sirs.,.,i need help in getting data from LCD display...
i want to read the data from LCD(a) and display it to LCD(b)...

LCD(b) is connected to my arduino as my main device.


if you could spare me sample codes, that would be a great! thanks in advance.

Can't you just connect the lines from LCD(a) to LCD(b) so that the two LCDs are driven at the same time? In this way you won't need to read anything, just put a second LCD in parallel with the first, you won't even need to write code for it.

Also a similar thread on this:

Hope this helps.

why you want to display the same data on both LCDs???

LCD is a device that can only accept the data and commands. it can not send. so if you want the data of 1 LCD to be displayed on the other LCD. you should connect the data lines of 1 LCD to the other. means you should connect both lcds in parallel as said by alexxx.
