Hi

is it possible to use a 4x20 LCD blue with backlit? I find one  to a very low price.

Just a little curiosity:  does lcd show only words in midibox sdi? or does it show any graphic?

No, it doesn't show any graphic, it's already (very) hard enough to bring all the code into the small flash ;-)

A 4x20 should work, it allows you to display up to 10 items at once, but you've possibly to do some modifications in the display layout (never tried this...)

Best Regards, Thorsten.

If I'm not mistaken, the 2 bottom lines are displayed as if it was a 40x2 display. At least that's what my test LCD did =) So, it should display 5 items in the top 2 lines and 5 in the lower 2 without any code changes.

Wow.  Is that true?  If so, I would love to do that and put buttons across the top and bottom, like this:

* * * * *

Can anyone confirm if that is how it works?  And..do you have any tips or reasons why my idea wouldn't work?

A 4x40 LCD has two independent data ports (or at least two independent enable lines), it behaves like two 2x40 LCDs

Hi Mikael,

you could - but when you are asking me, I would never replace two 2x40 by a single 4x40, the usage with two 2x40 is much better!!!

Best Regards, Thorsten.

Hi Mikael,

also the position of the LED wouldn't be correct.

Just the whole usage wouldn't be so perfect like with two 2x40 displays

Best Regards, Thorsten.
