Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with embodiment for explanation, and mode of the present utility model includes
But it is not limited only to following examples.
As shown in Figure 1, 2, the utility model is mainly used in checking the correctness of order of strokes observed in calligraphy character library that its function is continuously to show
The order of strokes observed in calligraphy of 3755 Chinese characters of first class word-base of the national standard.The utility model include AT89C51 single-chip microcomputers, key-press module, memory, four
Block 74HC595 chips and by the one 8 × 8th lattice module, the 28 × 8th lattice module, the 38 × 8th lattice module and the 4th 8
16 × 16 dot matrix screens that × 8 lattice modules are constituted.Described AT89C51 single-chip microcomputers pin 18,19 connects with a crystal oscillating circuit simultaneously
Connect, and AT89C51 single-chip microcomputers pin 9 is also connected with a reset circuit(Crystal oscillating circuit and reset circuit are not drawn in fig 2
Go out).
The pin 11 of all 74HC595 chips is all connected with the pin 11 of AT89C51 single-chip microcomputers, all 74HC595 chips
Pin 12 is all connected with the pin 12 of AT89C51 single-chip microcomputers, meanwhile, the pin 13 of all 74HC595 chips is grounded, and wherein
The pin 14 of one piece of 74HC595 chip is also connected with the pin 10 of AT89C51 single-chip microcomputers.Four pieces of 74HC595 switch to serial data
32 ranks control lines are formed after parallel data.
16 × 16 dot matrix screens are actually the LED matrix of 16 × 16, row(The negative terminal of LED)For scanning end, OK
(The anode of LED)Data input pin, as shown in Fig. 2 in figure, L1-L16 is scanning end, and H1-H16 is data terminal, 74HC595 cores
Piece is as follows with the annexation of 16 × 16 dot matrix screens:
The pin 1~7,9,15 of one of 74HC595 chips simultaneously with the one 8 × 8th lattice module and the 2nd 8 × 8 point
The anode connection of array module;
The pin 1~7,9,15 of second piece of 74HC595 chip simultaneously with the 38 × 8th lattice module and the 48 × 8th dot matrix
The anode connection of module;
The pin 1~7,9,15 of the 3rd piece of 74HC595 chip simultaneously with the one 8 × 8th lattice module and the 38 × 8th dot matrix
The negative terminal connection of module;
The pin 1~7,9,15 of the 4th piece of 74HC595 chip simultaneously with the 28 × 8th lattice module and the 48 × 8th dot matrix
The negative terminal connection of module.
The key-press module connects the P1 ports of AT89C51 single-chip microcomputers(Accompanying drawing 2 is not drawn into), three buttons are which is provided with,
It is respectively playback, upper one and time-out, continuation, checks and record to facilitate.
The memory connects the pin 29 of AT89C51 single-chip microcomputers(Accompanying drawing 2 is not drawn into), in the present embodiment, memory is adopted
FLASH MEMORY are used, model is K9F1208U0M-YCB0, this is a kind of NAND FLASH.NOR FLASH can also be used,
Because order of strokes observed in calligraphy word-base data amount is simultaneously less, about 270K or so.
The utility model can be according to the sequential write of Chinese character, it would be desirable to the coordinate of the point lighted on 16 × 16 dot matrix screens,
Then sequentially arrange, then using 0 as end mark, just constitute the order of strokes observed in calligraphy dot matrix of a Chinese character.By GB one-level
The order of strokes observed in calligraphy dot matrix of 3755 Chinese characters of character library is combined, and is exactly the order of strokes observed in calligraphy character library alleged by the utility model, finally deposited to
In memory.When using, being input into using key-press module needs the Chinese character of demonstration, and 16 × 16 dot matrix screens will be according to the book of the Chinese character
Write order and light corresponding coordinate one by one, be finally completed the complete demonstration of the Chinese character.And during demonstration, can be by pressing
Key module realizes the operation such as playback, time-out, continuation that Chinese character is demonstrated.
By taking Chinese character " work " as an example, its complete display as shown in figure 3, in figure, the system upper right corner(Can also be other
Angle)For the origin of coordinates(0,0), the coordinate of each point is with a byte representation:High nibble is abscissa, low nibble to indulge seat
Mark(Also can be contrary).
So, according to the order write, it is possible to obtain the order of strokes observed in calligraphy dot matrix of Chinese character in Fig. 3 " work ":0xE2、0xD2、
0xC2、……、0x1D.It should be noted that the rightmost one of 16 × 16 Chinese character dot matrixs of standard arrange all be it is empty, this be in order to
There is " adhesion " in two words when avoiding showing or so.That is, defining according to the coordinate system in Fig. 3,0x00-0x0F this 16
Coordinate is no, can use it to the end mark as each Chinese-character order of strokes dot matrix.
The utility model is combined using existing ripe control technology and equipment, realizes completely drilling for Chinese-character order of strokes
Show, it not only contributes to improve the convenience and correctness of teaching, and the atmosphere for classroom increased interest.
Above-described embodiment is only one of preferred embodiment of the present utility model, be should not be taken to limit of the present utility model
Protection domain, it is all in body design thought of the present utility model and the change or polishing of having no essential meaning mentally made,
The technical problem that it is solved is still consistent with the utility model, should be included in protection domain of the present utility model it
It is interior.
