the virtual touch rear-end driving module acquires coordinate position information from the touch driving module, writes the coordinate position information in a preset buffer, generates touch interruption and sends the touch interruption to the second chip;
the virtual touch front-end driving module processes touch interruption received by the second chip and acquires the coordinate position information from the buffer through the second chip when responding to the touch interruption;
the second processing system responds to the coordinate location information by:
and when the coordinate position information belongs to a corresponding second touch area, the virtual touch front-end driving module reports the coordinate position information to the second application layer, so that the second application layer executes preset operation corresponding to the coordinate position information.
9. The manipulation method according to claim 7 or 8, wherein the first chip receives a touch interrupt sent by the touch chip through a GPIO interface, and the first chip acquires the coordinate position information from the touch chip through an I2C bus.
10. The control method according to claim 8, wherein the second chip receives the touch interrupt sent by the virtual touch back-end driver module through a GPIO interface, and the second chip obtains the coordinate position information from the buffer through an SPI bus.
