#60599 Help with recreating an Arduino project into Netduino

Posted by Chris Walker on 02 November 2014 - 04:11 PM in Netduino 2 (and Netduino 1)

Hi Tinymacrocosm,

Pullups are disabled on OutputPorts and AnalogPorts automatically. Although OutputPorts do automatically drive their signal voltage high/low--so if you don't mean to do that then open everything as an InputPort (or TristatePort) with pullups disabled to start with.

Welcome to the Netduino community,

#60598 Impossible to use System.Net

Posted by Chris Walker on 02 November 2014 - 04:09 PM in Netduino 2 (and Netduino 1)

Hi Desable783094,

Are you using an Ethernet shield with your mainboard? Netduino 1 doesn't have System.Net or networking onboard...but we have some experimental Wiznet drivers if you want to use the System.Net classes with the Arduino Ethernet shields or compatible.

Hi Pete,

Do you have a logic analyzer (to make sure that the data is actually flowing through)?

Also, did you happen to instantiate your SerialPort object in Main and then let it go out of scope by exiting the Main function? Or something that could cause the garbage collector to clean up the object and/or its DataReceived event?

#60596 Serial only works when plugged into USB N+2

Hi rickitytick,

If you plug in external power while also using USB power from your PC, does the Netduino app run fine?

If you reset that board while Visual Studio is not running, does the Netduino app run fine?

Plugging in external power should auto-switch from USB power. The thing I'm looking for here is to find out if it's a power issue, a timing issue, etc.

#60584 Netduino Mini 2 being designed?

Posted by Chris Walker on 30 October 2014 - 04:29 AM in Netduino Mini

Hi David,

Nothing to announce today. We do have a NETMF port for STM32F401 which we're using on some of our IoT maker gear, but it didn't quite meet our requirements for a "Netduino Mini" style MCU. We are keeping the little guy in mind though; Netduino Mini is pretty awesome for miniature projects.
