Re: 2lcds to one pic

Hi,

Don't see why not, used as is, it will display the same message on both screens.

If you modified the code, so each lcds E line had its own dedicated pic pin you could then output different messges to each screen.

So long as R/W is held low so that you are only writing to the display and not reading, it should not be a problem, you could have several displays depending on the drive capability of your source. As wp100 says controlling each Enable with a separate pin, would mean that you could decide which or all would display.

Re: 2lcds to one pic

Thank you all

I finished everything

it worked well

:)

Added after 8 minutes:

possible.vishnu,

I do not know which compiler you are using

i suggest you download mickro basic or c compilers

there are good examples in the " help section"

for a 16x2 lcd , all u have to do is to get to know
how to set pins to digital ( refer to your datasheet if you have no idea how)

anyway the examples will help you
with ease

cheers

If you are thinking of using CCS compiler, check out their forum and search for flex_lcd, there are a few for different types of display. Even if you are using a different compiler, they should be fairly easy to modify.
