Here's a project that uses a Netduino-based motion sensor to trigger video captures on a Windows 8.1 tablet or laptop (http://channel9.msdn...D-motion-sensor)

Hello,

I've installed the 4.1.1.0 beta firmware on a Netduino board and tested with a simple app to ensure that it's working. (Blinking LED...)

Next step was to add an RS232 shield and test HID firmware that's already running on a Netduino Plus. I attached the shield and used a USB/RS232 cable [with FTDI chipset] to deploy the firmware. However, the deploy fails and times out. The error I see is: "Unable to communicate with device - Serial: COM4".

Just to verify that there wasn't an issue with the shield or cable, I reattached the same shield to a Netduino Plus and deployed. This worked without any issue.

Has anyone else observed similar issues with RS232 shields and the Netduino?

Thanks!

I've attached an LM35 to both a Netduino and a Netduino Plus. The readings fluctuate unexpectedly on both boards.

The attached screenshot shows three columns of data: The first is the value retrieved from the AnalogInput.Reading method; the second is the temperature in degrees Celsius; the third is the temperature in degrees Fahrenheit.

These readings were taken when the LM35 was sitting on my desk in a room that's showing 75 degrees Fahrenheit on a digital thermometer in the same room. (The readings are within an acceptable range--but--I don't understand the fluctuations.)

Has anyone else observed this with the LM35?

Thanks!

Microsoft released an end-to-end sample for Windows 8.1 that uses a Netduino-based motion sensor. The sample Windows app (included as part of the solution) triggers 5 seconds of video-capture when the motion-sensor detects movement. Here's a link: http://code.msdn.mic...sensor-39bea694
