For ease of understanding, the embodiment described by Fig. 2, is described a kind of combination startup LOGO display in the embodiment of the present invention with a practical application scene below:
Fig. 3 is the cascade structure schematic diagram of combination, altogether M*N screen, then the address of each screen is 1,2 ... M*N.
1) each combination screen need distribute the storage space (we are assumed to space A) of one piece of rewritable herein, and this space can be used for storing LOGO pictorial information;
2) control end (this control end can be computer) reads the LOGO pictorial information that will change;
3) the LOGO pictorial information read sends to all screens to receive by digital serial port by control end;
4) data layout that the LOGO pictorial information received is converted to screen itself by these screens is stored in specific storage space A, completes the renewal of LOGO data;
Be more than the operation steps of every block screen update LOGO picture in combination, here is the steps flow chart of screen display LOGO picture:
5) read LOGO pictorial information, obtain the display information LOGO_width (LOGO picture wide) of LOGO picture, LOGO_high (height of LOGO picture);
6) after M*N splicing segmentation, the LOGO that actual each screen need show is wide is then width=LOGO_width/N, high=LOGO_high/M with height;
7) calculate X and the Y position of screen in splicing system according to the address ID of screen, have:
Y=[(ID-1)/N], divided by the integral part of columns N after namely getting ID address decrement
X=(ID-1) %N, the remainder of trying to achieve with columns N after namely getting ID address decrement
Note: the implication of ID-1 is because address is from 1 herein ... M*N, and the calculation from 0 of the actual address of mathematical computations is 0 ... M*N-1.
8) according to 6) and 7) obtain each screen partition display LOGO region:
X_Start＝X*width
X_End＝X*width+width＝(X+1)*width
Y_Start＝Y*high
Y_End＝Y*high+high＝(Y+1)*high
9) cut zone (X_Start will calculated, Y_Start, X_End, Y_End) intercept out from original LOGO and be shown on each screen, each screen all shows different regions, and all M*N screen is the display of whole screen splicing LOGO altogether.
Be more than that in this practical scene, LOGO picture is changed and the flow process of display, wherein, from step 1) to 4), the control end of whole splicing system and every block screen of combination divide other operation can be as follows:
One, control end:
A) after LOGO image data reads, send and start to receive the instruction of LOGO image data to every block screen of combination, screen is entered and receives LOGO data mode;
B) the LOGO image data that reads is sent to screen, until all LOGO image datas are sent completely;
C) send end and receive LOGO data command to screen, make screen exit reception data mode, carry out data processing.
D) control end software process is completed.
Two, every block screen of combination:
A) receive and start to receive the instruction of LOGO image data, display end enters and receives LOGO image data state;
B) start to receive the LOGO image data that control end sends over, terminate to receive instruction until receive;
C) receive end and receive the instruction of LOGO image data, exit and receive LOGO image data state;
D) process the LOGO image data received, result is stored in LOGO storage space A;
E) replacing of screen LOGO picture is completed.
