For example, continuing to use the flowchart shown in fig. 2 as an example, the OTA application program may determine, through a user space, a current version number of the firmware currently used by the data forwarding chip 102, determine whether the current version number is the same as the version number to be upgraded, and upgrade, through a driver corresponding to the data forwarding chip 102, the firmware of the data forwarding chip 102 when the current version number is different from the version number to be upgraded.

After receiving the terminal wake-up instruction and the gravitational acceleration data acquired by the input device 200, the data forwarding chip 102 may send a terminal wake-up instruction to the framework layer of the terminal 100, and send the gravitational acceleration data to the framework layer of the terminal 100, where after receiving the terminal wake-up instruction and the gravitational acceleration data, the framework layer determines whether to wake up the terminal according to the gravitational acceleration data.

In a possible implementation manner, the processor 101 is further configured to wake up the terminal 100 if it is determined that the placement angle is within a preset angle threshold range. The preset angle threshold range may be 30 degrees to 90 degrees, for example, after the frame layer of the terminal 100 receives the gravitational acceleration data sent by the data forwarding chip 102, an included angle between the input device 200 and the terminal may be determined according to the gravitational acceleration data, and if the included angle is 0 degree, that is, if the input device 200 is attached to the screen of the terminal 100, it indicates that the terminal wake-up instruction is erroneously touched by the user, and the terminal 100 is not woken up. If the included angle is 180 degrees, that is, the input device 200 is attached to the back surface of the terminal 100, it indicates that the terminal wake-up command is erroneously touched by the user and does not wake up the terminal 100. If the included angle is any angle between 30 degrees and 90 degrees, it indicates that the terminal wake-up command is triggered by the user, and wakes up the terminal 100.

Illustratively, in a case where the user triggers the device wake-up request message by clicking a screen of the terminal 100 or triggers the device wake-up request message by a power key of the terminal 100, after receiving the device wake-up request message, the application layer of the terminal 100 may switch the I2C module and the display module to an active state through the framework layer of the terminal 100, and then notify the driver of the data forwarding chip 102 through a notification chain and trigger a wake-up interrupt of the data forwarding chip 102 to wake up the data forwarding chip 102. After the data forwarding chip 102 is woken up, a device wake-up command may be sent to the input device 200 through the data forwarding chip 102, and the input device 200 may wake up the input device 200 after receiving the device wake-up command sent by the data forwarding chip 102.

The processor 101 is further configured to send a device sleep instruction to the data forwarding chip 102 in response to a sleep request message triggered by a user;

the data forwarding chip 102 is further configured to send the device sleep instruction to the input device 200, where the device sleep instruction is used to control the input device 200 to sleep;

the processor 101 is further configured to control the data forwarding chip 102 to enter a sleep state after the input device 200 enters the sleep state.

For example, in a case where the user triggers the sleep request message by clicking a screen of the terminal 100 or triggers the sleep request message by a power key of the terminal 100, after receiving the sleep request message, an application layer of the terminal 100 may notify a driver of the data forwarding chip 102 through a pre-registered notification chain, send a device sleep instruction to the input device 200 through the data forwarding chip 102, and after receiving the device sleep instruction sent by the data forwarding chip 102, the input device 200 may control the input device 200 to enter a sleep state. Thereafter, after the input device 200 enters the sleep state, the data forwarding chip 102 may be controlled to enter the sleep state.

After the user triggers the device wake-up command through the application layer of the terminal, the framework layer may wake up the I2C module and the display module first, wake up the driver corresponding to the data forwarding chip 102 through the display module, and wake up the input device 200 through the driver.

The terminal can control the input equipment to enter the dormant state after entering the dormant state, so that the power consumption of the input equipment is saved, and the input equipment can be controlled to enter the awakening state after entering the awakening state, so that the input equipment can enter the use state in time, and the terminal can be awakened through the input equipment, so that the user experience is improved.
