From the Secret Labs (makers of the family of Netduino board), a very interesting project funded through Kickstarter: AGENT smart watch, a watch "intelligent" completely based on. NET Micro Framework! The initial goal of $ 100,000 has been largely superseded even share reaching $ 1 million! Ten times higher than the target set! But what this product promises, whose distribution will begin at the end of 2013 for all those who have participated in the financing (the "backers")? Managed Runtime As anticipated, the AGENT is completely based on. NET Micro Framework (version 4.3) with all those who are the advantages for developers in managed code (eg C #), but mainly related to the development environment that is obviously Visual Studio 2012 ! Hardware : double processor, LCD and sensors Since applications developed for the smart watch may require more power, the AGENT has a Cortex-M4 to 120 Mhz to which, however, was accompanied by a second processor (an AVR, much reduced) in such a way that the primar ...

Since I loaded my small MQTT client. Net Framework (Desktop, Compact and Micro) on CodePlex, I have never posted a simple example of the use of time for questions. In this post, we shall see how it is possible to realize a "simple" alarm system consists of two boards Netduino Plus both connected in the network, through the first board we are able to detect a movement through the use of a PIR (Passive InfraRed) sensor while the second is capable of receiving the notification of the detection (in this case does is to write it on the console Debug). Obviously, the second board may be trivially replaced by a smartphone through which we could be alerted in real time of the intrusion. Regarding the broker, it is the simple RSMB (Really Small Message Broker) of IBM which can be used in a totally free for non-commercial purposes and downloaded here. You do not need to install it but, in the case of Windows, is a simple executable to be launched in order to have a broker and MQTT listening on the default port (1883) ...
I have just posted a new little CodePlex project: M2Mqtt.
It is a MQTT client (Message Queue Telemetry Transport) that can be used on all .Net platforms, obviously focused on. NET Micro Framework.
MQTT is a protocol for M2M (Machine to Machine) as part of the Internet of Things and for which lately has been a process of standardization by OASIS. Suffice it to say that thanks to his remarkable "lightness", was chosen as the protocol for the exchange of messages through the Facebook Messenger.
For further information please refer to the official website MQTT but I will not fail to publish as soon as possible a series of articles related to this protocol and to the use of the library that I just released.
I recommend .... stay tuned!
This time on Channel9 there is the project of Duke Nukem gas sensoring with .Net Gadgeteer that makes use of my client ThingSpeak included in uPLibrary. I'm obviously happy to see that my "little" work can always be helpful to others and to be recognized as valid and working .... hopefully! Should serve you, remember that it is always available on NuGet!
The project on the weather station that I have already published on CodePlex is the subject of one of the blog posts Coding4Fun on Channel9, as always managed by Greg Duncan.
It just been officially announced on the Netduino forum the release of the new version of the base of the SecretLabs boards : the Netduino 2 ! After the release of the second version of the board that has Ethernet connectivity and microSD onboard, the Netduino Plus 2, the entry-level version board has a successor even more powerful. Microprocessor and memory Following the same line of Netduino Plus 2, the microprocessor is completely different from that of its predecessor, in fact it is a STM32F2 (from STMicroelectronics) based on architecture Cortex-M3 to 120MHz in place of an Atmel ARM7 to 48 Mhz. The jump of memory is amazing! The amount of available RAM is 60 KB and for Flash the amount available to our application goes from 128 to 192 KB. Input and Output The board provides 22 GPIO pins (compared to 20 above), part of which have the following features: 6 PWM; 4 UART; SPI interface; I2C interface; In addition, there are 6-channel ADC with a resolution of 12 bits (rather tha ...
uPLibrary, dedicated to. NET Micro Framework, which I started developing for over a year and upgrade over time with new features has been reported on Channel 9 in Blog Coding4Fun thanks to the efforts of Greg Duncan at the following link.
The version 1.9 of uPLibrary is enriched with another managed driver for the management of an anemometer, an instrument used for measuring the wind speed. The driver is generic, considering the common operation for most of all anemometers. The anemometer I used generates 4 pulses per second to the detection of a wind speed of 10 Km / h; such information is useful to determine the true wind speed by counting pulses in a time interval that can be set. In fact, Anemometer The class provides a constructor whose parameters are the following: inPin: Pin board used and it is connected to the output signal pulse anemometer; calculatePeriod: period in which the driver must observe and assess the wind speed (the default value is 5000 ms); referenceWindSpeed: reference wind speed in km / h (the default is 10); referencePulseForSecond: number of pulses per second reference (the default value is 4); As you can see the default values of the driver are those of the anemometer used for testing ...
Beginning of the year ... the uPLibrary grows and upgrade to version 1.9 ! One of the new features added is the managed driver for the temperature and humidity sensor SHT1x of Sensirion, which is available in a convenient breakout board of DFRobot. The communication protocol is expected to be a non-standard I2C, so the .Net Micro Framework classes dedicated I2C are unusable. In this case, the only solution is the bit banging, through which the date and clock signals are driven directly by software. The implemented class SHT1x provides a constructor which pass the two pins used for the aforesaid signals over the power supply voltage supplied to the sensor. The latter information is necessary for the implementation of compensation formulas for the calculation of the actual value of temperature and humidity from the data read from the sensor. The methods exposed are trivially as follows: ReadTemperature (): provides the measured temperature, on the basis of the unit of measure passed as a parameter ...
I’m pleased to introduce you my new open source project on CodePlex…..Net Micro Framework Weather Station !
This project helps you to build a weather station based on .Net Micro Framework. The data come from some sensors (temperature, humidity, luminosity and wind speed) and you can read them, in real time, using a Web page on the integrated Web Server. Enabling data logging, you can save your data into a microSD.
The project is built for Netduino Plus board and based on .Net Micro Framework 4.2 but you can use a different board changing only the pin for the sensors connections.
It uses Metro UI CSS (http://metroui.org.ua/) for Metro style Web page.
