Background

The Type-C interface is a new transmission interface that has started to be produced in recent years, and the naming primitive is a USB (Universal Serial Bus) Type-C connector.

Since the device connected by the type-c interface relates to two roles, namely sink device or source device, in order to realize the switching of different modes during the connection or disconnection of the interface, the function of plug-in or plug-out detection needs to be integrated. However, in the related art, a device plug-in and plug-out of the type-c interface connection can be detected on a Digital Signal Processor (DSP), but only the device plug-in triggers a CID plug-in interrupt, so that only a plug-in event can be detected on an Application Processor (AP) for further processing the plug-in event; when unplugging, the CID unplugging interrupt cannot be triggered, so that an Application Processor (AP) cannot know whether the device is unplugged in real time, and therefore cannot perform other processing according to the actual state.

The naming primitive USB Type-C connector of the USB Type-C interface is a firm and easy-to-use interface, supports positive and negative insertion, and is convenient and quick; meanwhile, the interface supports ultra-high rate communication functions and power output, so the TYPEC protocol is widely used, for example, an adapter of an OTG device needs to use the protocol.

As shown in FIG. 3, the Type-C interface has 12 pairs of pins distributed symmetrically, so that the positive and negative insertion can be supported without distinguishing between the positive and negative as in the conventional interface. The more important pin is the CC pin, and the CC pin is used to detect which role the connected device is in, i.e., sink device or source device. For example, a mobile phone is connected to an OTG usb disk, the mobile phone may be set to a downlink port (DFP) mode for power supply, and the usb disk may be set to an uplink port UFP mode for receiving power supply from the mobile phone. At this time, the CC pin is as shown in fig. 4. The Rd of the USB flash disk is grounded, and at the moment, if the mobile phone is in a DFP mode, namely Rp and Rd are directly connected, external sink equipment can be detected, so that the OTG USB flash disk is detected. The common connection states of the Type-C interface are shown in Table 1 (from a downstream DFP perspective).

When detecting the insertion of the Type-C interface, two modes exist. The first approach generally requires the integration of a discrete insertion detection circuit at the AP side. As shown in fig. 3, the Type-C interface has 4 GND pins that are symmetric with respect to each other, and when performing insertion detection, it is necessary to use one GND pin connected to a comparator for insertion detection. When a device (whether a source device or a sink device) is connected through a Type-C interface, the output of the comparator will pull down one GPIO (General-purpose input/output), at this time, the software will trigger an interrupt (the GPIO level will trigger an interrupt from high to low or from low to high), and then the mode of the connection interface is set to be a DRP mode, and then device detection is started. However, the above method requires additional hardware circuits such as a comparator for insertion detection, which may increase the circuit board area required for the terminal device and the cost of the terminal device.

In another approach, an integrated insertion detection CID (charger input detection) scheme is typically used, and when a device is inserted, TYPEC _ MODE is set to DRP MODE, and when the device is removed, TYPEC _ MODE is reset to SINK MODE. However, in the CID scheme, when performing insertion detection, the DSP) can detect that the device connected to the type-c interface is inserted or removed, but only the device is inserted to trigger CID insertion interruption, so that only an insertion event can be detected on an Application Processor (AP) and then the insertion event is processed; when unplugging, the CID unplugging interrupt cannot be triggered, so that an Application Processor (AP) cannot know whether the device is unplugged in real time, and therefore cannot perform other processing according to the actual state.

Specifically, the principle of the CID scheme is the same as that of a discrete insertion detection circuit through GPIO detection, except that hardware detection logic is integrated into a chip, a hardware comparator is arranged inside the chip, when a USB wire is inserted, the output level of the comparator inside the chip becomes high and is mapped to a CID hardware state flag, the CID hardware state flag indicates insertion, the CID hardware state flag indicates extraction, the inserted USB wire certainly triggers CID insertion interruption, and the AP receives the interruption and then processes the interruption; and the CID hardware state mark is configured as a pull-out mark when the device is pulled out, but the CID pull-out interruption is not triggered to inform the AP to process, so that the AP cannot know whether the device is pulled out or not in real time.

Based on one or more of the above problems, the present exemplary embodiment provides a device unplugging reporting method. The device unplugging reporting method may be applied to the server 105 configured with the type-c interface, and may also be applied to one or more of the

terminal devices

101, 102, and 103 configured with the type-c interface, which is not particularly limited in this exemplary embodiment. Referring to fig. 5, the method for reporting pulling-out of a device may include the following steps S510 to S530:

in step S510, in response to the charger input of the terminal device detecting the CID insertion interrupt, a timer is started.

In an exemplary embodiment, when a USB line is inserted, the output level of the comparator inside the chip becomes high and is mapped to the CID hardware status flag, so that the CID hardware status flag is the insertion flag. The AP starts timing in response to the CID insertion interrupt. When timing, forward timing can be adopted, namely, timing is started from 0; it is also possible to use reverse timing, i.e. counting down from the time it is desired to count.

In step S520, when the timed duration reaches the preset duration, the CID hardware status flag and the CID software status flag are read.

In an exemplary embodiment, at the time of timing, when the timing duration reaches a preset duration, the CID hardware status flag and the CID software status flag are read. The CID hardware state mark is a mark for marking a DSP state, specifically, a state mark performed by the DSP according to an electrical signal of the interface. The value of the status flag is typically stored in the CID register, so the flag may be the corresponding value in the CID register; the CID software state mark is a mark for marking an AP state, and specifically, is a state mark for marking whether an AP end-to-interface modified by a reported CID insertion interrupt or CID extraction interrupt is actually inserted by the AP end. The flag is generally denoted CID-status, and thus may be a value of CID-status. Further, the CID hardware status flag and the CID software status flag may identify the status by different flags, respectively. For example, the CID hardware status flag may indicate the status of unplugged and plugged-in by 0 and 1, respectively; as another example, the CID software status flag may indicate the detection of an insertion and the non-detection of an insertion by detect and no-detect, respectively. It should be noted that, the CID hardware status flag and the CID software status flag may adopt the same type of flag, for example, both adopt numbers; different types of markings may also be used, for example a number and a letter respectively.

Optionally, when forward timing is adopted, timing can be started from 0 until the timing duration reaches a preset duration; when the reverse timing is adopted, initial time can be set, the initial time is equal to the preset time length, then the countdown is carried out, and when the countdown is 0, the timed time length reaches the preset time length.

In step S530, when the CID hardware status flag and the CID software status flag satisfy the reporting condition, timing is stopped, and CID pulling interrupt is reported.

Wherein, the reporting condition comprises: the CID hardware status flag is a pull flag and the CID software status flag is a detect insert flag. When equipment such as a USB line is inserted into the type-c interface, the output level of a comparator in the chip becomes high and is mapped to the CID hardware state mark, so that the CID hardware state mark is an insertion mark; meanwhile, when a device such as a USB line is inserted, CID insertion interruption is triggered, and after the CID insertion interruption is received by the AP, the CID insertion interruption is processed. During processing, the CID software state mark is configured as an insertion mark; on this basis, when a device such as a USB cable is pulled out from the type-c interface, the CID hardware status flag is configured as a pull-out flag. At this time, although the device is unplugged, the CID software status flag remains the plug-in flag since the CID unplugging interrupt is not triggered. Therefore, the reporting condition can be set such that the CID hardware status flag is a pull-out flag, and the CID software status flag is a detection insertion flag.

By setting the timing, when the timing duration reaches the preset duration, the CID hardware state mark and the CID software state mark can be actively acquired, and whether CID extraction interruption needs to be reported or not is determined according to the CID hardware state mark and the CID software state mark, so that the AP can know whether the equipment is extracted or not in real time.

In an exemplary embodiment, when the CID hardware state flag and the CID software state flag do not satisfy the reporting condition, it indicates that the devices such as the USB cable and the like are not pulled out from the type-c interface, so that the timing can be reset, and the timing is restarted, so that after the timing duration reaches the preset duration again, the CID hardware state flag and the CID software state flag are read again, and then whether to report the CID pull-out interrupt is determined again according to the CID hardware state flag and the CID software state flag.

When the reporting condition is not met, resetting the timing duration and restarting the timing, and when the timing duration reaches the preset duration, re-reading the CID hardware state mark and the CID software state mark to realize the process of polling the CID hardware state mark and the CID software state mark for multiple times, and further determining whether the reporting condition is met or not and whether the CID pulling interrupt is reported or not according to the CID hardware state mark and the CID software state mark obtained every time.

In an exemplary embodiment, after detecting that the type-c interface pull-out interrupt trigger or the charging driving function ends and reporting the CID insertion interrupt, the CID hardware status flag and the status flag of the CC pin of the type-c interface may be read, and when the CID hardware status flag and the status of the CC pin satisfy the stop condition, the timing may be stopped. Specifically, for the type-c interface interrupt, the type-c interface interrupt is triggered later than the CID interrupt; meanwhile, in the case of only inserting a line, it is also possible that the type-c interface interrupt is not generated (for example, the USB line is inserted without any pull-up and pull-down, and the insertion is the same as the case of not inserting), and therefore, for the case of triggering the type-c interface insertion interrupt, it is possible to determine whether the state of pull-out occurs directly depending on the type-c interface pull-out interrupt. Therefore, when the CID hardware status flag and the status of the CC pin satisfy the stop condition, the polling process by timing may be stopped; the case of the end of the charging driving function is similar to the case of the type-c interface interruption, and the polling process by the timing can also be stopped directly by the CID hardware status flag and the state of the CC pin.

Wherein the stop condition may include: the CID hardware state mark is an insertion mark and the state mark of the CC foot is a pulling mark, or the CID hardware state mark is a pulling mark and the state mark of the CC foot is a pulling mark. It should be noted that, when the CID hardware status flag is an insertion flag and the status flag of the CC pin is a pull-out flag, it indicates insertion, and when there is a type-c interface interrupt for insertion interruption, there is certainly a corresponding pull-out interruption, so that it can be determined whether to report the CID pull-out interruption according to the pull-out interruption; when the CID hardware state mark is the pull-out mark and the state mark of the CC pin is the pull-out mark, the physical pull-out state can be determined, so that the CID pull-out interruption needing to be reported can be directly determined according to the physical pull-out state. In both cases, therefore, the timing can be stopped without polling relying on timing.

Further, after the timing is stopped, when the CID hardware status flag is a pulling flag, the CID pulling interrupt may be reported, so that the AP may know whether the device is pulled in real time.

It should be added that, no matter what kind of CID pulling interrupt reported above is received by the AP, in response to the CID pulling interrupt, the AP may configure the CID software status flag as undetected from the insertion flag.

In addition, when the connection mode of the type-c interface is in a dual role port (DPR), a periodic square wave is output on the CC pin of the type-c interface. Such periodic square wave output may cause system power consumption of the device in which the type-c interface is located; meanwhile, in the case that the type-c interface is electrified for a long time, interface corrosion, electric leakage and the like may occur. Therefore, no matter which of the above situations is reported, when the AP receives the CID pulling interrupt, in response to the CID pulling interrupt, the AP may send a control instruction to adjust the connection mode of the type-c interface to an uplink port mode (UFP), so as to avoid that the connection mode of the type-c interface is still in a DRP mode when no device is connected, thereby avoiding the problems of power consumption, leakage, corrosion, and the like caused by the periodic square wave output by the type-c interface.

In an exemplary embodiment, when the terminal device configured with the type-c interface includes the OTG function, it may also be determined whether the connection mode of the type-c interface needs to be adjusted according to an OTG switch corresponding to the OTG function. Optionally, no matter which of the CID pulling-out interrupts reported by the AP receives, in response to the CID pulling-out interrupt, the AP may read the state of the OTG switch, and then determine whether the connection mode of the type-c interface needs to be adjusted according to the state of the OTG switch. When the OTG switch is in a closed state, the connection mode of the type-c interface is adjusted to UFP; when the OTG switch is in an on state, the connection mode of the type-c interface is kept to be DPR.

In an exemplary embodiment, when the terminal device configured with the type-c interface comprises the anti-burning function, the CID hardware state flag can be read again, when the CID hardware state flag is the insertion flag, the connection mode of the type-c interface is acquired, and when the connection mode of the type-c interface is the non-dual-role port mode, the connection mode of the type-c interface is adjusted to the dual-role port mode; and when the CID hardware state mark is the pull-out mark, acquiring the state of the burning-prevention function, and when the burning-prevention function is started, closing the burning-prevention function.

Referring to fig. 6 to 7, a terminal device with an OTG function and a burn-out prevention function and configured with a type-c interface is taken as an example, and a preset time is 10s, so as to explain in detail a technical solution of an embodiment of the present disclosure:

referring to fig. 6, it is assumed that the CID hardware status flag includes 0 and 1, indicating the unplugged and plugged-in states, respectively; the CID software status flag includes d and nd indicating the status of detected insertion and undetected insertion, respectively; the status flags of the CC pin include 0 and 1, indicating the unplugged and plugged-in status, respectively.

Referring to fig. 7, in step S701, a connection line is inserted into a type-c interface;

step S703 of triggering CID insertion interruption;

step S705, judging whether the AP is ready;

step S707, when the AP is not ready, after waiting for the AP to be ready, processing the CID insertion interruption;

step S709, when the AP is ready, reading and judging whether the CID hardware state flag is 1;

step S711, when the CID hardware mark is 1, starting 10S timing;

step S713, the CID software flag is set to d;

step S715, reporting CID insertion interruption to the AP, and setting the connection mode of the type-c interface as DRP.

When various connection lines are inserted, a CID insertion interrupt is triggered first, and in a function of processing the CID insertion interrupt, it is determined whether or not the AP is ready. This is because the DSP sends a message to the AP via the GLINK, and the AP is not ready to further process the message. If the AP is not ready, the CID insertion interrupt function cannot continue to process, and the AP needs to wait for the preparation and the processing. Under the condition that the AP is prepared, reading the state of the CID, wherein the read state of the CID is equal to 1 to indicate insertion, and at the moment, the 10s timing needs to be reset and the timing needs to be restarted no matter the memory before timing does not exist, and the CID software state mark is set as d; meanwhile, the AP is sent a message to inform that the insertion/extraction state of the AP is changed, the AP is required to actively read and perform corresponding actions, and finally, the connection mode of the type-c interface is set as DRP

Step 717, judging whether to trigger the type-c interface insertion interruption;

step S719, when the charging driver function probe function is finished and the CID hardware state is marked as 1, setting the CID software state as d, and reporting CID insertion interruption to the AP;

step S721, after triggering the type-c interface insertion interruption or reporting the CID insertion event to the AP, reading the CID hardware state mark and the state mark of the CC pin of the type-c interface;

step S723, judging whether the CID hardware state mark and the state mark of the CC pin meet the stop condition;

step S725, when the CID hardware state mark and the state mark of the CC pin meet the stop condition, stopping timing for 10S;

step S727, judging whether the CID hardware state flag is 0 when the timing is stopped for 10S or the timing is finished for 10S;

step S729, when the CID hardware status flag is 0, reading and judging whether the CID software status flag is d;

step S731, when the CID software label is d, reporting CID pulling interruption, and configuring the CID software label as nd;

step S733, judging whether the OTG switch is turned on or not when the CID hardware state is marked as 0;

step S735, when the OTG switch is in the close state, the connection mode of the type-c interface is adjusted to the uplink port mode;

in step 737, when the CID hardware state is marked as 1 or the OTG switch is in the on state, the connection mode of the type-c interface is maintained as the dual-role port mode.

It should be noted that the triggering of type-c interrupt is later than the triggering of CID interrupt, and when only the line is plugged in, there is a possibility that type-c interrupt will not occur, for example, the USB line is a USB line without any pull-up and pull-down, in which case the detection of pull-out can only depend on polling after 10s timing is over; if there is type-c interruption, then the type-c interruption can be used to judge whether to be pulled out or not in time.

Specifically, when detecting type-c interruption, reading a CID hardware state mark and a CC pin state mark of a type-c interface, if the CID hardware state mark is 1 and the state mark of the CC pin is 0, indicating insertion, and turning off a 10s timer for opening the CID insertion interruption at the moment, wherein the type-c extraction interruption is determined to exist because the type-c insertion interruption is determined to exist, and whether physical extraction is performed or not is processed in the type-c extraction interruption; meanwhile, when the CID hardware status is marked as 0 and the CC pin status is marked as 0, it indicates that the physical device is actually unplugged, and the timing needs to be stopped for 10 s.

Then, when the hardware status of the CID is marked as 1, the connection mode of the type-c interface needs to be kept as the DRP; when the CID hardware status flag is 0, it needs to be judged whether the current OTG switch is turned on, and if not, it needs to set the connection mode of the type-c interface as UFP, and at the same time, it judges whether the current CID software status flag is the detected connection flag, if so, it needs to report the status change to AP, and set the CID software status flag as nd, indicating that the device has been pulled out.

In addition, when the probe function of the AP running out, the prepared message of the AP is sent to the DSP through the GLINK, which is performed before the mobile phone is turned on, that is, the initialization of the power-on system is performed once. The CID hardware status flag is also read, which when it is 1 indicates that the device is inserted, the connection mode of the type-c interface is DRP, and the CID software status flag is d, and the AP is notified that the device is inserted. Then, when the type-c interrupt is triggered, whether to stop timing or to report can be determined by the CID hardware status flag and the CC pin status flag of the type-c interface.

In summary, in the present exemplary embodiment, a solution is devised to solve the problem that the plug-in detection is performed based on the CID and the unplugging thereof does not trigger the software interrupt. The scheme can avoid the problem that the CID does not trigger the software extraction interruption, and ensures the function and the power consumption within a controllable range.
