With reference to Fig. 3, show the flow chart of steps of the output intent embodiment 1 of a kind of terminal signaling of the present invention, specifically can comprise the steps:
Step 301, the input signal that scanning is outside;
In embodiments of the present invention, trace routine can be increased in system start-up loading device Bootloader, to scan outside input signal.
After terminal powers on or resets, processor usually all from certain by instruction fetch the prearranged address of processor manufacturer.
Such as, its Article 1 instruction all got usually by the processor of certain model from address 0x00000000 when resetting.And usually have the solid storage device of certain type (such as: ROM, EEPROM or FLASH etc.) to be mapped on this prearranged address based on the embedded system that CPU builds.
Therefore, after terminal powers on or resets, processor first executive system start-up loading device Bootloader usually, realizes finding external input signal fast at start process.

Step 302, when scanning default input signal, sends enable control signal to described data selector, exports described second data-signal to drive described data selector by described signaling interface;
In embodiments of the present invention, user by the operation of specifying, can trigger the signal preset, and the conversion realizing signal exports.
In specific implementation, as shown in Figure 4, described default signal can comprise following at least one:
Level signal;
In this example, user can by the fixed button of lower panel middle finger, GPIO (the General Purpose Input Output that processor is connected with this button, universal input/output) interface has the change of level signal, therefore the change of level signal can be detected, and then detect that the button of specifying in panel is pressed.
Infrared signal;
In this example, user can press the button of specifying in telepilot, and telepilot sends infrared signal, and the infrared receiving terminal of processor receives infrared signal, is converted to code value, therefore can code value be detected, and then detects that the button of specifying in telepilot is pressed.
Certainly, just exemplarily, when implementing the embodiment of the present invention, can arrange other signals preset according to actual conditions, the embodiment of the present invention is not limited this above-mentioned default signal.In addition, except above-mentioned default signal, those skilled in the art can also adopt other signal preset according to actual needs, and the embodiment of the present invention is not also limited this.
Data selector can access processor, as the GPIO interface of inner single-chip microcomputer, like this can when standby or starting state, and the duty of data selector is subject to processing the control of device.
When default signal being detected, as shown in Figure 4, system start-up loading device Bootloader can drive processor to send enable control signal (Enable) to data selector.
Wherein, enable control signal can be responsible for the input and output of control signal.
In specific implementation, data selector can select corresponding second data-signal according to enable control signal, is exported by signaling interface.
It should be noted that, signaling interface generally supports the output of the second data-signal, and the second data-signal can not carry out data conversion.
Certainly, when signaling interface does not support the output of the second data-signal, the second data-signal can carry out corresponding data conversion, to obtain the support of signaling interface.After data conversion, then exported by signaling interface, the embodiment of the present invention is not limited this.
As shown in Figure 4, if the second data-signal is universal asynchronous receiving-transmitting transmitter UART signal, then process has two pins to participate in communication, one of them is input pin (RXD), for inputting (RX) data by data selector, another is output pin (TXD), for exporting (TX) data by processor to data selector, is exported by general-purpose serial bus USB interface.
Step 303, when not scanning default input signal, sends the second enable control signal to described data selector, exports described first data-signal to drive described data selector by described signaling interface.
If do not receive default signal, signaling interface uses as normal first data-signal.
It should be noted that, the second enable control signal can be low level signal.
As shown in Figure 4, if the first data-signal is general-purpose serial bus USB signal, because general-purpose serial bus USB is differential bus, data are determined by the difference of positive and negative signal, therefore, have two pins to participate in communication, one of them is transmission (I/O) data positive signal (Data Positive, DP) pin, another is the pin of transmission (I/O) data minus signal (Data Minus, DM).
Embodiment of the present invention scanning external input signal, control outside signaling interface by enable control signal and export the second inner data-signal, by multiplexing existing external interface, user directly can obtain inner signal, does not need peripheral physical interface that any change occurs, cost is low, achieve a bite multiplex, simple to operate, user is without the need to taking terminal apart, reduce technical threshold, improve the practicality of terminal.
With reference to Fig. 5, show the flow chart of steps of the output intent embodiment 2 of a kind of terminal signaling of the present invention, specifically can comprise the steps:
Step 501, receives power on signal;
In specific implementation, user can start terminal (also known as " start ") by pressing the modes such as power key, and terminal powers on, and sends power on signal to processor.
Processor is receiving power on signal, carry out power on operation, the Single Chip Microcomputer (SCM) program of processor inside starts, fixing register value can be read, this value is the storage address of storer (as Flash flash memory) Program, the program of fixed position in storer is read in internal memory, to start this program before os starting.In actual applications, those skilled in the art can choose the program of startup according to actual conditions, such as, in embedded systems, system start-up loading device Bootloader is the first paragraph code that embedded system performs after power, can run before operating system nucleus startup optimization.
For making those skilled in the art understand the embodiment of the present invention better, in embodiments of the present invention, system start-up loading device Bootloader is described as a kind of example of the program started.
The start-up course of system start-up loading device Bootloader is broadly divided into single phase (Single-Stage) and multistage (Multi-Stage) two kinds.
Usual multistage system start-up loading device Bootloader has more complicated function, better portable.The system start-up loading device Bootloader started from solid storage device adopts two benches mostly, and namely start-up course can be divided into stage1 and stage2:
Stage1 completes initiating hardware, for stage2 prepares memory headroom, and copies in internal memory by stage2, arranges storehouse, then jump to stage2.；
Step 502, the input signal that scanning is outside;
In specific implementation, can when receiving power on signal, start up system start-up loading device Bootloader, scans outside input signal by system start-up loading device Bootloader.
Step 503, when scanning default signal, sending the first enable control signal to described data selector and exporting described second data-signal to drive described data selector by described signaling interface;
Step 504, when not scanning default signal, sends the second enable control signal to described data selector, exports described first data-signal to drive described data selector by described signaling interface.
Step 505, receives by the communication port of the first data-signal or the second data-signal the signal transmitted by data selector;
Wherein, this signal is the signal of the outside inputted by described signaling interface.
In embodiments of the present invention, user can by signaling interface to processor input signal, and command processor processes.
Specifically, when input signal, data selector can select the current communication port using signal, to processor signal transmission.
Using the first data-signal if current, then can by the communication port of the first data-signal, to processor input signal.
Such as, suppose that the first data-signal is general-purpose serial bus USB signal, when not scanning first input signal of specifying, the first input signal stopping scanning outside, data selector uses general-purpose serial bus USB signal, then can by general-purpose serial bus USB to processor input signal.
Using the second data-signal if current, then can by the communication port of the second data-signal, to processor signal transmission.
Such as, suppose that the second data-signal is universal asynchronous receiving-transmitting transmitter UART signal, when scanning first input signal of specifying, data selector uses universal asynchronous receiving-transmitting transmitter UART signal, then can pass through input pin (RXD) to processor input (RX) signal.
Step 506, stops the input signal that scanning is outside.
Before load operation system, the process of the first input signal that scanning is outside in (kill) program (as system start-up loading device Bootloader) can be closed, after making os starting, the process of the outside input of scanning stops.
Now, first input signal of specifying is invalid, and the second data-signal can not export at the signaling interface with the first data-signal adaptation, and the first data-signal is exported by the signaling interface of adaptation, ensures the normal output of the first data-signal.
It should be noted that, no matter current output first data-signal or the second data-signal, the first input signal that the embodiment of the present invention can stop scanning outside in the time of presetting (as 2-3 second), while can having ensured the output of the second data-signal, ensure the normal operation of operating system.
Step 507, starts the operating system.
If program is system start-up loading device Bootloader, then can initiating hardware equipment, set up internal memory control mapping graph, thus take the software and hardware of operating system to a proper states, to get out correct environment for final call operation system kernel, the built-in application program of operating system system image or solidification is loaded in internal memory the control then turning and jump operating system place, and start the operating system operation.
The embodiment of the present invention stops detecting outside input signal, starts the operating system, ensure that the normal work of operating system and the normal output of the first data-signal.
It should be noted that, for embodiment of the method, in order to simple description, therefore it is all expressed as a series of combination of actions, but those skilled in the art should know, the embodiment of the present invention is not by the restriction of described sequence of movement, because according to the embodiment of the present invention, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in instructions all belongs to preferred embodiment, and involved action might not be that the embodiment of the present invention is necessary.
