Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of an eye chart testing method according to an embodiment of the present disclosure. The method comprises the following steps:
s101: and acquiring target data and writing the target data into a target file.
Some or all of the steps of the eye pattern testing method provided by this embodiment may be performed by a specific electronic device, and the specific type and model of the electronic device are not limited. For example, in one possible embodiment, the electronic device may be a display device, such as a VR (Virtual Reality technology) device, an AR (Augmented Reality technology) device, or other device having a display screen. In another possible implementation, the electronic device may be a device having a USB (Universal Serial Bus) interface. It should be noted that, when the electronic device operates, data in the register and the memory of the electronic device cannot be directly read and written. The eye pattern test is important for electronic equipment which uses differential signals for data transmission, and if the eye pattern test is not passed, the signal transmission is problematic, and communication abnormity can be caused during use. Such an abnormality differs depending on the kind of electronic device, and for example, in the case of a display device, the abnormality may be a screen-splash abnormality; for an electronic device with a USB interface, the abnormality may be an abnormality that cannot be identified by the USB interface, or an abnormality that a transmission result is wrong when data transmission is performed by using the USB interface.
The target data may be input by a user to modify data in the register and the memory, and the embodiment does not limit the specific size, format and quantity of the target data, and may be set according to actual needs. It is understood that the target data may be plural, and are respectively used for writing to different positions of the target file; the format of the target data can be a directly written format, or a format convenient for transmission or a format with a small data size, and the target data can be firstly subjected to format conversion and then written into the target file during writing. The embodiment does not limit the specific manner of acquiring the target data, and for example, the target data may be acquired from a specified path, or the target data may be acquired from a specified device or terminal. In a possible implementation manner, the target data may be obtained by using a test interface on the electronic device, where a specific type of the test interface is not limited, and for example, the test interface may be an ADB (ADB Debug Bridge) interface, which is a port for developing and debugging.
The target file is specifically a file storing register data, and is also a file allowing register reading, and the specific format and the like of the target file are not limited. The target file also allows writing of target data, and it is understood that the register data in the target file is the full data of one register, which corresponds to the register, and since the number of registers may be one or more, the data corresponding to one or more registers may also be recorded in the target file. Further, the target data written into the target file may be used to replace all data in the target file, or may be used to replace or modify part of data in the target file. For example, when register data corresponding to a plurality of registers is recorded in the target file, the target data may be used to replace data corresponding to a certain register in the target file. And reading the target data from the register through the target data writing so as to modify the data in the register during the operation of the electronic equipment. The target data is transferred by using the target file, and the limitation that the data in the register cannot be directly modified is avoided by adopting a mode of writing first and then reading, so that the data in the register is modified.
S102: and reading the register data in the target file to the register.
It is understood that the embodiment does not limit the specific execution time for reading the register data in the target file to the register, i.e. the time when the target file is read. In one embodiment, the data in the target file can be read to the register immediately after the target data is detected to be written into the target file; in another embodiment, the register data in the target file may be read to the register when the read instruction is detected, and whether the read instruction is generated is independent of whether the target data is written in the target file. The embodiment also does not limit the way in which the control register reads the register data in the target file, and the specific way may refer to related technologies, which are not described herein again. The target file is read through the control register, the register data in the target file are obtained and stored, namely the register data in the target file are read to the register, and the data in the register can be replaced under the condition that the device software is not recompiled and the electronic device is not restarted.
It should be noted that, when reading the register data each time, the target file may be read in full, that is, all the data in the target file are read to the register; in another embodiment, the target file may be partially read, that is, a part of data in the target file is selected to be read to the register, so as to reduce the time required for reading the register data and improve the efficiency of the eye pattern test.
S103: and refreshing the register data in the register to the memory, and carrying out eye pattern test after the refreshing is finished.
In order to perform an eye test using new register data, the electronic device operates using data in the memory, and therefore, after the register data in the target file is read to the register, the register data needs to be refreshed in the memory. The embodiment does not limit the specific manner of refreshing the register data to the memory, and for example, for display devices such as VR devices and AR devices, the register data may be refreshed to the memory by turning off and turning on the display screen. After the new register data is refreshed to the memory, the electronic device can perform a new eye pattern test by using the new register data. Software compiling is not needed in the two eye pattern tests, and the electronic equipment is not needed to be restarted, so that the time needed by the software compiling and restarting is shortened, and the efficiency of the eye pattern test is improved.
By applying the eye pattern testing method provided by the embodiment of the application, the target data is obtained from the outside and written into the target file. Since the register can also read the data in the file when the device is in operation, the register data in the target file can be read into the register. The target data is transferred through the target file, namely the data is written into the target file firstly and then read to the register, so that the data in the register can be updated when the equipment works, and the limitation that the data in the register cannot be directly modified is relieved by reading the target file. After the register data in the register is refreshed to the memory, the device can utilize the new data to perform the eye pattern test. The method can reduce the times of modification and compilation of software and the times of restarting of the equipment, updates the parameters in real time under the condition that the equipment is not shut down, reduces the time required by eye pattern testing, improves the testing efficiency, and solves the problems of longer testing time and lower efficiency in the related art.
Based on the foregoing embodiments, the present embodiment will specifically describe several steps in the foregoing embodiments. Wherein, the step S101 may include:
step 11: and acquiring target data and corresponding pointing information by using the ADB port.
Step 12: and determining the register data to be updated of the target file according to the pointing information, and updating the register data to be updated by utilizing the target data.
In this embodiment, the target data may be obtained through the ADB port, and it should be noted that the target data is not full and complete register data, that is, data for overwriting all data in the target file. Therefore, in order to accurately write the target data into the target file, the direction information corresponding to the target data can also be acquired through the ADB port. The target data and the pointing information may be acquired simultaneously, or the target data and the pointing information may be acquired twice respectively, and the acquisition condition of the target data and the pointing information is recorded by using the corresponding flag bits, for example, 0 is obtained when all the target data and the pointing information are not acquired, and 1 is modified after all the target data and the pointing information are acquired. After the target data and the pointing information are determined to be obtained, register data to be updated are determined in the target file according to the pointing information, and the register data to be updated are updated by utilizing the target data. In one embodiment, the register data to be updated is all data corresponding to a certain register, and in another embodiment, the register data to be updated is a part of the register data corresponding to a certain register, which needs to be replaced. After determining the register data to be updated, it may be replaced with the target data. Specifically, the original data may be deleted first and then the target data may be written, so that the unwritten portion may be determined when the write failure requires rewriting, so as to directly write the unwritten portion of the target data. In another embodiment, the target data may be directly utilized to perform the overlay update on the register data to be updated.
By acquiring the pointing information when the target data is acquired and writing the target data according to the pointing information, the volume of the target data can be reduced, the full amount of data corresponding to the target file does not need to be sent during each transmission, and waste of communication resources is avoided.
Based on the foregoing embodiment, if the target file records register data corresponding to a plurality of registers, the step S102 may include:
step 21: and acquiring a plurality of register data and respectively corresponding data identifications from the target file.
Step 22: and determining a target register corresponding to each register data according to the data identification.
Step 23: and writing the data of each register into the corresponding target register.
Because the number of the registers is multiple, the target file stores register data corresponding to the registers, in order to prevent the electronic device from working abnormally due to a register data reading error, in this embodiment, a corresponding data identifier is set for each register, and the data identifier corresponds to the register data. The data identifier may specifically be information such as a data number, a register number, a position in a target file, and the like, and may perform an identification function, and specific content may be set as needed. When the register data is read to the register, the corresponding relation of the register data-the data identifier-the register can be utilized, the target register corresponding to each register data is determined according to the data identifier, and the register data is written into the corresponding target register after the target register is determined.
Further, since the target data may be non-full data, only part of the data in the target file is changed and part of the data is not changed after the target data is written into the target file. This may result in some register data being changed in the destination file while other register data is unchanged. Therefore, before writing each register data into the corresponding target register, the method may further include:
step 31: and respectively judging whether the data of each register changes.
Step 32: and if the change occurs, determining the register data as the target register data.
Accordingly, writing the data of each register into the corresponding target register, that is, step 23 may include:
step 33: and writing the target register data into the corresponding target register.
After the target registers corresponding to the registers are determined, whether the data of the registers change or not can be judged, namely, the target data written at this time modifies the data of the registers. If some register data is changed, it must be read to the register in order to modify the data in the register, so that it can be determined as the target register data. If the data in a register is not changed, the data in the target register is not changed no matter whether the register is read to the corresponding target register, so in this embodiment, the register data which is not changed may not be read to the corresponding target register, so as to reduce the time required for reading the data.
Based on the above embodiment, step 103 may include:
step 41: and closing the display screen and restarting the display screen so as to refresh the register data into the memory when the display screen is started.
In this embodiment, the electronic device is specifically a display device with a display screen, for example, a wearable device such as a VR device or an AR device, or may be a non-wearable device such as a computer with a display screen. When the register data in the register is refreshed to the memory, the data in the memory can be cleared by closing the display screen, and the display screen is restarted. When the display screen is restarted, the data in the register is read into the memory so as to support the normal work of the electronic equipment, so that the data is refreshed into the memory in a mode of closing and restarting the display screen, and the electronic equipment does not need to be restarted.
Based on the above embodiment, in this embodiment, the target data may be updated, so as to reduce the time required for manually inputting the target data, and further improve the efficiency of the eye pattern test. Referring to fig. 2, fig. 2 is a flowchart of a specific target data updating process provided in an embodiment of the present application, which specifically includes:
s201: and acquiring a data range corresponding to the register data.
It will be appreciated that each register has a corresponding range of values. For example, for the high-pass chip sxr2130, its adjustable registers of display mipi (Mobile Industry Processor Interface, i.e., display Mobile Industry Processor Interface) are 0x0ae94420 register and 0x0ae96420 register, where the range of values (i.e., data range) of the 0x0ae94420 register is 0x00 to 0x3f, and both registers need to be in this range when setting the register data in the 0x0ae94420 register by using the target data. Therefore, the data range corresponding to the acquired register data can define an update range for subsequent target data updating. Note that the present embodiment is not limited to the specific execution timing of S201, and may be executed before the target data is updated.
S202: and obtaining an eye pattern test result.
The eye test result may be a test result obtained when the eye test is performed by using the current register data, and the specific form thereof is not limited, and may be, for example, 0 or 1, or may be a fraction, for example, 60. The eye pattern test result can be divided into a pass type and a fail type, and the pass type indicates that the current register data can enable the electronic equipment to work normally and meets the requirements; if the register data fails, the electronic equipment cannot work normally by using the current register data, and the requirement is not met.
S203: and judging whether the eye pattern test result is passed or not.
It can be understood that there are various ways to determine whether the eye pattern test result passes, and the determination way may be different according to the specific form of the eye pattern test result. For example, when the eye pattern test result is 0 or 1, 1 may be determined to be passed. Or when the eye pattern test result is a score, it may be determined as passing when the score is greater than 60 minutes. If the eye pattern test result is pass, the process may proceed to step S205, and if the eye pattern test result is fail, the process may proceed to step S204.
S204: and updating the target data according to the data range, and writing the updated target data into the target file.
If the eye pattern test result is failed, it indicates that the current register data cannot enable the electronic device to work normally, so the target data can be updated according to the data range, that is, new data is selected as the target data in the target data range, and the target data is written into the target file after being updated, so that the updated target data can be read to the register through the target file. The embodiment does not limit the specific updating manner, and for example, a preset updating sequence of updating from large to small or updating from small to large may be set, data may be determined in the data range according to the preset updating sequence, and the determined data may be determined as the updated target data.
Further, in a possible implementation, the number of registers is multiple, so that when the target data is updated, only the target data corresponding to a part of the registers may be updated. For example, only the register data corresponding to one register may be updated at a time, so as to perform an eye diagram test on a combination of various register data, thereby ensuring test comprehensiveness. The S204 step may include:
step 51: and judging whether the register corresponding to the target data needs to be updated or not.
Step 52: and if the target data needs to be updated, updating the target data according to a preset updating sequence according to the data range.
Before updating the target data, it may be determined whether the corresponding register needs to be updated, for example, an update flag bit may be set to respectively specify an update state of whether each register needs to be updated. If it is determined that the target register needs to be updated, the target data can be updated according to the data range and the preset updating sequence. For example, for the high-pass platform sxr2130, the adjustable registers are the 0x0ae94420 register and the 0x0ae96420 register, where the value range (i.e., data range) of the 0x0ae94420 register is 0x00 to 0x3f. The update flag bit corresponding to the 0x0ae94420 register is 1, which indicates that the update is required, and the update flag bit corresponding to the 0x0ae96420 register is 0, which indicates that the update is not required. In this case, if the current value of the register 0x0ae94420 is 0x00 and the preset update sequence is from small to large, it may be determined that the value of the updated register is 0x01, and thus the target data may be updated by using 0x 01.
S205: and (5) presetting operation.
The embodiment does not limit the specific execution content after the eye pattern test result, that is, the specific content of the preset operation is not limited, and for example, the operation may be no operation, that is, no operation is performed, or the target data may be updated, so as to continue the eye pattern test, and further filter the optimal register data for the electronic device to operate in the optimal state.
