4 display controllati tramite labview

Salve a tutti, ho un problema da risolvere. Ho 4 display da 320 colonne per 240 righe e tutti e 4 i display servono a formarne uno più grande. Ogni display è controllato da un driver che tramite interfaccia USB ottiene le immagini da visulaizzare tramite software di appartenenza. Supponiamo ora di voler visualizzare una foto, immagine di 640x480; significa che l'immagine dovrebbe essere divisa i 4 parti ognuna delle quali deve poi essere inviata a uno dei 4 display tale da visualizzarla completamente. é possibile realizzare tramite labview un programma che mi splitti in 4 l'immagine originale e che riconosca in automatico il display a cui ognuna di queste sotto-immagini debba essere inviata? Naturalmente le 4 sotto immagini devono arrivare sui 4 display contemporaneamente.

 

Ringrazio in anticipo chi mi risponderà

saluti

Hi, I have a problem. I have 4 display of 320 columns by 240 rows used to form a larger one. Each display is controlled by the driver via a USB interface to display the images obtained by software belonging. Now suppose you want to view an image of 640x480, it means that the image should be divided into the 4 parts, each of which must then be sent to one of the 4 display that view completely. Is possible via a labview program that I split it in 4 the original image and that the program automatically recognizes the display to which each of these sub-images to be sent? Of course the 4 parts of the total should reach about 4 displays at once.

 

thanks

I guess It is possible. You need to write code to split  image data into 4.You can always define which part to be sent to which display.

like Subset 1= display 1...like that.

infatti! ma è già presente nel forum un codice simile? Inoltre il software come potrebbe capire a quale porta usb indirizzare le varie parti dell'immagine?

Indeed! but it is already present in the forum a similar code? Moreover, the software could understand as to which port usb address the various parts of the image?

I don't know about example...Also software can not decide on its own. You need to code as to assign one port to one display.

Can you show us your attempt so far?

I have not made any attempt, because I do not have clear ideas. I would at least know if you can simultaneously send the 4 parts of a 4-port usb. while I believe that the division of the image into 4 parts can be achieved by identifying the coordinates of pixels. true?
