Hello,
I was wondering if it's possible to attach such a module.
And how should I wire it up to the Ez-B ? And what about scripting? Do you have any code samples?
Link to a LCD Module I'm gonna buy.

A serial LCD operates using a 1 wire connection. The EZ-B transmits "serial data" over a "baud rate" to the LCD by one of it's I/O pins. The baud rate is usually 9600, or higher.
How can I control the LCD connected to the Ez-b with Csharp?
Do you have any code samples?
Sorry for "too many questions" but this project is really interesting!
Thank you!

That being said, I'd start by downloading and modifying the following code to suit your needs:
Simple Scott Edwards Serial Backpack LCD Class and Example
I'm not sure how heavily the code will need to be modified (aside from adding the EZ-B connection) but the LCD you purchase should at least include documentation on the command structure to get you started...
I found what you need is just 8X2 character LCM ,for character LCM,only few people would like to choose serial ones .
But I can provide you some technical information .My email address : alinasales1988@gmail.com
I'll be more than happy to help you in anyway we can
Best Regards

I found an lcd screen in a computer to a friend (he gave it to me)
This one
It has an internal usb connector (4 pin) It's usual usb, so I guess its power, ground, and two signal cables?
But how to connect the cables to the Ez-B ? *confused*
Again, thank you!

Check this link for compatible LCD modules with the EZ-B: Clickity
Once you have the LCD module that is compatible with the EZ-B, check the TellyMate or Uart library for transmitting data to it. There are a few Tellymate examples in the EZ-SDK Package.
Optionally, if you are using the ARC software... You can easily write to serial by using the SendSerial() command...
Code:
(1) Download and install LCD Smartie to interface with your USB LCD.
(2) Create scripted events in ARC that fire off LCD Smartie commands to control the LCD ouput.
If this sounds like too much work or you absolutely need native control through the EZ-B you'll need to bite the bullet and purchase a serial or I2C LCD.
Hope this helps...
P.S. It takes some time to get your head around the EZ-B paradigm if you're used to a PC-centric computing model. My 2 cents...
DWIN 24-bit colored HMI kernel was put into production in August, 2010. It has won the market's affirmation because of its outstanding performance, functions and low cost. 24-bit colored HMI drove by H600 kernel is replacing the elder 16-bit colored HMI rapidly and become the better graphical interface of our customers' products.
DWIN 24-bit colored HMI based on H600 kernel now covers all the sizes from 5.0 inches with a resolution of 800x480 and 18.5 inches with a resolution of 1365x768, our product line covers the consuming class(C series) to automobile class(Q series) to meet the needs of different customers.
[u]Excellent performance on colors
Improve the display speed substantially
Any-angle rotation by software
Enhanced and optimized GUI decreases the effort and difficulty for further development.
Greatly raise the value for clients by systematic supply management [/u]
DWIN can supply low priced 24-bit color HMI with better quality than other European products. Even compared with the Industrial class Non-drivered LCD made in Japan, Korea and Taiwan, the advantages of DWIN's products are obvious.
With the information revolution and social progress, traditional LCD is too monotonous and inflexible to meet the demands from customers. DWIN is the best solution for making a better interface for your product you never seen before!

I usually buy 300 mm wires in bulks of 10 for $2-$3 with free shipping.

It has 16 pins in the "standard 1602A" configuration. I think I'm supposed to do the following:
1. Plug in a cable to one of the digital ports on the EZ-B
2. Solder the Ground to Pin 1
3. Solder the Positive to Pin 2
4. Solder the Signal to Pin 5
Optionally, I can plug in another cable to another digital port and solder the Positive and Ground to Pins 15 and 16, respectively to power the backlighting.
Do I just ignore the other pins? What about Pin 3? It's labeled "Contrast Adjust". How do I adjust the contrast if required?
Thanks!
the tutorial page on here specifies that it is best to use Serial Display. You can find the tutorial page by clicking Tutorials on the top menu. Or here is a shortcut for you: Serial LCD Displays
Did you ever get your i2C LCD?
