Abstract

The invention discloses a control method based on USB touch. The method comprises the following steps: 101, carrying out touch acquisition, taking a standard HID interface protocol, and using a USB standard on a hardware interface so as to be capable of realizing access of various Touch devices; and 102, carrying out touch control, and controlling USB secondary equipment through Touch equipment. By the method implemented by the invention, a Touch event is transferred into a recognizable USB signal, the secondary equipment can be controlled by the Touch equipment, and demands of people and application of an extended USB interface are met.

Description

technical field [0001] The invention relates to the technical field of communication interfaces, in particular to a method for realizing USB device control through a USB touch event. Background technique [0002] The back control based on USB touch is a kind of master device reads the USB touch event, the master device analyzes the processing flow of the event, and then distributes it to another slave device, so that one touch device can control two slave devices at the same time, and it is convenient and fast processing events. [0003] The typical application is to combine with HDMI IN input source, the master device has an HDMI IN interface and USBdevice interface, so that the connected slave device can be displayed and controlled. [0004] USB device is currently the most widely used interface device with strong versatility. However, there is no way to convert the Touch event into a recognizable USB signal through the USB interface to control the slave device connected...
