PV750 screen shield unlock with password

Post by twang » Wed Nov 02, 2011 3:46 am

Hello,

I got an application from customer side who used our PV750 as the display communicated with other controller.
When controller sent a data then the whole screen will be shield(overlay) by a 800*480 size pictures . Under this occasion , they customer want to use the following action to unlock the screen:

Go back to menu -> Screen manager ( can be added unde rUtilities Menu)-> key pressed enter into Screen manager and generated a Dynamic Password (six numbers between 0~9)...

The problem is I don't know how to generate this password....

Your quick respond will be appreciated..

Terry

Hello Terry

Six variables can be used to hold the six numbers.

You can use an algorithm to generate numbers for the six variables. I do not believe Angel Script has a random number generator.

Let us know if you have any more questions. Thank you!
