Doubt about Digital I/O lines

[SabariSaravanan.M]

Hello all,

          In my project am going to use 10,000 No's LED I/O's in single 100 No's I/O NI - card.

          Is it possible to use it?

That really depends on how the LEDs are being controlled.  Can you explain your project?

Hi crossrulz,

                     Ya sure I can explain about it. Here am using barcode scanner 10,000 I/O's which

                      means,100 rows * 100 columns = 10,000 I/O's (but hardware should be with

                     100 I/O channels).

                     For example If am scanning barcode for particular product but that product to be

                     located in (100 rows 100 columns) particular location. So that particular location

                     LED should be glow with GREEN color. After that I can choose it for verification.

                    Suppose if I choose/take wrong product from that 2D array instead of scanned

                    product that wrong location should be glow with RED color.
