#46887 Netduino 2 Mini planned?

Posted by awaiK on 08 March 2013 - 01:47 PM in Netduino Mini

[...] The current version should be proudly posted on the hardware page [...]

Definitely!

#44515 Netduino 2 Mini planned?

Posted by awaiK on 29 January 2013 - 07:01 PM in Netduino Mini

I would love to see a netduino mini successor =)

#38710 Introducing Netduino Plus 2

Posted by awaiK on 08 November 2012 - 06:21 AM in Netduino Plus 2 (and Netduino Plus 1)

Awesome Chris! Can't wait to see it on european distributors (Amazon US doesn't ship to europe). Is the a limited edition or a regular new family member?

#38024 Documentation

Posted by awaiK on 27 October 2012 - 06:28 PM in Project Showcase

Hi Chris,

I was wrong. I should express myself more precisely.

What I'm missing are XML documentation comments (XML Documentation Comments) for NETMF classes.

Moreover: Sometimes I whish I had more information about PWM on netduino like the range of frequency, duty cycle, etc. which is possible on netduino hardware. I'm not that familiar with PWM, maybe this information is availabe but I'm not able to interpret it.

#37997 Documentation

Posted by awaiK on 27 October 2012 - 10:32 AM in Project Showcase

The netduino SDK definitely lacks documentation.

#37831 NetDuino/xbee code

Posted by awaiK on 23 October 2012 - 08:24 AM in Netduino Mini

Hm, the PC-side code and the netduino code should be smiliar.

You need to connect the XBee to netduino's TTL-level serial port.
Open the serial port and listen to the proper bytes on which you want to switch the LED.

private static SerialPort serialPort;
private OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);

public static void Main()
{
	serialPort = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);
	serialPort.Open();
	serialPort.DataReceived += new SerialDataReceivedEventHandler(serialPort_DataReceived);
	
	Thread.Sleep(Timeout.Infinite);
}

private static void serialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)  {
	// Read the bytes and switch LED
        led.Write(true);
}

#36587 Compiling and deploying a release code

Posted by awaiK on 05 October 2012 - 05:03 PM in Netduino Plus 2 (and Netduino Plus 1)

Yes, this should work. But step 1 and step 2 are unnecessary. On tab "Debug", "Build", ".NET Micro Framework", etc. you can specify the setting which are used during a build. A shorter way for step 3 is to use the drop-down control right next to the Start Debug button in the toolbar. Note: "Debug" and "Release" are just names for the building template. You can create your own templates to specify your own settings during a build.

#36512 Powering from 5V power supply

Posted by awaiK on 04 October 2012 - 08:12 AM in Netduino Mini

Thanks Nevyn, now it's 100% clear.

#36500 Powering from 5V power supply

Posted by awaiK on 03 October 2012 - 08:45 PM in Netduino Mini

Thanks for the info. The tech specs page says 7.5 - 12.0 VDC, so I thought 5V isn't possible.

#36495 Powering from 5V power supply

Posted by awaiK on 03 October 2012 - 07:24 PM in Netduino Mini

Hi, I'm affraid it is not possible, but...: Can I power a netduino mini from a 5V power supply, directly? (Without using additional components like a DC-DC converter)

#36356 Shared COM1 Issues

Posted by awaiK on 01 October 2012 - 10:48 AM in Netduino Mini

Thats a great info! Thanks Chris

#36199 Shared COM1 Issues

Posted by awaiK on 28 September 2012 - 07:28 PM in Netduino Mini

Hi, yes, thats a problem. You have to reserve one COM port for debug and deployment. Maybe you can try the following: Define an interupt which dispose at least one of your COM ports to enable debug and deployment. The interupt can be trigged by an external switch.

#35866 COM1 voltage level

Posted by awaiK on 23 September 2012 - 08:31 PM in Netduino Mini

Ah okay! Thanks for the clarification. I missed Chris's answer first.

#35864 COM1 voltage level

Posted by awaiK on 23 September 2012 - 07:12 PM in Netduino Mini

Hi awaiK,

Since pin 12 is the UART_RX pin, the FTDI USB-TTL converter chip on that board is most likely putting a 5V signal to pin 12.

Also...to turn on/off pins, use the Pins.GPIO_##### enumeration, not Cpu.Pin.GPIO_Pin5. They look similar, but Cpu.Pin refers to the pins on the microcontroller itself (rather than the pin #s on the Netduino Mini).

Chris

Hi,

using the right enum I can toggle the pins on/off... <_<

Turning pin 12 off and on via OutputPort, the pin is at 3.3V.
Disposing the OutputPort it switchs back to 5V.

So...it is broken and I need to buy some new ones?

#35851 COM1 voltage level

Posted by awaiK on 23 September 2012 - 08:12 AM in Netduino Mini

[...] Can you take a photo of your Mini attached to the multimeter/oscilloscope?

I took a photo using a multimeter

Also just to confirm--you can turn pin 12 on and off via OutputPort, correct?

I realized I can't switch any GPIO on nor off.

The following code should turn pin 5 definitely off:

public static void Main()
    {
        OutputPort pin5 = new OutputPort(Cpu.Pin.GPIO_Pin5, false);
        pin5.Write(false);
        Thread.Sleep(Timeout.Infinite);
    }

#35839 COM1 voltage level

Posted by awaiK on 22 September 2012 - 09:16 PM in Netduino Mini

pins 11 and 12 on my mini both output 3.3V

Thanks for checking.

Really strange: I have two netduino minis, both have 5V on pin 12.

#35825 COM1 voltage level

Posted by awaiK on 22 September 2012 - 04:22 PM in Netduino Mini

No other module is connected to the netduino.

The deployed program is:

public static void Main()
{
    Thread.Sleep(Timeout.Infinite);
}

Voltage samples:

Pin 1: -6V
Pin 2: -6V
Pin 3: -6V
Pin 5: 3.3V
Pin 6: 3.3V
Pin 7: 3.3V
Pin 8: 3.3V
Pin 9: 1.7V
Pin 10: 1.7V
Pin 11: 3.3V
Pin 12: 5V

Pin 12: 3.3V
Pin 13: 3.3V
Pin 14: 3.3V
Pin 15: 3.3V
Pin 16: 3.3V
Pin 17: 3.3V
Pin 18: 3.3V
Pin 19: 3.3V
Pin 20: 3.3V
Pin 21: 5V
Pin 22: 3.3V
Pin 24: 4.5V

#35822 UART data flow control on netduino Mini

Posted by awaiK on 22 September 2012 - 03:18 PM in Netduino Mini

Thanks for the explanation. For now I connect the target device's CTS and RTS pins together to bypass the hardware handshake.

#35821 COM1 voltage level

Posted by awaiK on 22 September 2012 - 03:14 PM in Netduino Mini

I'm looking with an oscilloscope on pin 12 and it's at 5V. Is there a pull-up resitor or something like that? A device which I want to connect to COM1 has problems with this 5V. The connected device is powered up by netduinos pin 12, even if I turned the device's on/off switch to off.

#35819 COM1 voltage level

Posted by awaiK on 22 September 2012 - 03:05 PM in Netduino Mini

Hi, it seems to me the netduino mini COM1 port (pin 11-12) use 5V for TTL signals. But it should use 3.3V, right? Since I'm not that hardware-expert, would be really nice if somebody can check his netduino mini COM1 port, which voltage level is used.

#35711 Can't Deploy Application from VS 2010

Posted by awaiK on 21 September 2012 - 04:02 PM in Visual Studio

Similar behaviour with my netduino (mini).
After a while, trying to deploy a second (or third) time, Visual Studio says

Unable to communicate with device - Serial:COM10

Edit: False alert. It's a different situation.
I changed my program from COM1 to COM2. But I use COM2 to deploy the application.
I guess because my program use COM2 now, Visual Studio can't deploy a new application.

#35591 UART data flow control on netduino Mini

Posted by awaiK on 20 September 2012 - 01:16 PM in Netduino Mini

Hi, am I correct that, there are no dedicated CTS/RTS pins to enable hardware-based data flow control? So, I have to implement data flow control by myself using two GPIOs?

#35008 New "Hardware" webpage

Posted by awaiK on 11 September 2012 - 07:03 PM in General Discussion

Great! Thanks. But...one family member is missing.

#34827 visual Studio 2012 and netduino plus

Posted by awaiK on 07 September 2012 - 04:44 PM in Visual Studio

Visual Studio will supported by the .NET Micro Framework 4.3 SDK.

#34783 Introducing GoBus 1.5

Posted by awaiK on 07 September 2012 - 05:31 AM in Netduino Go

Hi, congratulations for releasing GoBus 1.5. Honestly, I didn't pay GoBus much attention in the past, so I'm might be not up to date. But nevertheless I think, the document needs a (little) introduction which describes what's the purpose of the GoBus protocol is.
