These two methods are not equivalent. The last one only Reads once. Did you mean something like this instead, which is definitely way too verbose?

I think you missed the last line inside the loop since you tried to assign a bool to a delegate

So get a shot of reality here, Chris last post was just 6 days ago...

/irony?

The issue at hand is no word from anyone representing "Secret Labs", it makes people uneasy. It is a really bad course of action given the state of NP2.

If performance is not an issue, you can adapt from http://code.google.c...Packets/Xtea.cs or the public domain implementation found on wikipedia. I'm sure you can find other c# implementations that don't use unsafe code too.

The way that is coded it checks only once. To get the behaviour you want(check on each iteration):

public static void Method_6()
        {
            while (phcontroller.Read() && method_state_6)
            {
                ph.Write(false);
                Thread.Sleep(1 * SecondMs);
                ph.Write(true);
                Thread.Sleep(5 * MinuteMs);

            }
}

or +verbose:

public static void Method_6()
        {
            while (phcontroller.Read()==true && method_state_6 == true)
            {
                ph.Write(false);
                Thread.Sleep(1 * SecondMs);
                ph.Write(true);
                Thread.Sleep(5 * MinuteMs);

            }
}

or ++(really unnecessary)verbose:

public static void Method_6()
        {
            bool phState = phcontroller.Read();
            while (phState == true && method_state_6 == true)
            {
                ph.Write(false);
                Thread.Sleep(1 * SecondMs);
                ph.Write(true);
                Thread.Sleep(5 * MinuteMs);
                phState = phcontroller.Read();
            }
}

To be honest, I think you should study a good c# book before moving forward with your project... your questions are language/logic related. Don't let the difficulties discourage you, gather more knowledge and when you succeed it'll be even more gratifying.

No problem
in that case you can create the variable outside the scope of the method.

static bool nutrientState = false;//initial value
public static void Method_7()
        {
            nutrientState = phcontroller.Read();//read the port and assign result to nutrientState
            while (nutrientState == true)//run until nutrientState is set to false            
            {
                a.Write(false);
                Thread.Sleep(5454);
                a.Write(true);
                b.Write(false);
                Thread.Sleep(3000);
                b.Write(true);
                Thread.Sleep(5 * MinuteMs);
            }
        }

Here it is a static class member and you can set it to false somewhere else. Of course if you set nutrientState to false while it is performing the stuff inside the loop, it'll complete it first and then check nutrientState - if this is not the behaviour you want, you must take a moment and rethink how to implement your logic.

You can't create static members in the scope of a method. If the compiler/vs doesn't let you, you are probably wrong...

This does what you want:

public static void Method_7()
        {
            bool nutrientState = phcontroller.Read();
            while (nutrientState == true)            
            {
                a.Write(false);
                Thread.Sleep(5454);
                a.Write(true);
                b.Write(false);
                Thread.Sleep(3000);
                b.Write(true);
                Thread.Sleep(5 * MinuteMs);
            }
        }

phcontroller.Read() is a method call and returns a bool. nutrientState stores the value returned. When you compare it in "nutrientState == true", phcontroller.Read() is not called again, the value stored in nutrientState is used.

Note that the way it is coded, the loop will run forever until the thread is aborted.

So for example if I am interested in this:
STM32F051R8T6 ARM Cortex-M0 32-bit microcontroller with 64KB of Flash memory

1) it is not enought to run netmf

2) if I want to develop on that cortex-m0 my only option is to buy expensive compiler suite + ide, for example Keil has the free limited to only 32kb. The first option is the "basic" @ 2000euros

correct?

so with netmf I spend a little more on CPU (Cortex M4 is 7$ for 1000pcs), but I save huge on IDE+tools?

1) correct

2) wrong. You can go with the free and open alternative: gcc toolchain for arm + openocd + eclipse cdt. Just takes a little more work and knowledge to get things up and running. There are also other free "bundles", such as CoIDE(http://coocox.org/)

really...........why such atrocity?

Internet is not in this equation really. Like you said, all it takes is to be connected to the same access point, so you can connect to its local network address. Internet can be seen as an upperset of your local network.

So you basically want an web server running on your Netduino http://forums.netdui...h__1#entry20317 + http://forums.netdui...h__1#entry23532

Congratulations, Netduino Plus 2 is awesome! One thing I really liked is the power control circuitry for external peripherals. I also think it would be cool if you could squeeze in a buck regulator instead of the LDO to convert VIN_PROTECTED to 5V, thus allowing higher VIN. If you guys can perfect the firmware, exposing most of the MCU peripherals while compiling with GCC, this board will be a real winner in the NETMF world IMO.

Hi, you can erase the board and program it using ARM or Thumb instruction sets, but of course you have no access to NETMF. To be honest you should start with a simpler 8-bit microcontroller or use an emulator software for educational purposes...

Instead of using 2 relays, you can use transistors to build a simple logic gate http://www.electroni...ic/logic_2.html http://www.electroni...ic/logic_6.html

Do you get any response at all? "Common status codes include: 200 OK: request processed successfully. 401 Not Authorized: either you need to provide authentication credentials, or the credentials provided aren't valid. 403 Forbidden: Cosm understands your request, but refuses to fulfill it. An accompanying error message should explain why. 404 Not Found: either you're requesting an invalid URI or the resource in question doesn't exist (eg. no such feed). 422 Unprocessable Entity: Cosm was unable to create a feed because the EEML/JSON was not complete/valid (e.g. it didn't include a "title" element). 500 Internal Server Error: Something went wrong... Please post to the forum about it and we will investigate. 503 No server error: usually occurs when there are too many requests coming into Cosm - if you get this from an API request then the error message will be returned in XML in the response." https://cosm.com/docs/v2/

IMO, Netduino should provide One-Wire support in the standard firmware instead lol

In any case, if you still have problems you can use linear regression for calibration.

You should also make wider power traces and if you are making it 2-layer, make a Vcc plane/pour to make routing easier and reduce noise.

Hi Paulo, can you post what circuit are you using? Do you have an appropriate resistor between the port and the led? P.S.: "Tension" is voltage, they are interchangeable terms in portuguese, although "voltagem" isn't well accepted among professionals...

You guys have it way too easy, try being a geek in Brazil

Given that your program knows when it is turning lights on or off, it's just a matter of storing what you did and when you did. If you know 100% sure that netduino will be working uninterrupted, you can probably use DateTime.Now and figure how to work your requirements out. Otherwise, you should consider getting a RTC chip with some memory+battery...

200mA is the maximum ammount of current the microcontroller I/Os can draw(Page 14 http://www.atmel.com/Images/6120s.pdf) The maximum current on the 5V rail depends on what voltage you are feeding the board with, but in general you should be ok with up to 800 mA. It pretty much depends if you are able to sink the heat dissipated.(http://www.onsemi.co...l/MC33269-D.PDF)

Hi, if you want minimal part count maybe ds1722 will work better for you. It's also cheaper..

Heey Mr. Vernari thanks for your response. Yes, I am using Arduino(Ardupilot)system. EZ1-Ardupilot-3.3V battery. It works really fine with the USB port connection 5V and yes I have 4 different 3.3v batteries brand new but for any unknown reason, when I connect the 3.3v on it, the ultrasonic conversion leads to significant errors. Noise. Any Ideas, I know it is weird.

Follow the datasheet's instructions to calibrate the sensor and adjust your code to take this into account:

AN – Outputs analog voltage with a scaling factor of (Vcc/512) per
inch. A supply of 5V yields ~9.8mV/in. and 3.3V yields ~6.4mV/in.
The output is buffered and corresponds to the most recent range data.
