder is judged to rotate clockwise;
if the input end A of the control unit receives the level change before the input end B receives the level change, the knob encoder is judged to rotate anticlockwise.
Specifically, the control unit receives a digital signal output by the knob encoder, and when the knob encoder is in a static and non-rotating state, the input A end and the input B end of the control unit are simultaneously high level and/or low level when receiving the digital signal. At the moment of rotating the knob encoder, the level received by the input A end and the input B end of the control unit changes, and the high level is converted into the low level or the low level is converted into the high level. As shown in fig. 3, when the control unit recognizes a first change state, where the first change state is state 1 in fig. 3, and the electrical levels received by the input a end and the input B end of the control unit change from a high electrical level to a low electrical level, and the electrical level received by the input B end of the control unit preferentially changes from the electrical level received by the input a end, it may be determined that the knob encoder rotates clockwise; as shown in fig. 4, when the control unit recognizes that the first change state is the state 1 in fig. 4, the levels received by the input a end and the input B end of the control unit change, and the levels change from high level to low level, and the level change received by the input a end of the control unit is preferentially changed from the level received by the input B end, then it can be determined that the knob encoder rotates counterclockwise.
Preferably, if the knob encoder rotates clockwise, the dimming value of the knob encoder is increased according to a preset interval value; and if the knob encoder rotates anticlockwise, reducing the dimming numerical value of the knob encoder according to a preset interval value. Specifically, the control unit judges that the user rotates the knob encoder clockwise, and when the user rotates the knob encoder one grid, the dimming numerical value of the knob encoder is added with a preset interval value; the control unit judges that the user rotates the knob encoder anticlockwise, and when the user rotates the knob encoder one grid, the dimming value of the knob encoder subtracts a preset interval value once. Through judging the rotation direction of the knob encoder, the dimming numerical value is increased or reduced at any time, so that the dimming numerical value is more convenient and efficient to adjust.
Preferably, a time count value interval table is preset in the control unit, at least two count value intervals are divided in the time count value interval table, each count value interval is correspondingly provided with a preset interval value, and the number of the count value intervals can be freely set;
and judging a count value interval to which the current time count value belongs, acquiring a preset interval value corresponding to the count value interval, and adjusting the dimming value of the knob encoder according to the preset interval value corresponding to the count value interval.
Specifically, as shown in fig. 3 and 4, the control unit obtains a current time count value of the timing counter at the instant when the control unit receives the second change state of the knob encoder, determines a count value interval to which the current time count value belongs by referring to a time technical value interval table preset in the control unit, obtains a preset interval value corresponding to the count value interval, and adjusts the dimming value of the knob encoder according to the preset interval value. And estimating the time for rotating a lattice knob encoder according to the counting value interval to which the current counting value belongs, and further performing quick adjustment of large numerical span on the dimming numerical value according to different preset interval values or performing fine adjustment of small numerical span on the dimming numerical value.

If the current time count value is judged to belong to the first count value interval, acquiring a first preset interval value corresponding to the first count value interval, and adjusting the dimming value of the knob encoder according to the first preset interval value;
if the current time count value is judged to belong to the second count value interval, a second preset interval value corresponding to the second count value interval is obtained, and the dimming value of the knob encoder is adjusted according to the second preset interval value;
if the current time count value is judged to belong to a third counting value interval, a third preset interval value corresponding to the third counting value interval is obtained, and the dimming value of the knob encoder is adjusted according to the third preset interval value;
if the current time count value is judged to belong to a fourth count value interval, a fourth preset interval value corresponding to the fourth count value interval is obtained, and the dimming value of the knob encoder is adjusted according to the fourth preset interval value;

the third interval is (150, 200), and the corresponding third preset interval value is 3;
the fourth counting value interval is (100, 150), and the corresponding fourth preset interval value is 2;
the fifth counting value interval is [0,100], and the corresponding fifth preset interval value is 1.
Specifically, for example, the control unit recognizes a first change state of the knob encoder, initializes the timing counter, and in the first change state, the input B end of the control unit receives a level change before the output a end receives a level change, and determines that the rotation direction of the knob encoder is clockwise; and identifying a second change state of the knob encoder, rotating the knob encoder by one grid to obtain a current time count value of the timing counter at the moment, comparing the current time count value with a time count value interval table preset in the control unit, if the judgment result shows that the current time count value belongs to a first count value interval, obtaining a first preset interval value corresponding to the first count value interval, and adding a first preset interval value to the dimming value of the knob encoder.

The numerical value interval of the time count value is divided into 5 different numerical value intervals, so that the regulation rate habit of a user is better met, and the dimming efficiency of the dimming numerical value of the adjusting knob encoder can be improved. The first counting value interval is between more than 250 and less than or equal to 300, which represents that the time range for rotating a knob encoder by a user is between 0 and 0.165 seconds, and the first preset interval value is set to be 5; the second counting value interval is between more than 200 and less than or equal to 250, which represents that the time range for the user to rotate one knob encoder is between 0.165 and 0.33 seconds, and the second preset interval value is set to be 4; the third counting value interval is between more than 150 and less than or equal to 200, which represents that the time range for the user to rotate one knob encoder is between 0.33 and 0.495 seconds, and at this time, the third preset interval value is set to be 3; the fourth counting value interval is between more than 100 and less than or equal to 150, which represents that the time range for the user to rotate one knob encoder is between 0.495 and 0.66 seconds, and the second preset interval value is set to be 2; the fourth counting value interval is between greater than 0 and less than or equal to 100, which represents that the time for the user to rotate one knob encoder ranges from 0.66 to 0.99 seconds, and the first preset interval value is set to be 1.

When the dimming value of the knob encoder is adjusted to be increased or decreased according to the preset interval value, a value greater than 255 or less than 0 may occur, and at this time, the lamp does not have corresponding brightness. When the dimming value of the knob encoder is adjusted to be less than 0, setting the dimming value to be 0; when the dimming value of the knob encoder is adjusted to be larger than 255, the dimming value is set to be 255, and the dimming value is guaranteed to change between effective values.
