Devices Profile for Web Services (DPWS) may be what you are looking for.

In Topic: NP2 vs. Arduino

Next difference - Arduino Uno R3 has ICSP pins (6 pins near onboard LED) while Netduino Plus 2 has 10 tiny holes there (next to onboard button). As far as I know, the USB Host Shield uses that. Maybe Chris can comment on this difference.

Chris -- thanks for info about IOREF. Actually my shield does not have IOREF pin (see pin layout)

 

I was affraid to turn on AnalogInput with this shield, but you encouraged me :)

For the 16x2 LCD Shield and a code like this:

AnalogInput buttonPin = new AnalogInput(Cpu.AnalogChannel.ANALOG_0);while (true){    Debug.Print(buttonPin.Read().ToString());}

I'm getting:

  • Left: 1.00 (3.85V)
  • Down: 0.97 (3.18V)
  • Up: 0.72 (2.34V)
  • Right: 0.36 (1.19V)
  • Select: 0.00 (0.01V)
  • no button pressed: 0.77 (4.72V)

Voltage measured using multimeter at the same time. Values may differ a bit between readings. Netduino powered only via USB cable.

 

When I connected additional 9V battery voltage raised a little bit: 3.31V for down, 3.91V for left and Read method returned 1 for both buttons.

I've got similar background :-) I have both Arduino Uno R3 and Netduino Plus 2.

The main issue is that Uno has 5V I/O whereas N+2 has 3.3V I/O. In digital mode they are compatible - N+2 can stand 5V and 3.3V is HIGH on Uno. But watch out when you are using analog (especially inputs) on N+2.

For example I had this is a problem when using 16x2 LCD Shield buttons - there is one analog input for 5 buttons and each button causes some known voltage drop. When no button is pressed, there is 5V on A0. In theory you may damage N+2 this way, but some guys on this forum tried that and said N+2 can stand 5V. But still some buttons will not work.


In Topic: N+2 flashing woes - DfuSeDemo crashes

20 February 2013 - 09:38 PM

I had similar problem when upgrading to 4.2.2.2 using DfuSe Demo v3.0.3 on Windows 7 64bit SP1. Tried both 64 and 32 bit DfuSe versions. Download phase goes to 100% and immediately on next phase application crashes. DfuSe Demo also crashes on Verify. Suprisingly, after such crash, detaching and attaching Netduino, NETMF detected it. I was able to change MAC address, deploy and run some simple app.
