Hi all! I used to be AVR developer, an I need some thing I used to use. What I want to do is, obtaining a binary file from my code, and be able to write it in Netduino without need to rebuild my code. Do you know any way to do this?

There is another way, but neither works in Micro Framework:
3)

using System.Diagnostics;
// get call stack
StackTrace stackTrace = new StackTrace();
// get calling method name
Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name);

Do you know any way to see current method name?

I know this two options, but they are for Framework:

1)

MethodBase method = (new StackTrace(true)).GetFrame(0).GetMethod();
string methodname = method.DeclaringType.FullName + "." + method.Name;

2)

MethodBase method = MethodInfo.GetCurrentMethod();
string methodname = method.DeclaringType.FullName + "." + method.Name;

Any idea about how to do it in Micro Framework?

I'm building an app, that uses serial port. Are there any way to get access to serial ports using the emulator? What I want to do is read from a serial port using the emulator. I've tested this in Netduino+ and it works ok, but I also want to test in emulator. Thanks!!

I've been developing with Atmel uC for some years, and I had never found this problem. I can tell you that I've developed some big projects, but always using C. My favourite micro use to be AtMega32.

I'm having some space issues so I want to try this. Could be possible load some of my assemblies dynamically in order to leave some ROM free??

I'm working over this code:

using System;
using System.IO;
using System.Reflection;
using System.Threading;
using Microsoft.SPOT;
//using SecretLabs.NETMF.IO;

namespace MonoNetduinoBootloader
{
    public class Program
    {
        public static void Main()
        {
            FileStream assemblyStream;
            Assembly assembly;
            object netduinoAppClassInstance;
            MethodInfo startupMethod;

            // for Netduino and Netduino Mini: mount the SD card
            try
            {
                // uncomment for netduino
                //StorageDevice.MountSD("SD", Microsoft.SPOT.Hardware.SPI.SPI_module.SPI1, (Microsoft.SPOT.Hardware.Cpu.Pin)54);

                // uncomment for netduino mini
                //StorageDevice.MountSD("SD", Microsoft.SPOT.Hardware.SPI.SPI_module.SPI1, (Microsoft.SPOT.Hardware.Cpu.Pin)12);

                // netduino plus will auto-mount SD card
            }
            catch
            {
                Debug.Print("SD card could not be mounted.  Please verify that SD card is inserted.");
                return;
            }

            // make sure the assembly exists
            try
            {
                // open the netduino app assembly, built using Mono.
                assemblyStream = new FileStream(@"\SD\MonoNetduinoApp.pe", FileMode.Open, FileAccess.Read, FileShare.None);
            }
            catch
            {
                Debug.Print("Netduino app not found.  Please copy MonoNetduinoApp.pe to root folder of SD card.");
                return;
            }

            // attempt to load the assembly into RAM
            try
            {
                // read the assembly into RAM
                byte[] assemblyData = new byte[assemblyStream.Length];
                assemblyStream.Read(assemblyData, 0, assemblyData.Length);

                // load the assembly
                assembly = Assembly.Load(assemblyData);
            }
            catch
            {
                Debug.Print("Netduino app corrupted.  Please check MetaDataProcessor settings.");
                return;
            }
            finally
            {
                assemblyStream.Dispose();
            }


            // using reflection: get the type of the MonoNetduinoApp's startup class; get the statup class's type; using the startup class's, get a reference to the type's Main method.
            try
            {
                netduinoAppClassInstance = AppDomain.CurrentDomain.CreateInstanceAndUnwrap("MonoNetduinoApp, Version=1.0.0.0", "MonoNetduinoApp.Program");
                Type netduinoAppClassType = assembly.GetType("MonoNetduinoApp.Program");
                startupMethod = netduinoAppClassType.GetMethod("Main");
            }
            catch
            {
                Debug.Print("Netduino app invalid.  Please verify that class name is MonoNetduinoApp and startup method is Main.");
                return;
            }

            // run the MonoNetduinoApp's startup routine (MonoNetduinoApp.Program's Main method)...starting our app.
            startupMethod.Invoke(netduinoAppClassInstance, new string[] { });
        }
    }
}

As you can see, this is the code of Mono Bootloader. My idea is load some assemblies like:

• using Microsoft.SPOT.Native
• using Microsoft.SPOT.Hardware
• System.IO

And some others...

The problem comes with this:

netduinoAppClassInstance = AppDomain.CurrentDomain.CreateInstanceAndUnwrap("MonoNetduinoApp, Version=1.0.0.0", "MonoNetduinoApp.Program");
Type netduinoAppClassType = assembly.GetType("MonoNetduinoApp.Program");
startupMethod = netduinoAppClassType.GetMethod("Main");

Can I add more than one assembly?? If I want to load an entire class, what have I to write in netduinoAppClassType.GetMethod??

Thanks!!!

Not much, I actually ended up taking regex out because the referenced assemblies were 30k just but themselves

I think this is the big problem with Netduino. If you test the sample codes, for example all code in Getting Started with the Internet of Things, but when you begin making some bigger you will realise that you can't flash your firmware because it is bigger than the amount flash available.

How many free ROM is this firmware going to leave for us??? Actually we only have 64KB.

I tried with 3 different libraries and no one is working for me:

jae@newton:~/Desktop/netmfbins$ wine MetaDataProcessor.exe -loadHints mscorlib mscorlib.dll -parse MicroHTTP.dll -minimize -endian le -compile cosa.pe

fixme:heap:HeapSetInformation (nil) 1 (nil) 0
Cannot open 'MicroXBee.dll'!
MMP: error MMP0000: 0x80070002

I think I've installed everything properly.

Error   1       An error has occurred.  Please check your hardware

I've read that this error is showed when you try to write a bigger assembly than allowed...

It's about 117KB when maximum allowed is 64KB.

The debugging target runtime is loading the application assemblies and starting execution.

I'm working with Micro Framework 4.1 (computer and netduino+'s firmware).

After adding (again) the references, and build the solution...

Deploying assemblies for a total size of 120600 bytes

Error	1	An error has occurred.  Please check your hardware

Any other idea???

What are the errors?

Most of them are "namespace doesn't exist or can't be found..." (this doesn't happen if I select Debug).

Well, almost - you'd need to change the active configuration in the combobox in the toolbar from "Debug" to "Release".

The project settings tab you've shown allows you to specify various configuration options, independent of what is selected as active (in the combobox). After you select "Release" in the combobox, you will be actually building it, and you will have "Configuracion: Active (Release)" in the tab (now you have "Active (Debug)").

Edit: Attached picture.

I think this is almost configured, but now I'm having some troubles:


Do you know why is this happening???

You are talking about this, doesn't it?


I've tried with Release, Debug and Debug (Active) and I'm always having the same problem. I've also chosen "Optimize code" inside "Generate".

Are you using a debug build or a release build?

I don´t really know. How can I see this??

Are there any firmware that gives developer higher RAM amount?? I need networking, but after shrink my code it still is too big. Any idea??

In addition to what CW2 said, you can try the firmware in http://forums.netdui...te-50-more-ram/ to see if that suffices for you.

May main problem is the free ROM space. Having more RAM only be useful if I load assemblies dynamically from an SD card...

Is this going to be available in 4.2 final?

Checked. My program is around 96KB, but if it is bigger than 64KB compiler gives an error.

What exactly means this???

● Code Storage: 64 KB
without networking: 128 KB

Are there any way to prevent using network and having all 128KB for my program???

Thanks!!!

Hi! I'm having some issues and I think they are related with deployment size. How can I see how big is my program and who is using my free bytes?

I'm using lots of references, are there any way to see how big is each one??

After compiling I can see something like this:

What does RAM and METADATA mean?? What is the ROM amount available in my Netduino Plus?? I seen in specifications it is 64 KB and 128KB without networking. What does it mean?

Thanks!!!

Any updates?? We can't wait for it

Hi! I'm porting some code from .NET to Micro Framework.
One of the instructions I've is this:

_devic = Convert.ToByte(ByteUtil.GetString(aux), 16);

What I need to do is convert an string that is in base 16 to a number. Then convert it into a byte.

The main problem is that I can't convert from base 10 to base 16...

After looking some info, I've seen that MicroFramework Convert.ToByte method has only one argument so I can't choose what the base is needed. Do you have any idea about how to solve this???

I've the same problem using Convert.ToUInt64, Convert.ToSByte...

Thanks!!!

Doesn't look very plus to me

Today, neither to me

Thank you for te information!

Yeah I want the PLUS model so Bricogeek option is not possible but I've contacted with them and they hope to have the Netduino Plus in 2010 October. I'm waiting for seeing final price and if it's affordable I'll get it there

I supose I'll be back soon!

In 2010?
