Excuse

Ever have implemented an application to Netduino from a PC, you can?
what happens is that I want to make an application that receives input parameters from the PC (console) and run actions from the Netduino, the Netduino course will always be connected to the PC.

Anyone know, how you could do? because when I create the executable from Visual Studio, not working.

Thank you.

Take a look at this. It may be what you need.

Here is a class for reading & writing INI file from/to Micro SD
It is very simple one... but does the work just fine ;-)
Any feedback will be nice to have.

Here is the source code:

    {
      if (!append)
        DeleteSections();

Thank You..

I was just looking for some of my old code in order to use an ini file.. I will not bother looking further..

Strange.. I was looking for my old code and by chance.. I need to look no further... Yours looks to be more compact than what I remember of mine.

Hi,

Does anyone have a schematic or preferrably a graphical instructable on how to build the circuit to connect up to the EasyDriver, and also connect the stepper motor?

I've seen a portugese tutorial (with no circuit help) and some other code-related examples but nothing for the actual connections...

Thanks!

Not sure if it will help but I found this link.. I do not have the easy driver hardware.

http://www.schmalzhaus.com/EasyDriver/

My solution is to disconnect USB and reconnect.. Mine also.. I have had this problem since day one but I have learned not to let it get to me. Now it is part of the 'fun' of coding the Netduino. I do have to admit that the USB connector on the Netduino is of the best quality based upon the amount of times I have had to unplug and plug it back in ;>). I also have occasional restarting of the Microsoft Visual Express 2010 (Sort of re-boots itself) as in the visual express application closes itself and restarts. It does restart with the Netduino application I was working with. The only thing I know for sure that causes it is having something running in a tight loop as Magpie has noted.

Maybe I am way out in left field for what you want do do? Why not just add a number or message in your Netduino code that is returned to the external application when asked? Yes, you would have to always be sure that this code is included when changing your Netduino's application but it would be simple to implement.
