the display is 84x84 pixels, so each character needs to be defined by a bitmap telling which bits are on and off for a given character. Here is a little background if you are interested: http://www.instructa...g-a-custom-font

If you look at the first page of this thread, on the 7th post or so at the bottom it says:
"Notes: "NokiaCharacters.ASCII" is a public static class that contains the "public static byte[] ASCII = new byte[] {....};" thing. "

Basically take the byte array called ASCII from the 5th post on the first page and put it in its own class called NokiaCharacters.
Alternatively you could put the byte array right into your code.

Hope that helps,
Mike

Hello, I do not understand electronics and I’m starting with the development for netduino, I would like to know if you could tell me how to connect the LCD Nokia 5110 on the netduino with this breadboard.

I have exactly the same LCD, if you're patient, I shall try it later this week and post a breadboard-view on the wiki and PM you when it's done.

Hello Stefan, thanks again for the help, I'll wait then.

I'm going to make a wiki about it, but I used:
- NETMF Code (and help) from Omar
- Help from Steven (bitmap part on PC)

Posted Image

I can convert JPEG's, GIF's, etc. to a format that can be displayed on the display. Also, Omar's text-functions work superb.
When the wiki page is completed, I shall post again. (won't be today, needs some rest)

Hello Mario,

It is one of the most famous quotes by Blaise Pascal (Pensées book), I think in English would be something like
"The heart has reasons that reason cannot know."

O coração tem razões que a própria razão desconhece.

Stefan, I downloaded the project from the wiki page Nokia 3310 LCD

After trying to open the project it insinuated that I needed to upgrade to the 4.2 beta SDK and firmware, after upgrading I get the below output saying I need 4.1 again, I assume I can edit some files to fix? I am trying to find it now, not sure what I am doing, thanks for the help.

Hi

I just seen that the code for the LCD indeed has 4.2 as Target Framework Version. The version needs to be correct at 3 points:
- Visual Studio (can be changed, so you actually don't need to change firmware); go to the project's properties and modify the target framework.
- Software Development Kit (If you install the 4.2 SDK, it will also install the 4.1 SDK)
- Netduino Firmware (see http://wiki.netduino...ep-by-step.ashx for guidelines)

Updating the netduino to 4.2 doesn't need to be done. Which firmware do you currently have in your Netduino? You can find that out by starting MFDeploy.exe (at default installed at "C:\Program Files (x86)\Microsoft .NET Micro Framework\v4.1\Tools"), select USB->Netduino and click Target->Device Capabilities. This is an example of the firmware version:
SolutionReleaseInfo.solutionVendorInfo: Netduino (v4.2.0.0 b1) by Secret Labs LLC

Well, after setting the target framework in the .csproj to 4.1 and spending about three hours trying to revert my bricked Netduino+ firmware back to 4.1.1.0 after my botched attempt to upgrade it to 4.2, finally got it to work, thanks!

I love these little GLCD screens, will post if I make anything interesting.

Hi guys,

I've played a little with the code and found that we can't use text functions together with graphics - the text goes directly to the LCD than the graphic gets into the buffer first and than whole buffer transferred to display.
So I added functions DrawString and DrawChar that draw string into buffer first, so it can be combined with graphics and shown by calling Lcd.Refresh() function:

public void DrawString(int x, int line, string str, bool mode)
        {
            foreach (char c in str)
            {
                DrawCharacter(x, line, c,mode);

                x += 5; // 6 pixels wide

                if (x + 5 >= 84)
                {
                    x = 0;    // ran out of this line
                    line++;
                }

                if (line >= 48 / 8)
                {
                    return;        // ran out of space :(
                }
            }
        }

        protected void DrawCharacter(int x, int line, char c, bool mode)
        {
            for (int i = 0; i < 5; i++)
            {
                if (mode)
                    ByteMap[x + (line * 84)+ i] |= NokiaCharacters.ASCII[c - 0x20][i];
                else
                    ByteMap[x + (line * 84) + i] |=(byte) ~NokiaCharacters.ASCII[c - 0x20][i];
                //x++;
            }
        }

Regards,
Eugene
