Hi folks, Been a good while since I last used my Netduino, but got it out last night to mess around with the eithernet shield I have. Last time I used it there didn't seem to be a way to use the SD card, I'm just wondering if that has changed with new firmware etc? Any help would be great. Cheers Raymond

Hi, Wondering if anyone can help me. I'm currently using an Ethernet shield and my netduino but am having a bit of bother sending data from a specific port using a UDP socket. I can set up my socket fine and send data TO the correct port, however I am always sending FROM a random port, where I would like to be sending from the same port every time. The sending part of my code looks like: IPAddress thisIP = IPAddress.Parse(netInterface.IPAddress); IPEndPoint thisEnd = new IPEndPoint(thisIP, 68); udp.Bind(thisEnd); IPEndPoint broadcast = new IPEndPoint(IPAddress.Parse("255.255.255.255"), 67); udp.SendTo(data, broadcast); I was under the impression the bind would cause the socket to send from the specified port and not a random one like it does when it's unbound, however I can't get this to work. Any help would be appreciated. Thanks

Hi folks,

This is the first project I've posted up here and my first that has been anything more than a test.

Basically I have a BlinkM (RGB LED) which I communicate with over I2C. On a push of the onboard switch the BlinkM is told to start playing a script which cycles through the basic colours (R->G->B->W). While the script is playing the netduino asks the BlinkM for its RGB values every 200 milliseconds.

The netduino then puts these values in a formatted string and writes the string to the LCD screen.

There’s not a huge amount going on in all honesty, but it’s a good example of what these components can do and hopefully will be good reference for anyone else that wants to start using them.

I’ve also tried to write my classes for the components so they will be easily extendable as I intend to use them in any other projects that require the LCD screen or BlinkM, so feel free to take them and make them your own if you like.

Finally I’d like to thank Pete Brown for his very helpful blog post about using a HD44780-controlled LCD Display with the netduinoo and also Szymon Kobalczyk for the awesome μLiquidCrystal library which I use in this project.

For a video overview please see this youtube vid.

I have also attached my project files for reference if anyone would like them.

Hi folks, This is my first post on the forums so hi After getting my Netduino a few weeks ago I've worked up from blinking LEDs to using a BlinkM and a LCD screen but to be honest I'm still very new to all this. I want to put what I've done with the individual components together with an Arduino Ethernet Shield and SD card that I got for my main project. I've searched the fourm and seem to have found conflicting information on using this shield. First off is is possible to even use the SD card slot with the firmware that comes as standard on the netduino, or do I need to upgrade to a newer one? Is this also the case for the Ethernet part of the shield? Finally if anyone has seen a blog post etc by anyone who has used this shield with the netduino before or has any advice please point me in the right direction. Thanks Raymond
