The working principle of the present embodiment is as follows: conveniently operate with, positioned at the upper left side of vehicle mounted multimedia screen,
When having object to move up and down within the front 10cm of inductor, a variety of different functions may be implemented, driving
When eyes do not have to stare at screen dusk, vehicle mounted multimedia can be operated by gesture movement.Using APDS-9906/
The instruction received is transmitted to vehicle mounted multimedia and is processed into corresponding operating function by PAJ7620U26 gesture sensor.It is located at
The upper left side of vehicle mounted multimedia screen will should be arrived by this and hold as long as there is object to move within the front 10cm of inductor
Row operational order cannot identify conscious or unconscious operation.
The corresponding function that user can also need to operate by the customized study of gesture, gesture function are opened navigation, are beaten
Open radio reception, open music, open bluetooth, volume+, volume-, last track, next track, mute, switching on and shutting down, mode, audio, language
The functions such as sound, homepage, return.
When GT911 operates in Receive mode, outgoing data is sent to by host CPU sends buffer area, GT911 detection
When being refreshed to transmission buffer area and there are data to need to send, Send mode is switched to from Receive mode automatically.In the mould
Under formula, starting frame signal is first sent, and detect that there is return ACK in receiving end, followed by data-signal is sent, has sent a number
According to sequence, start to detect ACK；If without ACK or not right, the byte just sent out is retransmitted, is all failed if retransmitting more than five times, can be incited somebody to action
This frame data restarts to send, until host CPU time-out exits it.After the completion of data are successfully transmitted, handled to host CPU or
After time-out, Receive mode is automatically switched to.
After enabled HotKnot proximity test function, GT911 default is operated under Approach Mode, when exiting this mould
After formula, host CPU makes GT911 enter Approach mode by issuing 0x20 or 0x21 order.Under the mode, touch control detection and
The alternate progress of the proximity test near field.Approach mode is distinct in transmitting terminal and receiving end mode: being meeting in transmitting terminal
The beacon for arranging regular agreed frequency is sent by driving induction channels, has sent the pact for detecting whether to receive receiving end return again
The beacon of set pattern rule agreed frequency determines whether that receiving end exists with this.In receiving end, Approach mode constant testing is
The no beacon for receiving the regular agreed frequency of agreement that transmitting terminal is sent returns to the beacon for arranging regular agreed frequency if detecting
Notify transmitting terminal.
At Approach mode, when discovery near field range exist can communicating terminal, can host CPU be notified in a manner of INT
To obtain state.In order to guarantee that receiving-transmitting sides reliably detect other side, after getting proximity state, must continue to keep at least
150ms detection, host CPU issue HotKnot transmission firmware again and enter Receive mode.
