Embodiment 1

[0049] The embodiment of the present invention provides a device connection method, the specific process can refer to figure 1 , which may include the following steps:

[0050] Step 101, the first DRP device receives role information input by a user.

[0051] Wherein, the first DRP device is provided with role information for the user to select, the role information may include but not limited to: UFP and DFP, after the user inputs the selected role information on the first DRP device, the first DRP device receives the user The entered role information.

[0052]Taking the first DRP device as a mobile phone as an example, in the embodiment of the present invention, a visual user interface control switch can be added to the mobile phone. This switch can be a switch that includes two options, DFP and UFP, for the user to choose one of. . Normally, these two options cannot be enabled at the same time. After the user inputs the selected role information on the user interface, t...

Embodiment 2

[0070] In the embodiment of the present invention, taking the role information input by the first DRP device as UFP as an example, another device connection method is provided. For the specific process, please refer to figure 2 , which may include the following steps:

[0071] Step 201, the first DRP device receives UFP role information input by the user.

[0072] Step 202, the first DRP device configures the register, so that the pull-down resistor enters an enabled state, and the pull-up resistor enters a disabled state.

[0073] The first DRP device writes and reads the register, and sets potentials for the pull-up resistor Rp and the pull-down resistor Rd in the register. When the role information entered by the user is UFP, the first DRP configures the register to set the potential for the pull-up resistor Rp and the pull-down resistor Rd, thereby starting Rp and disabling Rd. For example, configure the register and configure the corresponding potential of Rd in the reg...

Embodiment 3

[0078] In the embodiment of the present invention, taking the role information input by the first DRP device as DFP as an example, another device connection method is provided, and its specific process can be referred to image 3 , which may include the following steps:

[0079] Step 301, the first DRP device receives the role information of the DFP input by the user.

[0080] Step 302, the first DRP device configures the register so that the pull-up resistor enters the enabled state and starts, and the pull-down resistor enters the disabled state.

[0081] The first DRP device writes and reads the register, and sets potentials for the pull-up resistor Rp and the pull-down resistor Rd in the register. When the role information entered by the user is DFP, the first DRP configuration register sets the potential for the pull-up resistor Rp and the pull-down resistor Rd, thereby starting Rp and disabling Rd, for example, configuring the register, configuring the potential corresp...

Abstract

The embodiment of the invention provides an equipment connection method and device. The method comprises the steps as follows: first double-role data port DRP equipment receives role information input by a user; the first DRP equipment configures a connection role of the first DRP equipment according to role information; and the first DRP equipment is connected with second DRP equipment through the connection role. According to the equipment connection method and device, the role of the first DRP equipment can be set to be a fixed role, so that the controllability of role configuration in the DRP equipment connection process is strengthened; and the problems of power consumption of the DRP equipment with low power and shortening of the life time of the DRP equipment with low power caused by unordered random role configuration are solved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of communication, in particular to a device connection method and device. [0003] 【Background technique】 [0004] With the introduction of the Type-C interface, this new type of interface is more and more popular with users for its thinner design, faster transmission speed (up to 10Gbps) and stronger power transmission (up to 100W). focus on. [0005] In the Type-C protocol, three device roles in interconnection are proposed: Downstream Facing Port (DFP), Upstream Facing Port (UFP) and Dual Role Port (DRP) . DFP is the master device, and UFP is the slave device. During the interconnection process of two DRP devices, one of them will behave as DFP, while the other will behave as UFP. When the roles of the two devices in the interconnection are respectively When DFP and UFP are used, data transmission between them can be realized, and DFP can also charge UFP at the same time. [0006] When...
