The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure.

Example one
Fig. 1 is a flowchart of a method for processing a driver of an input device, which is applicable to a case where an optimization process is performed on a driver of the input device, and which is performed by a driver processing apparatus of the input device, where the apparatus can be implemented by software and/or hardware and can be integrated in the input device according to a first embodiment of the present invention. As shown in fig. 1, the driving processing method of the input device in the present embodiment includes the following steps:
and S110, detecting the voltage state of the target voltage generated when the target trigger point is triggered through the input device.
The embedded device detects a voltage state of a target voltage generated when a device user triggers a target trigger point through an input device, wherein the input device can be a touch screen, a Bluetooth/USB mouse and other input devices, and the voltage state can be a voltage stable state and a voltage unstable state.
In this embodiment, optionally, the target voltage may be a voltage in a preset direction obtained by converting the trigger of the input device to the target trigger point by using an analog-to-digital converter.
In an alternative to this embodiment, the embodiment of the invention may be combined with each of the alternatives in one or more of the embodiments described above. Detecting a voltage state of a target voltage generated upon triggering of a target trigger point by an input device may include the following steps a1-a 2:
step a1, determining a trigger duration for triggering the target trigger point via the input device.
Step a2, if it is determined that the trigger duration is greater than or equal to a preset voltage stabilization time threshold of the analog-to-digital converter ADC, determining that the target voltage is in a voltage stabilization state.
The embedded device determines the trigger duration when the target trigger point is triggered through the input device, if the trigger duration is greater than or equal to a preset voltage stabilization time threshold of the analog-to-digital converter ADC, the target voltage is determined to be in a voltage stabilization state, the voltage stabilization time threshold of the analog-to-digital converter ADC is a parameter of the analog-to-digital converter ADC, the target voltage is determined when the analog-to-digital converter ADC is constructed, the target voltage is set in a driving program of the input device, and the position coordinate of the target trigger point is measured when the trigger duration reaches the voltage stabilization time threshold of the analog-to-digital converter ADC. For example, when the input device is a touch screen, the target trigger point may be a position where the operator wants to touch the click, and the trigger duration is a time from when the finger touches the touch screen to when the finger leaves the touch screen.
By adopting the technical scheme, the trigger duration time when the target trigger point is triggered is ensured to be more than or equal to the voltage stabilization time threshold of the analog-to-digital converter ADC by optimizing the driving program of the input equipment, so that the voltage value of the trigger point is stable when the interrupt program instruction is sent to measure the position coordinate point, the precision of determining the position coordinate value of the trigger point can be improved, and the technical effects of preventing mistaken touch and mistaken touch can be achieved.
And S120, if the target voltage is detected to be in a voltage stable state, starting an interrupt service program, and measuring at least two position coordinate values of the target trigger point through the interrupt service program.
When the embedded device detects that the target voltage is in a voltage stable state, an IRQ interrupt service program is started, and at least two position coordinate values of the target trigger point are obtained through measurement of the interrupt service program.
And S130, reporting a coordinate input event of the input equipment to the application layer according to the at least two position coordinate values, so that the application layer can acquire the input coordinate.
The embedded device reports a coordinate input event of the input device to the application layer according to at least two position coordinate values to enable the application layer to acquire input coordinates, the application layer can be various window systems of a user space, and the coordinate input event is obtained by packaging measured coordinate points obtained by clicking through an input device driver.
According to the technical scheme, the voltage state of the target voltage generated when the target trigger point is triggered through the input device is detected, whether the detected target voltage is in the voltage stable state or not is judged, if yes, the interrupt service program is started, the interrupt service program can measure at least two position coordinate values of the target trigger point, the accuracy of determining the position coordinate values of the trigger point is improved, and the technical effect that misoperation is caused on the input device due to mistaken touch and mistaken touch is avoided.
Example two
Fig. 2 is a flowchart of another driving processing method for an input device according to the second embodiment of the present application. Embodiments of the present invention are further optimized on the basis of the above-mentioned embodiments, and the embodiments of the present invention may be combined with various alternatives in one or more of the above-mentioned embodiments. As shown in fig. 2, the method for processing driving of an input device according to an embodiment of the present invention may include the following steps:
s210, detecting the voltage state of the target voltage generated when the target trigger point is triggered through the input device.
And S220, if the target voltage is detected to be in a voltage stable state, starting an interrupt service program, and measuring at least two position coordinate values of the target trigger point through the interrupt service program.
And S230, if the fact that the target trigger point triggering operation is not finished before the conversion of the analog-to-digital converter is finished is determined, determining whether the coordinate values of at least two positions meet a preset coordinate removing condition.
If the embedded device determines that the target trigger point is still operated by an operator before the analog-to-digital converter is converted, determining whether at least two position coordinate values meet a preset coordinate removing condition, wherein the preset coordinate removing condition can be that all the measured position coordinate values are removed under the condition that a certain condition is triggered, and all the measured position coordinate values are reserved if the condition is not triggered.
And S240, reporting a coordinate input event of the input equipment to the application layer according to the at least two position coordinate values if the at least two position coordinate values do not meet the coordinate rejection condition.
The coordinate removing condition comprises that the difference value between the horizontal coordinate value and the vertical coordinate value of each position coordinate value obtained by measurement is larger than a preset point position threshold value.
The method includes the steps that if at least two position coordinate values obtained by measurement of the embedded device do not meet a coordinate rejection condition, a coordinate input event of the input device is reported to an application layer according to the at least two position coordinate values, the coordinate rejection condition includes that a difference value between an abscissa value and an ordinate value of each measured position coordinate value is larger than a preset point location threshold, the preset point location threshold can be defined according to actual situation requirements, exemplarily, the coordinate rejection condition can be that when a difference between an x coordinate or a y coordinate of an nth measurement and an x coordinate or a y coordinate of an N-1 th measurement is larger than 5 point locations, all the position coordinate values of the N measurements are discarded, wherein N is larger than or equal to 2.
By adopting the technical scheme, the measured value with overlarge position coordinate difference, namely the measured value with overlarge error can be discarded according to the coordinate elimination condition, so that the technical effect of reducing the difference range of the reported position coordinate point as much as possible and improving the precision is achieved.
On the basis of the above embodiments, the present embodiment may be optionally combined with various alternatives in one or more of the above embodiments. Reporting a coordinate input event of the input device to the application layer according to at least two position coordinate values, which may include the following steps B1-B2:
and step B1, calculating the position coordinate average value of at least two position coordinate values, and generating the coordinate input event of the input equipment according to the position coordinate average value.
And step B2, reporting the generated coordinate input event to an input device node registered under a system kernel file system through an event reporting function in a system kernel of the embedded device, and reading the coordinate input event by a window of an application layer to acquire an input coordinate.
The embedded device calculates a position coordinate average value of at least two position coordinate values, generates a coordinate input event of the input device according to the position coordinate average value, reports the generated coordinate input event to an input device node registered under a system kernel file system through an event reporting function in a system kernel of the embedded device, and is used for a window of an application layer to read the coordinate input event and obtain an input coordinate.
The input device node is a node for registering an input device driver under the kernel file system when the input device is connected to the embedded device. Exemplarily, as shown in fig. 3, fig. 3 is an input event generation mechanism under a Linux system, where a Linux-based embedded device is connected to a coordinate input device (e.g., a hot-plug usb mouse) at or after power-on, an input device driver registers a corresponding input device node for the coordinate input device under a kernel/dev/input file system, and the input device drivers can measure coordinate points when the coordinate input device is clicked and encapsulate them into input events, and in the operation of the input device, the input events are converted into input events by the corresponding input device drivers and reported to the corresponding input device node through a Linux kernel function input _ event (), and then the input device node is read by using a window system in a space to obtain coordinate input events to obtain position coordinate values of a target trigger point.
According to the technical scheme of the embodiment, whether the coordinate rejection condition is executed or not is judged by determining whether the operation triggered by the target trigger point is finished or not before the conversion of the analog-to-digital converter is finished, if not, the coordinate input event of the input device is generated according to the average value of at least two position coordinate values, the coordinate input event is reported to the input device node, the window of the application layer reads the coordinate input event to obtain the input coordinate, the technical effect of improving the precision of the reported position coordinate point is achieved, and the response precision and the operation experience of the upper application space can also be improved.
