S101, when terminal device initializes multiple devices under I2C bus, if it is determined that there are events under I2C bus
First device of barrier then carries out hardware reset to all devices under I2C bus.
In one embodiment of the invention, when terminal device initializes multiple devices under I2C bus, for I2C
Each device under bus, when initializing current device, if it is judged that the initialization result of current device is abnormal, then again
Initialize current device.
If it is judged that the initialization result of current device is still abnormal, then using current device as the first device, that is, when
Preceding device is faulty device.
Wherein, initialization device refers to the device for accessing the address I2C, and it is some pre-set to control device execution
Work.
For example, for the device A under I2C bus, it is assumed that setting is initialized in device A in terminal device, controller
It is C that part A, which executes operation B standard results obtained,.Device A is initialized in terminal device, if terminal device obtains
It is C1 that device A initialization, which executes operation B result obtained, can determine that device A initializes result obtained by comparing
It is inconsistent with standard results, it is determined that device A is abnormal, and controls and initialize again to device A, and obtains and initialize again
As a result, if the result is still inconsistent with standard results, it is determined that device A break down, that is, determine that device A is asked
Topic.
S102 reinitializes the second device under I2C bus, wherein all devices include the first device and the second device
Part.
That is, faulty device is not initialized in the device process under initial I2C bus again,
That is, skipping the initialization of faulty device.
For example, it is assumed that there are five devices, respectively device 1, device 2, device 3, device 4 and device under I2C bus
5, when being initialized to the device under I2C bus, if it is determined that device 3 is faulty, then again to the device under I2C bus

Row hardware reset.
In one embodiment of the invention, in terminal device according to more under initial order information initializing I2C bus
When a device, when initializing current device, if it is judged that the initialization result of current device is abnormal, then reinitializes and work as
Preceding device.
If it is judged that the initialization result of current device is still abnormal, then using current device as the first device, that is, when
Preceding device is faulty device.
Wherein, initialization device refers to the device for accessing the address I2C, and it is some pre-set to control device execution
Work.
For example, for the device A under I2C bus, it is assumed that setting is initialized in device A in terminal device, controller
It is C that part A, which executes operation B standard results obtained,.Device A is initialized in terminal device, if terminal device obtains
It is C1 that device A initialization, which executes operation B result obtained, can determine that device A initializes result obtained by comparing
It is inconsistent with standard results, it is determined that device A is abnormal, and controls and initialize again to device A, and obtains and initialize again
As a result, if the result is still inconsistent with standard results, it is determined that device A break down, that is, determine that device A is asked
Topic.
In implementing at of the invention one, the state of the device in terminal device is understood in order to facilitate user, and then conveniently
User's subsequent maintenance is determining there are when faulty first device, the relevant information of the first device is supplied to user.
Wherein, relevant information can include but is not limited to name information.
That is, determining that there are failures there are user's device when faulty device, is prompted, to facilitate user's root
It goes to repair according to prompt, for example, user can go to replace or repair after sale faulty device according to prompt.
S204 reinitializes the second device under I2C bus, wherein all devices include the first device and the second device
Part.
Specifically, the second device under I2C bus can be reinitialized according to initial order information.
For example, it is assumed that there are five devices, respectively device 1, device 2, device 3, device 4 and device under I2C bus
5, and initial order information is device 1, device 2, device 3, device 4 and device 5.It is carried out initially to the device under I2C bus
When change, successively device 1, device 2, device 3, device 4 and device 5 can be initialized according to initial order information, initial
When changing device 3, if it is determined that the initialization result of device 3 is abnormal, then initializes again to device 3, if device 3 is again
The result of initialization is still abnormal, it is determined that and device 3 is faulty, and carries out hardware reset to all devices under I2C bus, and
Device 1, device 2, device 4 and the device 5 under I2C bus can be reinitialized according to initial order information.It is reinitializing
During device 1, device 2, device 4 and device 5, if it is determined that there are failures for device 4, then by all devices under I2C into
Row hardware reset, and reinitialize according to initial order information device 1, device 2 and device 5 under I2C bus.
The initialization control method of the terminal device of the embodiment of the present invention, obtain I2C bus under multiple devices it is initial suitable
Sequence information, and successively initialize the device under I2C bus according to initial order information, if it is determined that there are faulty device,
Then under I2C bus all devices carry out hardware reset, and reinitialize under I2C bus there is no the devices of failure
Part.As a result, during reinitializing, the initialization of faulty device is skipped, effectively prevents initializing faulty
Device and the generation for leading to entire I2C abnormal conditions, so that other trouble-free devices can be used normally.
