Fig. 2 is a kind of flow chart of the touch chip crash handling method shown according to another exemplary embodiment, the touching
It controls chip failure processing method to be applied in the terminal comprising touch screen, which includes touch chip, and touch chip includes
Digital circuit and analog circuit, as shown in Fig. 2, the touch chip crash handling method includes the following steps.
In step 201, the running parameter of touch chip is obtained every predetermined period, which is that digital circuit is every
Every the capacitance that predetermined period is obtained from each capacitance that analog circuit is sampled.
For capacitive touch screen, when user executes operation not on touch panel, analog circuit can sample to obtain the
One capacitance, the first capacitor value are greater than capacitor lower limit value；When user executes operation on touch panel, due to the hand of user
Refer to and generate coupled capacitor between touch panel, therefore, the capacitance of touch screen can change, and analog circuit can sample to obtain
Second capacitance, the second capacitance is greater than first capacitor value, and is less than capacitor upper limit value.According to above-mentioned touch-control principle, core is simulated
Piece can be spaced at predetermined time intervals and sample to the capacitance of touch screen, and be determined whether according to the capacitance that sampling obtains
There is the operation for acting on touch screen.Wherein, the duration of predetermined time interval is more than or equal to the duration of predetermined period.
When analog circuit failure, analog circuit cannot sample capacitance, or, the capacitance of analog sampling circuit can go out
Therefore mistake can be detected by obtaining capacitance to analog sampling circuit and determine whether analog circuit fails.
In the present embodiment, touch chip includes timer and digital circuit, digital circuit can under the control of a timer,
The capacitance that analog sampling circuit obtains is obtained every predetermined period, then executes step 202.
In step 202, detect whether capacitance belongs to predetermined interval by digital circuit.
Predetermined interval is section composed by capacitance when touch screen is in normal condition.Wherein, predetermined interval is most
Small value can be there is no first capacitor value when operation on touch panel, and the maximum value of predetermined interval can be on touch panel
Deposit the second capacitance in operation.
In step 203, when capacitance is not belonging to predetermined interval, determine that touch chip fails by digital circuit.
When capacitance is not belonging to predetermined interval, determine that the analog circuit fails, so that it is determined that touch chip fails；Work as electricity
When capacitance belongs to predetermined interval, determines that the analog circuit is effective, continue to execute step 201.
In step 204, when detecting touch chip failure according to running parameter, by digital circuit to analog circuit
It is resetted.
When determining analog circuit failure, entire touch chip can be resetted.Since it is only necessary to touch-control core
Piece is resetted, without restarting terminal, it is possible to reduce is resetted the time consumed by touch chip, be can be improved to touch-control core
The reset efficiency of piece.Alternatively,
Since the working power of digital circuit is digital power, that is, digital circuit and analog circuit in touch chip
Working power is different, therefore, when determining analog circuit failure, can also execute power-off again to analog circuit by digital circuit

Every the heartbeat signal that predetermined period is sent to processing unit.
When digital circuit failure, since the analog circuit in touch chip can not monitor digital circuit, therefore, it is necessary to
Detect whether digital circuit fails by the processing unit in terminal.
In the present embodiment, when digital circuit is effective, digital circuit needs to send the heart to processing unit every predetermined period
Jump signal；When digital circuit failure, digital circuit sends heartbeat signal without normal direction processing unit, and therefore, processing unit can be with
According to whether it is effective to detect digital circuit to receive heartbeat signal.
In step 302, the heartbeat for receiving digital circuit transmission in scheduled time slot is detected whether through the processing unit
Signal is at the time of the processing unit last time receiving heartbeat signal at the beginning of the predetermined period, and the predetermined period
Duration is greater than the duration of predetermined period.
At the time of processing unit can recorde the last time and receive heartbeat signal, determined using the moment as start time pre-
Timing section detects whether to receive heartbeat signal in the predetermined period；When receiving heartbeat signal in the predetermined period,
Determine that digital circuit is effective；When not receiving heartbeat signal in the predetermined period, determine that digital circuit fails.
The duration of predetermined period can be equal to the duration of predetermined period.Since heartbeat signal may be deposited in transmission process
It is being delayed, when causing processing unit to be not received by heartbeat signal in predetermined period due to transmission delay, processing unit meeting
Determine digital circuit fail, so as to cause error in judgement, therefore, can be set predetermined period duration be greater than predetermined period when
It is long.For example, the duration of predetermined period can be three times of the duration of predetermined period.
In step 303, when detecting not receive heartbeat signal in scheduled time slot, touching is determined through the processing unit
Control chip failure.
In step 304, when detecting touch chip failure according to running parameter, through the processing unit to digital circuit
It is resetted, or, being resetted through the processing unit to touch chip.
When determining digital circuit failure, entire touch chip can be resetted.Since it is only necessary to touch-control core
Piece is resetted, without restarting terminal, it is possible to reduce is resetted the time consumed by touch chip, be can be improved to touch-control core
The reset efficiency of piece.Alternatively,
Since the working power of digital circuit is digital power, that is, digital circuit and analog circuit in touch chip
Working power is different, therefore, when determining digital circuit failure, can also execute power-off again to digital circuit through the processing unit
The reset to digital circuit is completed in the operation of power-up.At this point, only the digital circuit in touch chip is resetted, without
Entire touch chip is needed to be reset, solves the problems, such as that the time consumed needed for resetting entire touch chip is relatively long, reaches
Further increase the effect of the reset efficiency of touch chip.
In conclusion the touch chip crash handling method that the disclosure provides, detects whether through the processing unit predetermined
The heartbeat signal that digital circuit transmission is received in period leads to when detecting not receive heartbeat signal in scheduled time slot
It crosses processing unit and determines that touch chip fails, digital circuit is resetted through the processing unit, it can be only to touch chip
In digital circuit resetted, without resetting entire touch chip, solve consumption needed for resetting entire touch chip
Time relatively long problem, achieved the effect that the reset efficiency for further increasing touch chip.
