I've written a code using your library, but it is not working. can anyone take a look?

using System;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.Threading;
using Microsoft.SPOT;
using System.IO.Ports;

namespace SerialPortLearn
{
    public class Program
    {
        static OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
        
        static SerialPortHelper serialPortHelper1 = new SerialPortHelper();
        static SerialPortHelper serialPortHelper2 = new SerialPortHelper(SerialPorts.COM2, 9600, Parity.None, 8, StopBits.One);

        public static void Main()
        {
            while (true)
            {
                string line = serialPortHelper2.ReadLine();
                if (line.Length > 0)
                {
                    led.Write(true);
                    serialPortHelper1.PrintLine("Leido: " + line);
                    Debug.Print("Leido: " + line);
                }
            }
        }
    }
}

I'm able to write in UART, but reading method is not working.
Any idea? 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.

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.

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

I'm receiving via UART some data that are saved into a byte array, the problem is that I want to print this data using Debug.Print one of the ways I've thought is converting this to an Hexadecimal string, but Micro Framework does not support BitConverter.ToString.

Any idea? Thanks!!

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

I think I've installed everything properly.

Is this going to be available in 4.2 final?

I've a problem working with UART. I'm using SerialPortHelper library. But I can only write, not to write anything.

WTF! This happens when you have not asleep enough, sorry. I want to mean, that I'm able to write in UART (this part of code is working well), but I can't read from there.
I've neither written well the code. This is the real code I'm using:

using System;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.Threading;
using Microsoft.SPOT;

namespace SerialPortLearn
{
    public class Program
    {
        static SerialPortHelper serialPortHelper1 = new SerialPortHelper();

        public static void Main()
        {
            serialPortHelper1.PrintLine("Initializing...");
            while (true)
            {
                string line = serialPortHelper1.ReadLine();
                if (line.Length > 0)
                    serialPortHelper1.PrintLine("Readed: " + line);
            }
        }
    }
}

Thanks!!

Finally I've modified ReadLine() method and now it's working, but I'm still having a problem. I've defined two different objects (one for each port) but there is something that is not working.

using System;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.Threading;
using Microsoft.SPOT;
using System.IO.Ports;

namespace SerialPortLearn
{
    public class Program
    {
        static OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
        
        /*Defaults to: SerialPorts.COM1 (uses D0 and D1), 9600, Parity.None, 8, StopBits.One*/
        static SerialPortHelper serialPortHelper1 = new SerialPortHelper(SerialPorts.COM1, 9600, Parity.None, 8,StopBits.One);
        static SerialPortHelper serialPortHelper2 = new SerialPortHelper(SerialPorts.COM2, 9600, Parity.None, 8, StopBits.One);

        public static void Main()
        {
            serialPortHelper1.PrintLine("Starting!");
            while (true)
            {
                string line = serialPortHelper2.ReadLine();
                if (line.Length > 0)
                {
                    led.Write(true);
                    Thread.Sleep(500);
                    serialPortHelper1.PrintLine("Read: " + line);
                    led.Write(false);
                }
            }
        }
    }
}

The problem is that response, serialPortHelper1.PrintLine("Read: " + line);, is sent to port 2 instead of port 1. I think, maybe it's needed to modify constructor in order to work with both ports at simultaneously.

I've a problem working with UART. I'm using SerialPortHelper library. But I can only write, not to write anything.

Here is my code:

using System;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.Threading;
using Microsoft.SPOT;

namespace SerialPortLearn
{
    public class Program
    {
        static SerialPortHelper serialPortHelper1 = new SerialPortHelper();

        public static void Main()
        {
            serialPortHelper1.PrintLine("Initializing...");
            while (true)
            {
                if (line.Length > 0)
                    serialPortHelper1.PrintLine("Readed: " + line);
            }
        }
    }
}

Can anyone help me?? Thanks!!!

            Thread.Sleep(500); // LCD is slow, pause for 500ms before sending more chars
        }
    }
}

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).

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???

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.

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???

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

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

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...

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".

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!!!

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??

Are you using a debug build or a release build?

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

Has new firmware finally released??

Hi magarcan,

We're waiting for the final .NET MF 4.2 release. It's supposed to be two weeks behind the RC2 release...will probably be out within a week or so. Then we'll build a series of new firmware releases based on "gold" code.

Chris

Ok, so we will be waiting for this. But... what have we to do in order to update firmware?

Any updates?? We can't wait for it

When it's done and all downloads are provided:

- Re-install both SDK's (Microsoft's and Netduino's)
- Flash your tinybootloader (http://wiki.netduino...ep-by-step.ashx)
- Install new firmware (http://wiki.netduino...ep-by-step.ashx)

Thanks!! Now, we only have to wait firmware and new NETMF to be released.
