Embodiment
One, use definition
Be defined in and on this airborne embedded device, input specific character and should possess following condition:
1) input character collection Φ, this character set can need according to the application of equipment customized, and such as digital 0 – 9, English alphabet A-Z, also can input Chinese character and special symbol etc.;
2) the character total amount N of character set Φ;
3) character set Φ has a null character (NUL) at least;
4) background of using according to equipment, determine can input of character string maximum length L;
5), when input of character string, the input position of character is called as character position P;
6) string length of each input is Lc;
7) character on each character position P must be a definite element in character set Φ;
8), when input of character string, character position P can move freely, 0≤P≤Lc;
9) when user finds certain character position P input error, can delete this position character;
10) after character string has been inputted, need to obtain clear and definite order announcement apparatus software systems, this character has been inputted.
Two, input process
On airborne embedded device, possess the hardware condition of three buttons, by software, arrange, complete character input.
Button Key1 refers to the acknowledgement key that character string has been inputted;
Button Key2 is that character position is selected knob, and when Key2 presses, input character position will be moved from small to large; When moving to maximum character input position, automatically jump to first character input position;
Button Key3 is character selection key, and when Key3 is pressed, the character in character set Φ occurs in alphabetical order.
This airborne embedded device should configure clear and definite character set Φ, and the character string of required input is a kind of permutation and combination of element in character set Φ.
Airborne embedded device character string input is divided into three kinds of states:
1) character string input state;
2) the deletion state of character string, i.e. dummy status;
3) abnormal input state.
The normal input state of 2.1 character strings
The first, device software is answered the maximum length of predefined character string;
The second, when interface arranges focus and enters character string input area, open the character input mode of three buttons;
The 3rd, the input position of character string acquiescence is first;
The 4th, pressing keys Key3, there is the character in character set Φ in input position, when required character occurs, stops pressing successively, and this character record is got off;
The 5th, pressing keys Key2, input position moves in order, when moving to the character position that needs input, stops pressing, and character input position is recorded;
The 6th, repeating step five and step 6, until character string has been inputted;
The 7th, pressing keys Key1, this character string of reporting system has been inputted.
Be exemplified below:
The character set Φ of agreement input be " null, Q, A, Z, W, S, X ,@, $, , *, (, you, good, western, peace) " totally 17 characters; This time need character string of input to be " QQ$ you good Xi'an ".
Utilize flight displays, when focus is set, enter after character string arranges, default character string is " _ ", shows the character input position of acquiescence;
Pressing keys Key3, often presses once, occurs a new character, occurs successively; Null → Q → A → Z → W → S → X →@→ $ → → * → (→ you → good → west → peace →) → null → Q → A → ... (circulation); While there is " Q " character, stop pressing;
Then pressing keys Key2, enters second character input position once;
Then, pressing keys Key3, completes the input of second " Q " according to aforementioned manner again;
So repeatedly sequentially pressing keys Key3, pressing keys Key2, until display string " QQ$ you good Xi'an ";
Finally, pressing keys Key1, completes character string input, and flight displays interface focus jumps to other region.
2.2 character strings are deleted state
The first, when interface arranges focus and enters character string input area, open the character input mode of button, knob;
The second, the input position of character string acquiescence is first;
The 3rd, pressing keys Key3, there is the character in character set Φ in input position, when required null character (NUL) occurs, stops pressing successively, shows that this is recorded as sky;
The 4th, pressing keys Key2, input position moves in order, when moving to the character position that needs deletion, stops pressing, and null character (NUL) input position is recorded;
The 5th, repeating step five and step 6, until null character string has been inputted;
The 6th, pressing keys Key1, this character string of reporting system has been inputted; When all characters are sky, this character string is empty, and character string is by deleted.
The abnormal input state of 2.3 character string
Abnormal input state has two kinds:
1), when entering input state, any character is not input all, presses acknowledgement key Key1, completes input; Now, character string is empty, while exiting, and delete character string;
2), after entering input state, user may press acknowledgement key Key1 never again due to a variety of causes; Now interface intersection point will be locked in character string input position, cannot exit; Now, a software timer should be set, when interface focus is during in character string input state, within a definite time, button key3 and button Key2 are not operated by user, and character string input state will exit automatically.Once button key3 or Key2 action, software timer automatic clear.
