This time Creg Duncan had to give more than usual explanations to justify the very first constant presence on the Coding4Fun blog!
“Today's Hardware Friday post is another project from our Friend of the Blog, Paolo Patierno (yeah, yeah, I know, it seems like I'm posting his stuff all the time, but hey, it's cool stuff) !”
I'm glad that my "small" open source projects had quite successful and this is the time of uNFC library that implements support for the NXP PN532 NFC chip for all Windows Embedded platforms (from. NET Micro Framework to Windows Embedded 8 passing Windows Embedded Compact).
About this library ... tomorrow it will be featured at the Microsoft Embedded Conference in Naples in a demo on Smart Home & Smart Factory System!
As always .... it is a pleasure to be there!
After the previous two articles describing the SPI and I2C buses and their use with the .Net Micro Framework, it is now finally time to see a practical application with my latest project available on CodePlex : uNFC – NFC library for .Net platforms ! Introduction : software and hardware support This library allows to use NFC integrated circuit connected to your PC (via serial) or to embedded system based on Windows Embedded Compact or .Net Micro Framework. It supports all three types of .Net Framework : .Net Framework 4.0 for PC based on Windows 7 / 8 or embedded systems based on Windows Embedded Standard 7 and Windows Embedded 8 Standard; .Net Compact Framework 3.5 / 3.9 for embedded systems based on Windows Embedded Compact 7 and Windows Embedded Compact 2013; .Net Micro Framework 4.2 and 4.3 for embedded systems like Netduino boards and .Net Gadgeteed boards; The library supports NXP PN532 chip but it also defines a little framework so that y ...
At the same as SPI, analyzed in a previous article, the I2C (Inter-Integrated Circuit) is a synchronous communication bus used to connect and exchange data between a microprocessor and external devices; it was developed by Philips, now NXP, today it is "de facto" standard. Bus description The I2C bus is also known as two-wire as it is characterized in all the effects of only two "wires": SDA (Serial Data Line) : line for the data transfer; SCL (Serial CLock) : clock for data exchange; The lines abovelines are always characterized by a pull-up resistor that has the task of maintaining the signal "high" (logic 1) in conditions of idle while the interconnected components (master and slave) have the task of lowering the level to transfer a logic 0 and release it to bring it back to idle and transfer a logic 1, this behavior is typical of the open-drain lines. Similarly to SPI, you can have multiple slaves connected to the bus and a single master to communicate wit ...
