An embodiment of the invention provides a method for controlling a light sensing module, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the method for controlling the light sensing module.
In this embodiment, the method for controlling the light sensing module includes the following steps:
step S10: and when the equipment is detected to be started, matching the light sensing modules to obtain the equipment number information of the light sensing modules.
It should be noted that the execution subject of this embodiment is a processor or other information processing apparatus on a display device, and may be any display device, including but not limited to: the present invention is not limited to this, and the present invention may be implemented in a main chip, a processor, an onboard computer, etc. of a television, a display, a projector, etc., or other devices capable of implementing the functions.
It should be understood that, currently, light sensing modules of the same model are basically configured on a display device, but since only one light sensing module of the same model is configured, no substitute is needed, which is troublesome, and thus, not only the time for mass production and marketing of products is affected, but also the problem of solving the light sensing modules through after-sale processing is affected. And normally, the damaged light sensing module can pull the I2C bus to be dead, so that the damaged light sensing module causes the problem of slow startup. The scheme of the embodiment can automatically detect whether the light sensing module is abnormal or not when the equipment is started, and can configure the bus and each signal line of the light sensing module to a specified transmission mode when the light sensing module is abnormal. And completing reading operation on the equipment light sensing module in the appointed transmission mode, and recovering the equipment light sensing module from a deadlock state to be normal, so that the bus is prevented from being dead due to abnormal damage of the light sensing module. By the mode, the light sensation modules of different types can be carried on the display equipment and are self-adaptively matched when the display equipment is started, and the applicability of the light sensation modules on the display equipment is improved. And when the light sensing module is abnormal, the bus and each signal line can be automatically configured and normal starting can be completed, so that the starting is prevented from being influenced by the abnormality of the single light sensing module.
In a specific implementation, when it is detected that the device is started, it is first detected whether the light sensing module configured inside the device is abnormal, and the device may be any display device, which is not limited in this embodiment. The detection of the device boot is that the device is powered on and the main processor begins to operate.
It should be noted that the light sensing module in this embodiment may be any type of light sensing module of any brand, and may be different types of light sensing modules.
It should be understood that, when the device startup is detected, the process of matching each light-sensing module is started first, that is, the device number information corresponding to the device information of each light-sensing module is determined.
Further, in order to obtain the device number information of each photo sensing module, the step S30 includes: when the starting of the equipment is detected, the information of the supporting light sensing device is obtained; generating a device address configuration strategy according to the information of the light sensing supporting device; and matching the light sensing modules according to the device address configuration strategy to obtain the equipment number information of each light sensing module.
In a specific implementation, the information of the supported light-sensing devices refers to the device information of the light-sensing module devices supported by the current display device, which includes the device address, the function register address, the register address length, the data length, and the like of each supported light-sensing module.
It should be noted that, in the device address configuration policy generated according to the information of the light-sensing-supporting device, the device address configuration policy refers to an address configuration policy required for matching between each light-sensing module installed on the device and the light-sensing module supported by the device, where matching of the light-sensing modules is implemented by configuring different addresses for verification.
It should be understood that, matching each photo sensing module according to the device address configuration policy to obtain the device number information of each photo sensing module means: and executing a device address configuration strategy on each light sensing module, and verifying signals through I2C, thereby determining the equipment number information corresponding to each light sensing module.
By the method, the matching of the information of the supporting light sensing devices of all the light sensing modules supported by the display equipment is realized, so that the equipment number information of each light sensing module is obtained.
Further, in order to determine how to perform matching, matching each light sensing module according to the device address configuration policy to obtain the device number information of each light sensing module, including: determining a device address configuration sequence according to the device address configuration strategy; obtaining module device information of each light sensing module; determining an equipment number comparison table of each light sensing module according to the module device information; and matching the light sensing modules according to the device address configuration sequence and the equipment number comparison table to obtain the equipment number information of each light sensing module.
In a specific implementation, determining a device address configuration sequence according to the device address configuration policy refers to: the optical sensing device module is connected to the I2C channel of the host through hardware, and generally has multiple I2C channels. The device address configuration sequence is set as: firstly, configuring the address of a light sensing device in the equipment as the address of the light sensing module 1, writing data through I2C, reading back the ID of the light sensing module equipment through I2C after writing successfully, and if the read ID of the light sensing module equipment is the same as that of the light sensing module 1, considering that the light sensing module 1 is successfully matched and identified, and then the light sensing module 1 cannot be matched with other light sensing modules; if the light sensing module 1 is not successfully identified, the light sensing module 2 is continuously identified, if the light sensing module 2 is successfully identified, other light sensing modules cannot be matched, otherwise, the light sensing module 3 is continuously identified, and the like is repeated until the matching is successful.
It should be noted that obtaining module device information of each light-sensing module refers to: and obtaining module device information of each light sensing module, wherein the module device information comprises an equipment device address, a function register address, a register address length, a data length and the like. The module device information may be obtained by querying the datashort of the optical sensing device module. The device address of the light sensing module comprises a read address and a write address.
It should be understood that determining the device number look-up table of each photo-sensing module according to the module device information means: and establishing and determining a corresponding comparison relation table of the equipment of each light sensing module and the equipment ID number according to the module device information.
In specific implementation, matching each light sensing module according to the device address configuration sequence and the equipment number comparison table to obtain the equipment number information of each light sensing module refers to: and matching the light sensing modules according to the device address configuration sequence and the equipment comparison table, so as to determine the equipment number information of each light sensing module.
Through the mode, accurate matching and determination of the equipment number information of each light sensing module are achieved, and therefore the light sensing modules can be started normally and controlled to work normally subsequently.
Step S20: and configuring each light sensing module according to the equipment number information so as to start and work each light sensing module and detect whether each light sensing module in the equipment is abnormal or not.
It should be noted that, after the device number information is determined, the device address corresponding to the device number information of each light sensing module is correctly configured, so that each light sensing module can be driven to normally operate from the bus.
Further, in order to detect whether there is an abnormality in the photo sensing module, step S10 includes: acquiring bus information; configuring a data signal line into a general input mode according to the bus information, transmitting a working signal through the data signal line in the general input mode, and detecting the signal level of the working signal on the data signal line; and determining whether the light sensing module is abnormal or not according to the detected signal level of the data signal line.
It should be understood that, for the problem that all the light sensing modules supported by the television damage the I2C bus and are dead, which results in slow start-up, the hardware amount is an I2C waveform, and the I2C bus has SDA and SCL signals, and when the light sensing modules supported by the television are damaged, the SDA signal of the I2C bus is pulled low, which results in slow start-up. I2C is a multi-master multi-slave serial synchronous communication bus consisting of two signal lines (clock signal line SCL + data signal line SDA). The specification requires that the devices accessing I2C, both the SCL clock and SDA data lines must be bi-directional open-drain, pulled to a logic high level by a pull-up resistor on the bus. Such a configuration may implement the line and (&) function. Because of this characteristic, as long as any one device on the bus pulls either SDA or SCL low, the other devices cannot pull them high, all seen as low. If there are devices that do not release the bus, then the communication on the entire bus is suspended, called an I2C bus pull-down.
In a specific implementation, the bus information refers to configuration information of each signal line on a bus to which the light sensing modules are connected.
It should be noted that configuring the data signal line to be in a general input mode according to the bus information, transmitting an operating signal through the data signal line in the general input mode, and detecting a signal level of the operating signal on the data signal line means: the SDA of the I2C for the communication between the television main chip (or other equipment or device as an execution main body) and the light sensing module is firstly configured to be in a GPIO port input mode, then a working signal is transmitted on the data signal line SDA at the moment, and then the signal level on the data signal line is detected in real time.
It should be understood that when the signal level of the data signal line is low level or is pulled low compared to the level of the signal in normal operation, it is determined that there is an abnormality in the light sensing module, otherwise, the light sensing module is in normal operation.
By the method, whether the bus is abnormal or not due to the abnormity of the light sensing module can be intuitively judged according to the signal level on the data signal line.
Step S30: and when the detection result shows that the light sensing module is abnormal, configuring the bus and each signal line of the light sensing module as a specified transmission mode.
In the specific implementation, after the light sensing module is determined to have abnormality according to the detection result, the data transmission states and modes of the bus of the light sensing module and each signal line are adjusted and tested, and finally the data transmission states and modes are adjusted to be the designated transmission modes. The signal lines include two lines, namely a data signal line SDA and a clock signal line SCL.
It should be noted that the transmission mode is designated as an I2C mode in which the SDA and SCL are configured, and the light sensing module can be adaptively matched.
Step S40: and finishing reading operation on each light sensing module in the appointed transmission mode so as to remove the deadlock state of the bus corresponding to each light sensing module.
It should be understood that, after the bus and each signal line are configured into the designated transmission mode, the read operation is performed on each light sensing module in the designated transmission mode, that is, the bus performs a read operation on each light sensing module once, so as to recover the communication state of the bus, and recover from a deadlock state, so as to prevent the bus from being locked due to an abnormality of a single or individual light sensing module, and further, the normal start of the device is affected.
In the embodiment, when the device is detected to be started, the light sensing modules are matched to obtain the device number information of each light sensing module; and configuring each light sensing module according to the equipment number information so as to start and work each light sensing module. Detecting whether a light sensing module in the equipment is abnormal or not; when the detection result indicates that the light sensing module is abnormal, configuring a bus and each signal line of the light sensing module as an appointed transmission mode; and completing reading operation on the equipment light sensing module in the appointed transmission mode, and recovering the equipment light sensing module from a deadlock state to be normal, so that the bus is prevented from being dead due to abnormal damage of the light sensing module. By the mode, the light sensation modules of different types can be carried on the display equipment and are self-adaptively matched when the display equipment is started, and the applicability of the light sensation modules on the display equipment is improved. And when the light sensing module is abnormal, the bus and each signal wire can be automatically configured and normal starting can be completed, the phenomenon that starting is influenced by the abnormality of a single light sensing module is prevented, and when the abnormality of the light sensing module occurs, the communication state of the bus is timely found and recovered from a deadlock state.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for controlling a light sensing module according to the present invention.
Based on the first embodiment, the method for controlling the light sensing module in this embodiment includes, in the step S20:
step S301: and when the detection result shows that the light sensing module is abnormal, configuring a clock signal line of the light sensing module into a general output mode, and transmitting a target clock signal through the clock signal line in the general output mode.
When it is determined that there is an abnormality in the optical sensing module, the I2C clock signal line connected to the optical sensing module is first configured in a GPIO (general purpose input/output) port output mode, and then the target clock signal is transmitted in the general output mode. Specifically, the target clock signal is a CLK clock signal whose analog output is continuous.
Further, after step S301, in order to configure the bus and the signal lines when the number of consecutive clocks is not within the cycle threshold, the method further includes: when the continuous clock quantity of the target clock signal is not in the range of the cycle threshold value, detecting the level of the data signal line to obtain a second level detection result; and configuring the bus and each signal line of the light sensing module into a designated transmission mode according to the second level detection result.
It should be understood that when the number of consecutive clocks of the target clock signal is equal to or greater than 9, that is, not within the cycle threshold range, the level of the data signal line is detected again.
In one embodiment, when the second level detection result is a low level, the SDA and SCL are directly configured as an I2C mode for adaptive matching of the light sensing module.
By the method, the bus and the signal lines can be configured to normally start and execute work of each light sensing module when the continuous clock number of the target clock signal is not in the range of the cycle threshold.
Step S302: and when the continuous clock number of the target clock signal is within a cycle threshold range and the continuous clock number changes to be at a low level, detecting the level of a data signal line of the light sensing module to obtain a first level detection result.
It should be understood that the cycle threshold range refers to a range within 1 or more and less than 9 times of CLK. When the number of consecutive clocks of the target clock signal is within a cycle threshold and the number of consecutive clocks is changed to be at a low level, the method comprises the following steps: the first level detection result is obtained if the level at which each CLK is continuously detected while outputting less than 9 consecutive CLKs changes to the low level, that is, the level on the data signal line at the time after each CLK.
Step S303: and configuring the bus and each signal line of the light sensing module into a designated transmission mode according to the first level detection result.
In a specific implementation, configuring the bus and each signal line of the photo sensing module as a designated transmission mode according to the first level detection result means: when the first level detection result is a high level, the signal states of the data signal line and the clock signal line are reconfigured, and then the bus line and the respective signal lines are configured to designate a transmission mode.
Further, in order to accurately configure the states of the bus and the signal lines, step S303 includes: when the first level detection result is that the data signal line is at a high level, configuring the data signal line into a general output mode; and under the general output mode, the signal states of the data signal line and the clock signal line are adjusted according to a level adjustment strategy, so that the bus and each signal line of the light sensing module are configured into a designated transmission mode.
It should be noted that fig. 4 is a complete flow chart of the present embodiment, wherein when the first level detection result is that the data signal line is at a high level, the data signal line is configured to the GPIO port output mode, then the SDA is set to a low level, the SCL is set to a high level, the SDA is set to a high level, and finally the SDA and SCL of the main chip are configured to the I2C mode to perform adaptive matching on the corresponding light sensing modules, so that the bus and each signal line are configured to the designated transmission mode.
By the mode, when the first evaluation detection result is that the data signal lines are at a high level, the data signal lines and the clock signal lines are sequentially adjusted through the level adjustment strategy, so that the locked state of the bus is released, and the equipment normally operates.
