Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content.
First embodiment
The flow chart of the electrostatic processes of a kind of sensor chip that Fig. 1 provides for first embodiment of the invention, the method of the present embodiment can be performed by the electrostatic treatment devices of sensor chip, this device realizes by the mode of hardware and/or software, and generally can be integrated in the terminal equipment being configured with described sensor chip.Such as, smart mobile phone or panel computer etc., do not limit this.
The method of the present embodiment specifically comprises the steps:
110, when sensor chip is in running order, read the current registrar value of marker register in described sensor chip, wherein, described marker register is the register storing setting configuration parameter.
At present, various intelligent terminals popular on the market, all there is one or more transducer, these transducers are by detecting and obtaining the physical parameters such as outer signals, light, heat and temperature, and the information being for conversion into the signal of telecommunication or other desired forms according to certain rules exports, make terminal equipment can be more and more intelligent.Wherein, the function had according to transducer, can be divided into transducer: gravity sensor, acceleration transducer, ambient light sensor, proximity transducer and gesture sensor.
In the present embodiment, described sensor chip for only having the chip of a sensor function, also can be able to be that compatibility has the chip of multiple sensor function simultaneously, not limiting this.Such as, be integrated with gesture transducer (the being called for short GES) function etc. on ambient light sensor (being called for short ALS) function, proximity transducer (being called for short PROX) function and four direction in the TMG399x sensor chip of AMS (Austrian Wei electricity company) simultaneously.
In general, there is in sensor chip multiple register, the purposes of these registers mainly comprises: store setting configuration parameter (such as, all kinds of configuration parameter during normal work or the configuration parameter etc. of Measurement Algorithm), and store real-time measurement values etc.Wherein, for storing the register value meeting real-time change in the register of real-time measurement values, then can remain constant for the register value stored in the register of setting configuration parameter.
Therefore, in the present embodiment, the mode whether changed by the register value stored in detecting sensor chip in the marker register of setting configuration parameter, judges whether this sensor chip exists electrostatic.
Wherein, when user opens a sensor function by human-computer interaction interface or operating system backstage, can trigger and produce the sensor chip open event corresponding with this sensor function, accordingly, when user closes a sensor function by human-computer interaction interface or operating system backstage, can trigger and produce the sensor chip close event corresponding with this sensor function.
In the present embodiment, by detecting the sensor chip open event and sensor chip close event in real time, can determine that whether sensor chip is in running order; Or
Also can first for sensor chip arranges job mark (such as: sensor_work_flag), this work mark can be set to different values (such as according to the sensor chip open event detected or sensor chip close event, sensor_work_flag is set to " 1 " when sensor chip open event being detected, be set to " 0 " when sensor chip close event being detected), therefore, by the mode of this work of direct-detection mark, can determine that whether sensor chip is in running order.
120, when described current registrar value is different from the standard register value prestored, reset processing is carried out to described sensor chip, to eliminate the electrostatic in described sensor chip.
In the present embodiment, need first the register value in marker register each in sensor chip to be stored as standard register value; Afterwards when sensor chip is in running order, the current registrar value reading marker register in this sensor chip and the standard register prestored are compared: if inconsistent, then determine to have electrostatic in this sensor chip, and then reset processing is carried out to described sensor chip, to eliminate the electrostatic in described sensor chip.
Wherein, the number due to marker register is generally multiple, therefore, when the current registrar value that can find a marker register in comparison process is different from the standard register value prestored, namely carries out reset processing to described sensor chip;
Consider the existence of accidental error, preferably, first after the current registrar value in whole marker register and the standard register value prestored can being compared, obtain the number of the not identical register of comparison result, when this number is greater than the threshold condition of setting, reset processing is carried out to described sensor chip.
Wherein, reset processing is carried out to described sensor chip and specifically can comprise: the whole registers in described sensor chip are all carried out reset operation, reverts to initial value.
The embodiment of the present invention is by when sensor chip is in running order, the currency being used for the marker register storing setting configuration parameter is compared with the standard register value prestored, if the numerical value according to storing in comparison result determination marker register changes, then determine that this sensor chip is subject to electrostatic influence and then the technological means of this sensor chip that resets, solve in prior art and raised by the manufacturing cost structure of electronic equipment and hardware aspect being improved to the electronic equipment reducing or solve electrostatic problem and bring, technique becomes the problems such as complexity, reduce the economic input of electronic equipment in antistatic, reduce process complexity, in addition, also can recover in time by Timeliness coverage electrostatic problem in the use procedure of electronic equipment, improve Consumer's Experience.
