According to the technical scheme, aiming at the technical problems of insufficient convenience and safety caused by inconvenient plugging and unplugging of the MiPi interface in the related art, firstly, when the camera module is plugged into the electronic equipment, a first reset pin of the MiPi interface seat, a second reset pin of the MiPi interface plug, a power supply and a ground wire form a passage, and the MiPi interface control circuit is conducted. Thus, the first reset pin at this time has current flowing through it. In other words, if the first reset pin is detected to have current passing through, it is indicated that the camera module is inserted into the electronic device, so that whether the first reset pin of the MiPi interface seat in the electronic device has a specified electrical signal can be detected. The specified electrical signal refers to an electrical signal which can be detected by a first reset pin in the MiPi interface control circuit when a current flows through the first reset pin.
Next, if the first reset pin has the specified electrical signal, it is indicated that the camera module is inserted into the electronic device, and at this time, a reset instruction is sent to the second reset pin of the MiPi interface plug in the camera module, so that the camera module can be controlled to reset, so that the camera reenters the running state.
After the camera module is reset, the electronic equipment can handshake with the camera module.
Optionally, an I2C bus may be used to handshake with the camera module, where the I2C bus is a simple, bidirectional two-wire synchronous serial bus, and may be used to transfer messages.
If the handshake is successful, the electronic equipment and the camera module are successfully connected, namely the camera module is not reversely inserted, and at the moment, the electronic equipment can normally communicate with the camera module through the MiPi protocol.
Otherwise, if the handshake fails, it indicates that the connection between the electronic device and the camera module is not successfully established, and communication cannot be performed, which is caused by reverse plug of the camera module, so that the MiPi interface can be controlled and processed by the MiPi interface control circuit under the condition that the camera module is reversely plugged, so as to solve the problem that the camera module cannot work normally due to reverse plug of the camera module.
Specifically, the MiPi interface plug of the camera module has two parallel rows of pins, with a second target pin. If the camera module is being inserted into the electronic device, the second target pin of the MiPi interface plug of the camera module is correspondingly connected with the third target pin of the MiPi interface seat of the electronic device. If the camera module is reversely inserted into the electronic device, the MiPi interface plug is turned 180 ° relative to the position where the MiPi interface plug is connected with the third target pin of the MiPi interface seat, and the first target pin is turned to the position after the MiPi interface plug is turned 180 ° instead of the original second target pin. In other words, if the camera module is reversely inserted into the electronic device, the third target pin of the MiPi interface socket is connected with the first target pin which is diagonally distributed with the second target pin in the MiPi interface plug. It will be appreciated that such back-plugging results in the electronic device not being connected to the camera module in a manner that enables efficient communication, i.e., the electronic device is not in communication with the camera module.
Therefore, the present application corrects the error condition of the third target pin connected to the first target pin to the third target pin connected to the second target pin.
Specifically, the MiPi interface control circuit is provided with a forward-reverse plug control switch, which is a single-pole double-throw switch, and has a control end and two open-close ends, wherein the control end is connected with a third target pin of the MiPi interface seat, the two open-close ends are arranged in the MiPi interface plug, one is connected with a second target pin in the MiPi interface plug, and the other is connected with a first target pin in the MiPi interface plug.
If the handshake fails, the camera module is reversely inserted into the electronic equipment, the current opening and closing end of the forward and backward insertion control switch is connected with a first target pin in the MiPi interface plug, and the non-current opening and closing end is connected with a second target pin in the MiPi interface plug. At this time, a switch control signal is generated to control the closing position of the forward and reverse plug control switch of the MiPi interface seat to be switched from the current opening and closing end to the non-current opening and closing end, that is, the original connection between the third target pin and the first target pin is disconnected, and the third target pin and the second target pin are connected, so that the actual connection relationship between the MiPi interface plug and the MiPi interface seat is consistent with that when the camera module is being plugged in the electronic device. On the basis, the electronic equipment can succeed in handshake with the camera module again.
According to the technical scheme, the insertion of the camera module is identified through the detection of the first reset pin of the MiPi interface seat in the electronic equipment, namely, the camera module is connected into the electronic equipment under the condition that the power supply is not turned off, so that the hot plug of the camera module is realized, and meanwhile, the actual connection relation between the MiPi interface plug and the MiPi interface seat is consistent with the situation that the camera module is reversely plugged into the electronic equipment through the forward and reverse plug control switch, so that the plug action is not limited by forward and reverse. In conclusion, the hot plug and the forward and backward plug of the MiPi interface between the camera module and the electronic equipment are realized, great convenience is provided for the plug of the camera module using the MiPi interface, and meanwhile, the plug safety is also improved.

Further, whether the camera module is reversely inserted or not and the MiPi interface is controlled and processed under the condition that the camera module is reversely inserted are detected through the MiPi interface control circuit, so that the problem that the camera module cannot work normally due to the reverse insertion of the camera module is solved, and the camera module and the electronic equipment are effectively docked. For a better understanding of the technical solutions of the present application, embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 shows a flow chart of a MiPi interface control method according to one embodiment of the present application.
As shown in fig. 1, a MiPi interface control method according to one embodiment of the present application includes:
step 102, detecting whether a first reset pin of a MiPi interface socket in an electronic device has a specified electrical signal.
Based on the above-mentioned structure of the MiPi interface detection circuit, when the camera module is inserted into the electronic device, the first reset pin of the MiPi interface socket, the second reset pin of the MiPi interface plug, the power supply and the ground line form a path, and the MiPi interface control circuit is turned on. Thus, the first reset pin at this time has current flowing through it. In other words, if the first reset pin is detected to have current passing through, it is indicated that the camera module is inserted into the electronic device.
The specified electrical signal refers to an electrical signal which can be detected by a first reset pin in the MiPi interface control circuit when a current flows through the first reset pin.
Step 104, if the first reset pin has the specified electrical signal, a reset instruction is generated, and the reset instruction is sent to a second reset pin of the MiPi interface plug in the camera module through the first reset pin, so that the camera module is reset.
If the first reset pin has the specified electrical signal, the camera module is inserted into the electronic equipment, at the moment, a reset instruction is sent to a second reset pin of the MiPi interface plug in the camera module, and the camera module can be controlled to reset so that the camera can reenter the running state.
And step 106, responding to the reset of the camera module and carrying out handshake with the camera module.
And step 108, if the handshake fails, generating a switch control signal to control the closing position of the positive and negative plug control switch of the MiPi interface seat to be switched from the current opening and closing end to the non-current opening and closing end through the switch control signal.
The control end of the forward and reverse plug control switch is connected with a third target pin of the MiPi interface seat, the current opening and closing end is arranged in the MiPi interface plug and connected with a first target pin in the MiPi interface plug, the non-current opening and closing end is arranged in the MiPi interface plug and connected with a second target pin in the MiPi interface plug, the first target pin and the second target pin are distributed diagonally in the MiPi interface plug, and the second target pin is an object connected with the third target pin when the camera module is effectively plugged in the electronic equipment.
In addition, if the handshake is successful, the communication is carried out with the camera module through the MiPi protocol.
After the camera module is reset, the electronic equipment can handshake with the camera module. Optionally, an I2C bus may be used to handshake with the camera module, where the I2C bus is a simple, bidirectional two-wire synchronous serial bus, and may be used to transfer messages.
If the handshake is successful, the electronic equipment and the camera module are successfully connected, namely the camera module is not reversely inserted, and at the moment, the electronic equipment can normally communicate with the camera module through the MiPi protocol.
Otherwise, if the handshake fails, it indicates that the connection between the electronic device and the camera module is not successfully established, and communication cannot be performed, which is caused by reverse plug of the camera module, so that the MiPi interface can be controlled and processed by the MiPi interface control circuit under the condition that the camera module is reversely plugged, so as to solve the problem that the camera module cannot work normally due to reverse plug of the camera module.
Specifically, the MiPi interface plug of the camera module has two parallel rows of pins, with a second target pin. If the camera module is being inserted into the electronic device, the second target pin of the MiPi interface plug of the camera module is correspondingly connected with the third target pin of the MiPi interface seat of the electronic device. If the camera module is reversely inserted into the electronic device, the MiPi interface plug is turned 180 ° relative to the position where the MiPi interface plug is connected with the third target pin of the MiPi interface seat, and the first target pin is turned to the position after the MiPi interface plug is turned 180 ° instead of the original second target pin. In other words, if the camera module is reversely inserted into the electronic device, the third target pin of the MiPi interface socket is connected with the first target pin which is diagonally distributed with the second target pin in the MiPi interface plug. It will be appreciated that such back-plugging results in the electronic device not being connected to the camera module in a manner that enables efficient communication, i.e., the electronic device is not in communication with the camera module.
In this regard, the present application may employ a MiPi interface control circuit to correct an error condition of the third target pin being connected to the first target pin to the third target pin being connected to the second target pin.
Specifically, the MiPi interface control circuit is provided with a forward-reverse plug control switch, which is a single-pole double-throw switch, and has a control end and two open-close ends, wherein the control end is connected with a third target pin of the MiPi interface seat, the two open-close ends are arranged in the MiPi interface plug, one is connected with a second target pin in the MiPi interface plug, and the other is connected with a first target pin in the MiPi interface plug.
If the handshake fails, the camera module is reversely inserted into the electronic equipment, the current opening and closing end of the forward and backward insertion control switch is connected with a first target pin in the MiPi interface plug, and the non-current opening and closing end is connected with a second target pin in the MiPi interface plug. At this time, a switch control signal is generated to control the closing position of the forward and reverse plug control switch of the MiPi interface seat to be switched from the current opening and closing end to the non-current opening and closing end, that is, the original connection between the third target pin and the first target pin is disconnected, and the third target pin and the second target pin are connected, so that the actual connection relationship between the MiPi interface plug and the MiPi interface seat is consistent with that when the camera module is being plugged in the electronic device. On the basis, the electronic equipment can succeed in handshake with the camera module again.
In addition, after the error condition that the third target pin is connected to the first target pin is corrected to be that the third target pin is connected to the second target pin, the step returns to step 102, and whether the first reset pin of the MiPi interface socket in the electronic device has the specified electrical signal is detected again, so as to restart the handshake procedure.
According to the technical scheme, the insertion of the camera module is identified through the detection of the first reset pin of the MiPi interface seat in the electronic equipment, namely, the camera module is connected into the electronic equipment under the condition that the power supply is not turned off, so that the hot plug of the camera module is realized, and meanwhile, the actual connection relation between the MiPi interface plug and the MiPi interface seat is consistent with the situation that the camera module is reversely plugged into the electronic equipment through the forward and reverse plug control switch, so that the plug action is not limited by forward and reverse. In conclusion, the hot plug and the forward and backward plug of the MiPi interface between the camera module and the electronic equipment are realized, great convenience is provided for the plug of the camera module using the MiPi interface, and meanwhile, the plug safety is also improved.
In one possible design, the pin distribution of the MiPi interface plug of the camera module is shown in table 1 below, and the pin distribution of the MiPi interface socket of the electronic device is shown in table 2 below. When the camera module is being inserted into the electronic device, the pins with the same pin serial numbers are phase-locked, for example, the pin CAM_d2P of the MiPi interface plug is the pin CAM_d2P of the MiPi interface seat when the camera module is being inserted into the electronic device.

The MiPi signals are classified into a POWER supply, a high-speed signal, and a low-speed signal, wherein pins used for the POWER supply signal include POWER and GND. Pins used for high speed signals include: the differential pair of MiPi clock signals cam_ckp, cam_ckn, and the differential pair of MiPi data signals cam_d0P, CAM _d0N, CAM _d P, CAM _d N, CAM _d2N, CAM _d2N, CAM _d P, CAM _d3n. The pins used for the low speed signal are the I2C bus signals CAM_SDA, CAM_SCL, and the module clock signal CAM_MCLK0, and the reset and detect signals CAM_RST0_DET.
According to the technical scheme, the angle distribution is carried out on each type of pins of the MiPi interface plug and the MiPi interface seat, so that when the camera module is reversely inserted on the electronic equipment, the connection states of the pins are consistent with those of the camera module when the camera module is positively inserted on the electronic equipment, and if the A12 pin GND of the MiPi interface plug is always correspondingly connected with the GND of the MiPi interface seat under the positive and negative insertion condition. Meanwhile, when the camera module is reversely inserted into the electronic equipment, the actual connection relation between the MiPi interface plug and the MiPi interface seat can be consistent with that of the camera module when the camera module is inserted into the electronic equipment only by switching the forward and reverse insertion control switch through the MiPi interface control circuit, so that the insertion and extraction actions are not limited by the forward and reverse directions.
In addition, when the camera module is reversely plugged into the electronic device, a plurality of pins cannot be consistent with the situation that the camera module is being plugged into the electronic device, and the pins are CAM_D0P, CAM _D0N, CAM _D1P, CAM _D1N, CAM _D2P, CAM _D2N, CAM _D3P, CAM _D3N, CAM _SDA, CAM_RST0_DET, CAM_MCLK0 and CAM_SCL of the MiPi interface plug respectively.
In one possible design, as shown in fig. 2, the MiPi interface control circuit, on the MiPi interface plug side of the camera module, is adjacent to cam_d P, CAM _d0n, and the two ports are connected in parallel with the butt ends of the MiPi interface socket, and then the front and back plug control switches are plugged in front and back to save the number of front and back plug control switches.
Similarly, the cam_d P, CAM _d1n is adjacent, the cam_d P, CAM _d2n is adjacent, and the cam_d P, CAM _d3n is adjacent, and all three groups of interfaces can be connected with the same positive and negative plug control switch in a manner of connecting the butt ends in parallel. And for the four groups of switches on the side of the MiPi interface seat, the same switch connection mode can be adopted.
On the basis, in connection with the method shown in fig. 1, the camera module is being inserted into the electronic device, and the switches (i.e. the positive and negative insertion control switches) 1 to 8 in fig. 2 are all closed at the first open end (i.e. the non-current open end in the embodiment shown in fig. 1), at this time, the pins cam_d0P, CAM _d0N, CAM _d1_d3d5jd2P, CAM _d2N, CAM _d3P, CAM _d3N, CAM _sda, cam_rst0_det, cam_mclk0 and cam_scl on the MiPi interface socket side of the electronic device are respectively connected with the pins cam_d0P, CAM _d0N, CAM _d1P, CAM _d1N, CAM _d2P, CAM _d2N, CAM _d3P, CAM _d3N, CAM, cam_0_det, cam_mclk0 and cam_mclk0 on the MiPi, and at this time, the electronic device performs a handshake with the camera module.
If the camera module is reversely plugged into the electronic device, the positive-negative plug control switch 1, the positive-negative plug control switch 2, the positive-negative plug control switch 3 and the positive-negative plug control switch 4 in fig. 2 are all closed at the first open-close end (i.e. the current open-close end in the embodiment shown in fig. 1), at this time, the pins cam_d0P, CAM _d0N, CAM _d P, CAM _d1N, CAM _d2P, CAM _d2N, CAM _d P, CAM _d3N, CAM _sda, cam_rst0_det, cam_mclk0 and cam_scl on the MiPi interface socket side of the electronic device are respectively docked with the pins cam_d P, CAM _d N, CAM _d P, CAM _d3N, CAM _d0_ 0P, CAM _d0N, CAM _d P, CAM _d1_ 1N, CAM _rst0_det, cam_sda, cam_scl and cam_mclk0, and the electronic device cannot be connected, and the electronic device fails to handshake with the camera module at this time.
If the handshake fails, the switch control signals control the positive and negative plug control switch 1, the positive and negative plug control switch 2, the positive and negative plug control switch 3 and the positive and negative plug control switch 4 to switch the closed position to the second open end (i.e. the non-current open end in the embodiment shown in fig. 1), so that the pins cam_d0P, CAM _d0N, CAM _d1_d1N, CAM _d2P, CAM _d2N, CAM _d3P, CAM _d3N, CAM _sda, cam_rst0_det, cam_mclk0 and cam_scl on the socket side of the MiPi interface of the electronic device are respectively connected with the pins cam_d0P, CAM _d0_3787_d1N, CAM _d2P, CAM _d2d2_d23_d3P, CAM _d3sda, cam_rst0_scl, cam_mclk0 and cam_mclk0 on the plug side of the camera module, so that the positive and negative plug of the electronic device are not connected with the socket by the positive and negative plug control switch, and the positive plug of the electronic device are limited.
Based on the pin distribution described above, in one possible design, step 102 includes: and if the first reset pin of the MiPi interface seat in the electronic equipment is grounded, the second reset pin of the MiPi interface plug in the camera module is connected with a power supply, and whether the first reset pin is in a high level is detected. Before step 102, setting a communication state of the first reset pin as an input state, so that the first reset pin and the second reset pin of the MiPi interface plug form a closed loop; if the first reset pin is detected to be the appointed electrical signal, setting the communication state of the first reset pin as an output state so as to output the reset instruction to the MiPi interface plug through the first reset pin; and under the condition of handshake failure, setting the communication state of the first reset pin as an input state so as to receive the switch control signal through the first reset pin.
Specifically, in one possible design as shown in fig. 3, the ISP motherboard serves as a Power supply, and the Power supply output may be a constant Power supply, or an intermittent output.
When no camera module is inserted, the CAM_RST0_DET is externally connected with the RD resistor and is at a low level, wherein the RD resistor takes a value between 50K and 100K ohms. When the camera module is plugged in, power can supply Power to the Rp resistor through an LDO (Low Dropout Regulator, low dropout linear voltage regulator), wherein the voltage of the Power after being reduced by the LDO is VDD, and the value of the Rp resistor is between 1K and 16.6K ohms. In addition, to ensure the accuracy of the insertion detection of the circuit to the camera module, the ratio between the RD resistor and the RP resistor is at least more than 3, and the range of the ratio can be 3-100. At this time, the RP resistor and the RD resistor form a voltage dividing circuit so that the cam_rst0_det level becomes RD/(rd+rp) ×vdd.
On the basis, after the ISP main board detects the high level on the CAM_RST0_DET, the CAM_RST0_DET is used for resetting the camera module, then handshake is carried out between the I2C bus and the camera module, if handshake is unsuccessful, a MiPi interface control circuit is used for switching the positive and negative plug control switch to the other side, and the identification process is repeated. And starting the MiPi protocol communication flow until the identification is successful.
On the basis of the pin distribution, in another possible design, step 102 includes: and if the first reset pin of the MiPi interface seat in the electronic equipment is connected with a power supply, the second reset pin of the MiPi interface plug in the camera module is grounded, and whether the first reset pin is at a low level is detected. Before the step of detecting whether a first reset pin of a MiPi interface seat has a specified electrical signal, setting a communication state of the first reset pin as an output state, so that the first reset pin and the second reset pin of the MiPi interface plug form a closed loop, and the first reset pin outputs the reset instruction; and under the condition of handshake failure, setting the communication state of the first reset pin as an input state so as to receive the switch control signal through the first reset pin.
On this basis, the circuit shown in fig. 3 is different in that when no camera module is inserted, the cam_rst0_det connection Power is at a high level, and when a camera module is inserted, the RP resistor and the RD resistor form a voltage dividing circuit so that the cam_rst0_det level becomes RD/(rd+rp) ×vdd and is at a low level. After the ISP motherboard detects the low level on the cam_rst0_det, the cam_rst0_det is reset, and then handshake is performed between the I2C bus and the camera module, if handshake is unsuccessful, the MiPi interface control circuit is used to switch the forward and reverse plug control switch to the other side, and the identification process is repeated. And starting the MiPi protocol communication flow until the identification is successful.
Based on the above technical scheme, the cam_rst0_det pin is multiplexed in the application, and the MiPi interface detection circuit is established, so that the identification of the insertion of the camera module is realized.

Step 406, generating reset success information, and feeding back the reset success information to the electronic device, so that the electronic device can handshake with the camera module in response to the reset success information.
Step 408, if the handshake fails, the closed position of the positive and negative plug control switch of the MiPi interface seat is switched from the current open-close end to the non-current open-close end in response to the switch control signal from the MiPi interface seat.
The control end of the forward and reverse plug control switch is connected with a third target pin of the MiPi interface seat, the current opening and closing end is arranged in the MiPi interface plug and connected with a first target pin in the MiPi interface plug, the non-current opening and closing end is arranged in the MiPi interface plug and connected with a second target pin in the MiPi interface plug, the first target pin and the second target pin are distributed diagonally in the MiPi interface plug, and the second target pin is an object connected with the third target pin when the camera module is effectively plugged in the electronic equipment.
