Fig. 2 is a schematic diagram of a system in this embodiment.
The capacitive screen in the embodiment supports interaction with an active capacitive pen, supports a transmission protocol of USI2.0, the active capacitive pen also supports the transmission protocol of USI2.0, and the capacitive pen also has a Bluetooth function, so that firmware upgrading of the capacitive pen and service data interaction with a terminal can be realized through Bluetooth.
The tablet wants to connect to the bluetooth of the capacitive pen, first it needs to know the bluetooth mac address of the pen. The specific flow is that the capacitive pen clicks the screen, because the capacitive pen can communicate with the screen, the capacitive pen can continuously send an electric signal in an on state through high-frequency pulse electric signals, when the capacitive pen clicks the screen, the capacitive pen replies a capacitive screen reply signal after receiving a point signal of the capacitive screen, the capacitive screen detects that the signal replied by the capacitive pen is equivalent to establishing a link, then the capacitive screen initiates communication for acquiring state data, the data such as the angle of the capacitive pen, the pressure value and Bluetooth mac are appointed to be acquired, and after the capacitive pen receives a request of the capacitive screen, the capacitive pen sends own Bluetooth mac address through a communication protocol between the capacitive pen and the capacitive screen.
In addition to sending bluetooth mac, the capacitive pen may send a cyclic redundancy check (Cyclic Redundancy Check, CRC) check code for the bluetooth mac address, so that after the capacitive screen receives the mac address, it is checked first whether the mac address is wrong, and if the capacitive screen is wrong, the capacitive screen may reacquire the mac address until success, and the capacitive screen may tell the capacitive pen that the bluetooth mac address is not needed to be sent again. The capacitive screen stores the mac address in the memory of the tablet, and then notifies the system application through the driver, and the application can directly link to the capacitive pen through Bluetooth after receiving the mac address, without scanning Bluetooth. The embodiment can avoid the problem that when a plurality of capacitance pens are placed beside the terminal, which is not known to be linked, and after Bluetooth is linked, firmware or other operations can be upgraded by the pens.
In order to implement the above connection procedure, in this embodiment, it is proposed to modify the communication protocol of the capacitive pen and the capacitive pen. Taking USI2.0 protocol as a standard, firstly, a communication rule, such as a data organization mode, a data transmission mode, etc., is formulated, that is, a transmission protocol is modified based on the USI protocol.
In this embodiment, the communication between the capacitive screen and the capacitive pen may use radio signals, for example, the USI2.0 protocol is adopted for the communication protocol. The control software of the capacitive screen is positioned in the driving software of the capacitive screen of the terminal, and the driving software of the capacitive screen issues a command to control the capacitive screen hardware through a bidirectional two-wire synchronous serial bus i2c bus. The software of the capacitive pen end is an independent system and is located in the central processing unit of the capacitive pen.
Firstly, modifying a screen driver, and after detecting that a capacitive pen is close to a capacitive screen to establish a link, actively initiating a request for acquiring the state of the capacitive pen by the capacitive screen, wherein the request content needs to be added with the requirement for acquiring a mac address, and the requirements are packaged into a request to be sent to the capacitive pen together. After the capacitance pen receives the request of the capacitance screen, analyzing the request content, adding the functions of analyzing the Bluetooth mac address and sending the mac address, and after the Bluetooth mac address is analyzed, the capacitance pen can package the Bluetooth mac address and the conventional data such as the pressure value, the dip angle and the like of the pen together and then send the data to the capacitance screen.
When the capacitive screen receives data, analysis of response data of the pen is increased, analysis and verification of Bluetooth mac address are increased, polynomial operation such as operation of crc8 and crc12 is performed after the mac address data are analyzed, and compared with content of a crc8 address verification code sent by the pen, if the content is consistent, communication is successful, and if the content is inconsistent, re-request is performed.
The transmission data includes a 48bit bluetooth mac address and an 8bit crc check code, stored as shown in fig. 3 below.
After the mac address is successfully acquired, a new code is needed in the driving of the capacitive screen, so that the mac address is transmitted to an upper layer application on the terminal, and the upper layer application can be directly connected to the capacitive pen through Bluetooth after the upper layer application takes the Bluetooth mac address. The mac address is transmitted to the upper layer application, and the application obtains the mac address by socket transmission or file node provided by the drive of the linux operating system, reading and change monitoring of the application. Bluetooth can be used for large data transmission. This embodiment can avoid the problem of not knowing what to link when multiple pens are placed next to the tablet, and the bluetooth link can be followed by a pen to upgrade firmware or other operations. In the above embodiment, the bluetooth mac address may be replaced by a wifi IP address, and may be directly connected to the pen through wifi after the IP address is taken. The screen and pen transmission protocol may be USI2.0, and may be any other screen and pen communication protocol, such as USI1.0 BPP WGP LPP HPP, and other wireless transmission protocols.
