Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description, it is clear that the described embodiments are merely a part of the embodiments of the present invention, the embodiment being not all of, and is based on this hair
Embodiment in bright, those of ordinary skill in the art's every other implementation obtained under that premise of not paying creative labor
Example, shall fall within the protection scope of the present invention.
On the one hand the embodiment of the present invention provides a kind of method that high-precision adjusts special-effect parameter, realize process such as Fig. 1 institute
Show, specifically include:
Step S101: the external equipment for adjusting special-effect parameter is connected.
Preferably, above-mentioned external equipment can support HID protocol, can be directly connected by USB interface with host.
Step S102: setting monitoring thread and the output data for obtaining the external equipment.Specifically, monitoring thread monitors
The variation of the corresponding output data of whole hardware of external equipment, and be stored in buffer area, so as to the adjusting of subsequent special-effect parameter
System can carry out the modification of corresponding parameter according to the output data of variation.
Step S103: parsing the output data and modifies the corresponding special-effect parameter in special-effect parameter regulating system,
The high-precision for carrying out the special-effect parameter is adjusted.
Specifically, when special-effect parameter regulating system gets the parameter after needing to parse, the completion pair directly in system
Answer the modification of parameter.
The method provided in an embodiment of the present invention for carrying out special-effect parameter adjusting by external equipment, keeps parameter regulation more clever
It is living, it can be improved the speed of parameter regulation, and parameter regulation can be made more accurate.
The embodiment of the present invention with external equipment is to support in this implementation column second is that further description to embodiment one
HID protocol and adjusting with multiple adjustable buttons, knob, screw etc. is illustrated for the Wave Panel of component, and
Do not regard it as and be limited, concrete implementation process is as follows:
Step S201: external equipment Wave Panel is connected by USB interface.
Step S202: monitoring thread is set after successful connection and opens the monitoring thread.
Thread is a single sequential control process in application program.It is complete that multiple threads are run simultaneously in single program
At different work, referred to as multithreading.One application program includes a main thread and multiple sub threads, is created by main thread each
A sub thread, each thread independent operating, communicates with each other, shared resource, can efficiently use system resource using multithreading, mention
High execution efficiency.
Wave Panel is with the every 40ms of polling mode to signal conditioning components such as key, knob and screws on panel
State detected, and generate output data, therefore except including parameter tune in special-effect parameter regulating system in this implementation column
It saves except main thread, then a monitoring thread is set for reading the output data of Wave Panel generation, the parameter
It adjusts main thread to run parallel with the monitoring thread, independently of one another.
Specifically, the monitoring thread of setting starts and remains operational automatically after Wave Panel opening.
It preferably, include the signal conditioning components such as multiple adjustable buttons, knob, screw on Wave Panel panel,
Therefore, after Wave Panel and the successful connection of special-effect parameter regulating system, user can preset each Signal Regulation group
Corresponding relationship between part and special-effect parameter.
Step S203: monitoring thread reads the data that equipment exports according to fixed time interval, and 26 words are arranged
The buffer area of section saves the data of output.
Wave Panel is with the every 40ms of polling mode to signal conditioning components such as key, knob and screws on panel
State detected, can not detect the state change of signal conditioning component on panel in real time, but in this implementation column
The monitoring thread of setting reads the data of Wave Panel output according to fixed time interval, and the fixed intervals of setting are can be with
It is configured according to user demand.
The output data length of Wave Panel be 26 bytes, wherein preceding 41 bit of 0-5 byte respectively represent 41 by
Key, be worth indicates to press for 1, and 0 indicates to lift, and separately has 7 bits unused, is set as 0；6-18 byte respectively represents 13 encoders
(encoder includes 9 knobs, 3 dial and 1 jog wheel)；Every 2 byte of 19-24 byte represents 1 screw (2 byte
Respectively represent the x-axis and y-axis of screw)；25 bytes are left unused.Therefore, monitoring thread should be arranged one 26 in this implementation column
The buffer area of byte receives and stores the output data of Wave Panel.
Step S204: monitoring thread analyzes each byte of output data, to judge whether the key in equipment is pressed
Under；Whether knob, screw etc. change, if any one state for adjusting component changes, monitoring thread is to notify
Form of message notifying parameters adjust main thread, do not change, continue to monitor.
Step S205: parameter regulation main thread receives the notification message of monitoring thread, is come interpretation according to message content
Which button is pressed or knob value is changed, to judge the variation of corresponding parameter, conversion accuracy modifies corresponding spy
Skill parameter.
Specifically, then modifying the corresponding parameter of button when the notification message received is that button is changed；If it is
Knob, screw or other values for adjusting component are changed, then are converted accordingly according to the precision of corresponding parameter, will
Data value after conversion is assigned to special-effect parameter or increases to variable quantity on the current parameter value of special-effect parameter, realizes stunt ginseng
Several adjustings.
The method for carrying out special-effect parameter adjusting by external equipment Wave Panel in the embodiment of the present invention, passes through monitoring
Button, knob, screw or other state changes for adjusting component make parameter to modify special-effect parameter value on Wave Panel
Adjusting is more flexible, can be improved the speed of parameter regulation, and parameter regulation can be made more accurate.
The embodiment of the present invention three provides a kind of high-precision adjusting special-effect parameter system, which constitutes as shown in figure 3, packet
It includes:
External equipment connection unit 31, for connecting the external equipment for adjusting special-effect parameter.
It reads the newspaper and accuses thread setting unit 32, for monitoring thread to be arranged and obtains the output data of the external equipment.
Resolution unit 33, for parsing the output data and modifying the corresponding stunt in special-effect parameter regulating system
Parameter, the high-precision for carrying out the special-effect parameter are adjusted.
Wherein, the external equipment supports human interface device HID protocol.
Specifically, the system further include:
Output data monitoring unit 34, the variation of the output data for monitoring the external equipment, and by the number of variation
According to being stored in buffer area.
The output data monitoring unit 34 monitors the variation of the output data of the external equipment with Fixed Time Interval.
It is provided in an embodiment of the present invention that special-effect parameter regulating system is carried out by external equipment, keep parameter regulation more clever
It is living, it can be improved the speed of parameter regulation, and parameter regulation can be made more accurate.
Through the above description of the embodiments, those skilled in the art can be understood that the present invention can lead to
Software realization is crossed, the mode of necessary general hardware platform can also be added to realize by software.Based on this understanding, this hair
Bright technical solution can be embodied in the form of software products, which can store in a non-volatile memories
