Hi everyone,
for an article I'd like to know the release dates of the Netduino boards, more specifically for the Netduino 2, the Netduino Plus 2 and the Netduino Go boards.
Thanks in advance,
yours
Robert

Thanks in advance, yours Robert Generating own NuGet packages04 September 2013 - 07:07 PM I have created a .NET MF class library and want to publish that on NuGet. Creating the NuGet seems to work fine, but when I integrate the NuGet package (it's called Enough.MF.Connectivity) I get the following errors in Visual Studio: Could not copy the file "[...]ProjectsLightOMatorpackagesEnough.MF.Connectivity.1.0.1libnetmfleLEEnough.MF.Connectivity.pe" because it was not found. Could not copy the file "[...]ProjectsLightOMatorpackagesEnough.MF.Connectivity.1.0.1libnetmfleLEEnough.MF.Connectivity.pdbx" because it was not found. Could not copy the file "[...]ProjectsLightOMatorpackagesEnough.MF.Connectivity.1.0.1libnetmfleBEEnough.MF.Connectivity.pe" because it was not found. Could not copy the file "[...]ProjectsLightOMatorpackagesEnough.MF.Connectivity.1.0.1libnetmfleBEEnough.MF.Connectivity.pdbx" because it was not found. I can fix that error by moving the files from packagesEnough.MF.Connectivity.1.0.1libnetmfle to packagesEnough.MF.Connectivity.1.0.1libnetmfleLE, etc. Comparing that to other Microframework NuGet packages (that work flawlessly out of the box) I can't really find any substantial difference other than those packages being tailored for specific .NET MF versions (with folders such as netmf42, etc). Something seems to point to the libnetmfle folder as the root, but I don't know what. I have attached the NuGet file, you can also download it under the ID Enough.MF.Connectivity. I create the NuGet package with following psake script: 1. building: Exec { msbuild "/t:Clean;Build" /p:Configuration=Release /p:OutDir=$tempBinariesDir /p:GenerateProjectSpecificOutputFolder=true /p:StyleCopTreatErrorsAsWarnings=false /m "$solution" } "Error building $solutionFile" 2. NuGet packaging: Exec { .$nuget pack $projectNugetFolder$projectNuspec -Output $nupkgDir } "Error packaging $name" When I unpackage the generated nupgk file, I get following folder structure: + _rels .rels + lib + netmf Enough.MF.Connectivity.dll Enough.MF.Connectivity.pdb SecretLabs.NETMF.Hardware.dll SecretLabs.NETMF.Hardware.Netduino.dll SecretLabs.NETMF.Hardware.Netduino.pdb SecretLabs.NETMF.Hardware.pdb + be Enough.MF.Connectivity.dll Enough.MF.Connectivity.pdb Enough.MF.Connectivity.pdbx Enough.MF.Connectivity.pe SecretLabs.NETMF.Hardware.dll SecretLabs.NETMF.Hardware.Netduino.dll SecretLabs.NETMF.Hardware.Netduino.pdb SecretLabs.NETMF.Hardware.pdb SecretLabs.NETMF.Hardware.pdbx SecretLabs.NETMF.Hardware.pe + le Enough.MF.Connectivity.dll Enough.MF.Connectivity.pdb Enough.MF.Connectivity.pdbx Enough.MF.Connectivity.pe SecretLabs.NETMF.Hardware.dll SecretLabs.NETMF.Hardware.Netduino.dll SecretLabs.NETMF.Hardware.Netduino.pdb SecretLabs.NETMF.Hardware.pdb SecretLabs.NETMF.Hardware.pdbx SecretLabs.NETMF.Hardware.pe + package + services + metadata + core-properties 407e9cf4968540ff98272fc0fb2a98a8.psmdcp [Content_Types].xml Enough.MF.Connectivity.nuspec
Thanks in advance for any pointers, Robert SerialPort / Itead Studio Bluetooth Shield V2.222 June 2013 - 09:37 AM Hi everyone,
My problem: I cannot receive data using the Itead Studio BT V2.2 on my Netduino Plus 2.
My analysis (note that I'm total noob when it comes to electronics):
The shield itself seems to be working, I can connect to it using my Windows Phone app, the blinking LED on the shield then switches to the 'connected' blinking mode as expected. I send data to the StreamSocket on my Windows Phone and flush the stream without problems. However, on Netduino I am unable to receive data on the SerialDataReceivedEventHandler.
The shield has a UART Multiplexer, the description from the product shield confuses me a bit (attached).
Here's a crude ASCII art of the multiplexer:
[font="'courier new', courier, monospace;"] 0 14567[/font] [font="'courier new', courier, monospace;"]____________[/font] [font="'courier new', courier, monospace;"]| [] OOOOO | TX[/font] [font="'courier new', courier, monospace;"]| [] OOOOO | D0 | D1 D4 D5 D6 D7[/font] [font="'courier new', courier, monospace;"]| [] OOOOO | RX[/font] [font="'courier new', courier, monospace;"]------------[/font]
I figured that the TXD side defines the transferring digital port and RX the receiving one.
Now typically I would expect to be able to use D0 and D1 (aka "COM1") for the serial communication. This leads me to believe that I need to set the jumpers like this on the multiplexer (one green, one red):
C1: [font="'courier new', courier, monospace;"]____________[/font] [font="'courier new', courier, monospace;"]| [color=rgb(0,255,0);][][/color] OOOOO | TX[/font] [font="'courier new', courier, monospace;"]| [color=rgb(0,255,0);][][/color] [color=rgb(255,0,0);]O[/color]OOOO | D0 | D1 D4 D5 D6 D7[/font] [font="'courier new', courier, monospace;"]| [] [color=rgb(255,0,0);]O[/color]OOOO | RX[/font] [font="'courier new', courier, monospace;"]------------[/font]
or like this:
C2: [font="'courier new', courier, monospace;"]____________[/font] [font="'courier new', courier, monospace;"]| [] [color=rgb(255,0,0);]O[/color]OOOO | TX[/font] [font="'courier new', courier, monospace;"]| [color=rgb(0,255,0);][][/color] [color=rgb(255,0,0);]O[/color]OOOO | D0 | D1 D4 D5 D6 D7[/font] [font="'courier new', courier, monospace;"]| [color=rgb(0,255,0);][][/color] OOOOO | RX[/font] [font="'courier new', courier, monospace;"]------------[/font]
For the configuration C1 above the description says:
You can use the jumper to connect the TXD and RXD pins of HC-05 to D0, D1, D4~D7 pin of Arduino.
For the configuration C2 above the description says: When using the connection as Figure C2, the HC-05 connects with the FT232RL chip, and the FT232RL connect to PC by USB. Whit this configuration you can use the serial software on PC to control or configure the HC-05 module.
For other jumper configuration the description says: Except the 2 configurations above, you can connect the TXD and RXD to any other pins from D4-D7, and using the software-serial library to control the HC-05 module.
So it seems to me that I cannot use neither C1 nor C2 but instead need to place the jumpers to other configurations. However, I did not figure out a working configuration.
When using COM1 I never receive data. When using COM2 I always receive various length of byte arrays, that's interesting but as the multiplexer does not server D2/D3 at all, I guess that is something completely different going on there (told you I'm a noob). From this post: http://forums.netdui...opic/4999-com3/ I think that COM3 uses D7/D8 which is a bit of shame, as I only have D4 - D7 available above.
So, am I doomed? Can anyone recommend a stackable shield that works fine with my Netduino Plus2?
Thanks in advance, Robert

Now I wonder how to start my actual idea: I want to control lights according to the time of the day (e.g. having more blue light in the morning, but more red light in the evening),
Wifi is discussed in several threads here, so I guess that can be solved. About the light I am not so sure - I am thinking about RGB LED arrays such as the
