In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
First related terms are explained below：
Linux：It is a set of free class Unix operating systems using with Free propagation, is one and is based on POSIX and UNIX
Multi-user, multitask, the operating system for supporting multithreading and multi -CPU.It can run main unix tool software, using journey
Sequence and procotol.It supports 32 and 64 hardware.Linux inherits design philosophys of the Unix using network as core, is one
The stable multiple-user network operating system of individual performance.
The method that the present invention proposes a set of monitoring system button in inner nuclear layer, being capable of effective physics in detecting system
The situation that button is pressed or lifted.
In one embodiment of the present of invention, as shown in figure 1, the button monitor method based on Linux inner core is including following
Step：
S101, operating system open the button monitoring file under preset path, and button monitoring file correspondence is by Linux
Core virtually turns to the specified button of device node, and the button monitoring file, which includes one, to be used to monitor the self-defined of the specified button
The polling cycle of detection button is provided with function, the SQL and the event functions of key-press status are reported；
S102, operating system read the button monitoring file according to the polling cycle of setting with polling mode, and this is pressed
Content in key monitoring file is read in design variables；
Whether if S103, reading successfully, it is preset value to judge the content in the design variables, and preset value correspondence is specified
The state value that button is pressed or lifted, if so, then performing step S104；
S104, according to event functions key-press status is reported, specifically report system application layer.
Preferably, button monitoring file is pre-stored in the device file of linux system.
Further, if the content in the button monitoring file is read successfully, the value more than or equal to 0 is can return to, if reading
Failure is taken then to return to the value less than 0.
If as shown in Fig. 2 the content also included in step S105, the button monitoring file reads failure, calling default
Printf print error message.
In step S102, when operating system reads the button monitoring file with polling mode, a polling cycle is often completed,
The polling cycle for detecting button then is passed into a delay function to realize that delay, delay enter back into poll next time after terminating
Cycle.
In step S104, key-press status can be reported into system application layer especially by the form of function pointer.Function refers to
A categorical variable can be designed in pin, this makes it possible to report away various key-press events.This design is carried significantly
The high autgmentability of the function, the extension for other key-press events of later stage serves extraordinary compatible act on.
In the preferred embodiment of the present invention, a SQL set_ for being used to monitor the specified button can be designed
Delt_ in key_listener (long delt_time, void ((void*)) key_fun (int fun_type)), the function
What time was represented is the time slice for detecting button, i.e. polling cycle, and what key_fun was represented is to detect the readjustment letter after button
Number, fun_type represents the key-press event information reported.
Designed SQL set_key_listener (long delt_time, void ((void*)) key_
Fun (int fun_type)) realize that logical method is as follows：
1st, the function defined in check_key.h files is declared
Need the definition of function being stored in check_key.h header files in C language development process, so subsequently
The mode of header file can be quoted to call the function included in header file.The method declared in the present embodiment in header file
It is as follows：
set_key_listener(long delt_time,void((void*))key_fun(int fun_type))；
Next a simple illustration is done to this method.Set_key_listener is the title of the function of definition, should
Comprising 2 parameters in function, one is delt_time, what this parameter was represented is the polling cycle of the detection of button,
What ((void*)) key_fun (int fun_type) was represented is the callback information of function, is just passed through after key-press event is detected
The mode of ((void*)) key_fun (int fun_type) function pointer passes key information.
Benefit analysis：
A) definition of function is stored in check_key.h header file, so subsequently only needed when in use
To quote header file by include sentences is calling for realizable function
B) delt_time variables are devised, outside delt_time variables can be passed through so in the detection cycle of button
The detection cycle come inside fine regulation of value, it is ensured that the accuracy requirement of button detection and the balance of resource overhead.
C) type information of button is passed by the form of ((void*)) key_fun (int fun_type) function pointer
Pass the external world, the state flow of exposure button.
2nd, button poll detection method
Button detection is carried out in the present embodiment by way of button poll, polling method is exactly constantly to detect button
Whether it is pressed.All all files in linux system, so button is invented a device node and hung over by kernel
Under/dev/input/even files, judge whether button is pressed by constantly reading the value of this document.
Next describe how to read/dev/input/even device files.Pass through calling system body
Open methods open a device file, specifically int key_fd=open ("/dev/input/event ", O_
RDONLY) method opens a file.Wherein/dev/input/event represents the device file name for needing to open, O_
It in unfolding mode, the present embodiment is to open device file by read-only mode that what RDONLY was represented, which is,.Open functions will return to one
Individual device file descriptor, the device file descriptor is received using key_fd.
If key_fd, which is more than 0, represents File Open success, if key_fd, which is less than 0, represents file open failed.If
File open failed then needs to terminate to read and by the way that error message is printed, specifically printf (" open/dev/
input/event device error！N ") mode carrys out print error message.If File Open success, is next accomplished by
Read the information in file.
File, which is read, to be realized by polling mode, is realized wireless circulating using while (true) modes, is wirelessly being followed
The continuous content of reading/dev/input/event device nodes in ring.The mode of specific reading/dev/input/event contents
It is read (key_fd ,s ＆t, sizeof (t)), the content of this function is that the content in key_fd files is read into this change of t
In amount, the variable may be configured as global variable.If file reads successfully read (key_fd ,s ＆t, sizeof (t)) and will returned greatly
In the value equal to 0, if the value for being less than 0 will be returned to by reading failure read (key_fd ,s ＆t, sizeof (t)).
If reading have failed, it is necessary to printf (" read/dev/input/event device error！\n")
Mode carrys out print error message.
It is accomplished by taking out the content in variable t into the content judged in t is how many if read successfully.If t's
Value is 0 to mean that button is pressed, if t value is 1 to mean that button is lifted.
Complete every time after a read cycle, it is necessary to call a delay function sleep to transmit the detection of coming in simultaneously
Cycle delt_time is delivered in sleep functions, that is, calls sleep (delt_time) functions to realize delay, delay
Afterwards enter next time call the cycle.Such benefit is saving system of being tried one's best in the case of ensure that user's accuracy of detection
Expense.
Just the event being pressed is reported by the form of function pointer after button is pressed when detecting.
Benefit analysis：
A) in poll detection, equipment is opened and reading has been done verification and judged, if opening could successfully read, opens and loses
Lose meeting print prompt information and inform caller.
B) detection key-press event precision is adjustable, and we can set poll frequency by this parameter of delt_time, this
Sample ensures that caller can also reach the purpose for saving system resource while accuracy requirement is reached.
C) detect after key-press event and to be reported by function pointer ((void*)) key_fun (int fun_type),
Listener can timely get button situation of change.
3rd, the data readjustment logic of button is detected
When being pressed by detecting button in step 2, call back function (void*) key_fun will be passed through
(int fun_type) reports away key-press event.Implement is if by read (key_fd ,s ＆t, sizeof (t))
The value for the t that function is read is greater than being shown to be equal to 0, and a button is pressed, now needs call function pointer key_
Fun (KEY_DOWN) reports away key-press event, and what wherein KEY_DOWN was represented is a customized constant, the constant
Value be 1.
Why have a fun_type type adjust back away be for convenience other compatible key-press events of later stage carry out it is pre-
Work is stayed, the autgmentability of the function is improved.
By the call method of above-mentioned function pointer, we just inform the trigger event of button to outside, so outside
Portion can just get the information that button is pressed in real time.
Benefit analysis：A categorical variable is devised in function pointer (void*) key_fun (int fun_type), this
Sample I various key-press events can just can be reported away.It is this to design the autgmentability for substantially increasing the function,
Extension for other key-press events of later stage serves extraordinary compatible effect.
