Hello community
I'm new on the netuino world..
my problem is to find or to write a program for my netduino+ and the Devantech LCD03 with I2C Protocol
I searching on many Websites (Codeplex...) but i have never found a suitable program.
I only found this on the TinyCLR HP.
http://wiki.tinyclr....ch_LCD03_driver
there is the SOURCE Code and the LCD DRIVER but how can I implement this for the Netduino .NETF
The spec from the Display:

Try downloading the Micro Liquid Crystal Library and the Fusionware Spot Library from CodePlex. MLC handles the LCD, Fusionware.Spot handles the I2C. I am using a different 20x4 I2C LCD but this code works for mine.
You should probably use the overloaded MCP23008LcdTransferProvider method to pass in your address and shifter configuration in addition to the _bus.
The rest should be easy using:
LCD.Clear, LCD.Backlight, LCD.SetCursorPosition, LCD.Write.
Hope this helps.
using FusionWare.SPOT.Hardware; using MicroLiquidCrystal;
// Define the I2CBus private static I2CBus _bus; // Define the LCD Display private static Lcd LCD;
// Initialize I2C bus (only one instance is allowed) _bus = new I2CBus(); // Use I2C provider // Initialize provider (multiple devices can be attached to same bus) var lcdProvider = new MCP23008LcdTransferProvider(_bus); // Create the LCD interface LCD = new Lcd(lcdProvider); // Set up the LCD's number of columns and rows: LCD.Begin(20, 4);

Also... I looked at your code. I think it would work but you're missing your main subroutine.
Should look like this:
Should look like this:
namespace NetduinoPlusApplication1 { public class LCD03 { public static void Main() { LCD03 LCD = new LCD03(0xC6); // I²C protocol LCD.Cursor(LCD03CursorType.Hide); // Hides cursor LCD.BackLight(true); // Turn on backlight LCD.ClearScreen(); // Clears the screen LCD.Write(1, 1, "FEZ rocks"); // Displays some text } } }

@dvanderwekke
I have take a look to the 2 link's but it is too complicated for me to implement this links in my program
thank you although
I and my Project-Partner have written a new program and it works (our first sucess is that we can send anything to the Display, the next step is to implement a RTC (maxim DS1307) and a Keypad)
when we a ready with our Project (heating control system with a netduino+ and LCD) we release our Project for all.
for all user please post your suggestions / ideas or program

I was wondering of you have created any special characters for the LCD03?
If so how do you get them to be displayed on the display?
In particular the degrees symbol °.
