Hey guys,

 

I'm a complete newbie at this.  

 

What I want to do:

A "Hello World" program to the lcd

 

What I've done:

I have a netduino plus 2 and I'm using VS Express for Desktop 11.0.  I'm coding in C#.  I have successfully run a few programs (blinky & pushing the onboard button).  I bought an lcd from sainsmart (lcd2004) that has an I2C interface.  I have wired it in to the 5v and ground and get power to the lcd.  I've also connected the SDA on the lcd to SD on the board, and SCL on the lcd to SC on the board.   

I've also searched all over and have not been able to find anything that will walk me through how to do this, step-by-step.  The closest I've found is http://bansky.net/bl...-port-extender/.  However, I am using the 4 pin connection.  I've spent hours watching videos and reading.  

 

Where I'm stuck:

Don't know what code is needed to "communicate" with the lcd.  Any help would be greatly appreciated.

 

Thanks!

Hi,

If your display uses HD44780 controller, you can try this library: http://microliquidcr...l.codeplex.com/ .

This link also helped me a lot in moving forward with writing my own programs in I2C for my internship. 

 

If your'e ever looking to develop your own library or driver, I couldn't find a better source to get started with.
