SPI

Channel9 : NFC library for all Windows Embedded platforms on Coding4Fun

Cattura_thumb[1]

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!

Channel9 : SPI bus and .Net Micro Framework on Coding4Fun

channel9

Quoting the words of Greg Duncan, I’m a "friend of the blog"!

The weekly Friday post on Coding4Fun blog on Channel9 refers to my article on the SPI bus and its use with the .NET Micro Framework (on Netduino board).

It 'a pleasure to be there !

uNFC library : NFC with the Windows Embedded platforms

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 ...

.Net Micro Framework : SPI, the high speed serial bus !

The SPI (Serial Peripheral Interface) bus is a synchronous communication bus typically used to transfer data between a microcontroller and an external device (eg sensor, actuator, memory, SD card, ...). Being synchronous, unlike the typical asynchronous serial communication (UART), it uses a clock signal to ensure the perfect synchronism in the transmission and reception between the two counterparts known as master and slave. Bus description Overall, the SPI bus is characterized by the following signals : SCLK (Serial CLocK) : clock for synchronization in the data exchange; SS (Slave Select) : signal for enabling the slave (receiver); MOSI (MasterOut / SlaveIn) : data line used for the transmission from master to slave; MISO (MasterIn / SlaveOut) : data line used for the transmission from slave to master; Excluding the SS signal, which can be handled separately, the bus should be considered a 3-wires bus. The master is responsible f ...
