Have you tried Serial to Ethernet communication?


More than 50 developers tested Wiznet modules during Pizza workshops in Brno, Bratislava and Budapest.

The main topic of Pizzaworkshop was Ethernet communication via Wiznet modules. Developers had a chance to test how fast and simple it is to connect the device to Ethernet and all of this was led by Joachim Wülbeck from Wiznet.Developers also tried working with EVB kits WIZ550S2E, as well as innovative WiZwiki-W7500. There were also answers for many questions about settings, programming, sending and receiving serial data via Ethernet, as well as troubleshooting the proposed applications.

Pictures will tell you more about how it looked like during the workshop… :-)

Do you like our Pizzaworkshops?

Do not miss our next workshop in October with Lantronix. Sign up today. Number of seats is limited.

Arduino Email Sender with Ethernet adapter/shield


by Matej Blagšič @ instructables.com:

My father asked me to do a little project with Arduino that would send an e-mail when a push button is pressed or anything, can be based on temperature reading, so make sure you watch my previous instructable on that or to send that something has closed up on the distance sensor. Be sure to watch those tutorials on my profile.

PIC18 Development Board with Ethernet and USB


by magkopian @ instructables.com:

The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external components. Also, it has 32KB of program memory, 2KB of RAM and it supports an external clock up to 48MHz, which is optional because it also has an 8MHz internal clock.

The ENC28J60 Ethernet controller is used to provide Ethernet connectivity to the microcontroller thought the SPI interface. The ENC28J60 has an integrated MAC and a 10Base-T PHY, 8KB of buffer RAM, supports both Full and Half-Duplex modes and it is fully compatible with 10/100/1000Base-T networks.

Do you also use industrial Ethernet?


Industrial Ethernet enables interconnection among standard office network and industrial environment thus becoming a standard for industrial production.

In presence, Ethernet is most widely spread communication technology in the world. It enables a fast data exchange between all devices connected in the local network.
Thanks to its simplicity, Ethernet standards became the most frequently used network standards. A reason of this popularity is, that they offer a simple technology connected with the biggest network – internet. Advantages of Ethernet and all related concepts are obvious:

  • simple possibility of expansion
  • fast initialization thanks to its connection technology
  • dynamic adjustment of bandwidth (up to 10 Gbit/s)
  • identical network topology for various applications (office and industrial)

Classic system of buses 
Industry and production segment is characteristic by using of buses like: AS-Interface, Profibus, Device-NET and CANopen. They allow to connect a line of sensors, actuators, measuring probes and motors, which can be controlled by a controlling unit. Communication runs down to a level of sensors / actuators. Transfer speeds are up to 12 Mbit / with max. 255 devices depending on a given bus system. Linear displacement with al devices connected in series is dominant.

New possibilities thanks to industrial Ethernet
Industrial Ethernet representsattractive alternative of a classic bus syste. Industrial Ethernet Advantages represented by (producer-independent) are still more used in everyday praxis. Industrial Ethernet brings advantages of “usual” Ethernet into often harsh environment (reliable connectivity, availability and easy expansion). Cables of company Lapp Kabel belong to a top in this segment. We bring you a basic overview of the most frequently used components.

Power over Ethernet Flashlight


by fabiobaltieri.com:

Sometimes you learn about an interesting IC and you build an entire circuit around it for no other good reason… This project is one of those!

The TPS2378 is an IEEE802.3at (Power over Ethernet) Powered Device controller, featuring internal pass MOSFET for loads up to 25.5W, Type 1 (a.k.a. 802.3af) compatibility and auxiliary power source support.

The IC is normally used together with a DC-DC step down regulator to power a network device (the PD) from a PoE compliant switch or injector (the PSE). A proper 802.3at device requires an isolated power supply with some safety characteristics that makes it not trivial to implement, and there are many DC-DC ICs with integrated PoE controller to make it easier, but as I wasn’t really interested in that part I just went for an easier project with just the PoE controller and some ballast… And what better ballast than some high power white LEDs!

Understanding and Using Ethernet-enabled MCUs for Your Next Application


by Warren Miller @ digikey.com:

MCUs offer a very wide range of Ethernet connectivity choices. With most applications demanding Internet connectivity, it’s more likely than not that your next MCU-based design will need some type of network connection. Whether your next design is a sensor that needs to consolidate and communicate data over an Ethernet link, a network-connected security camera that needs to have periodic code updates sent via the network connection, or an industrial controller that needs to use a robust industrial Ethernet connection, your choice of Ethernet-enabled MCU will be critical in delivering the capabilities required for a successful design.

Arduino Network relay

network switch small4

by serasidis.gr:

Remote control your electrical devices through your local network or internet. The circuit contains one output (Relay) and one input (isolated input). The whole project was built by using arduino nano platform and an ENC28J60 ethernet module. It can be used the W5100 ethernet module instead of ENC28J60, by replacing the UIPEthernet library to Ethernet library.

Moreover, the control is made from the Android application I wrote and it’s available on Google Play (https://play.google.com/store/apps/details?id=com.serasidis.NetworkRelay).

The schematic diagram, arduino sketch, photos and demonstration video is on my web site:

Embedded modules may surprise you by their contribution and an overall costs savings.

As we know „embedded module“ is a quite wide term and it can represent a powerful microcomputer with OS, but it can also be a significantly simpler module with a microcontroller and peripherals, still able to add considerable functionality to a target device.

Typical representatives of useful modules, which add a lot – without big costs are so called quick start modules from company Embedded Artists. Their contribution is in a ready-made „tuned up“ PCB containing for example in case of module LPC4088 QuickStart Board (EA-QSB-016) the microcontroller itself (Cortex- M4), memory, display controller and many interfaces like Ethernet, USB, UART, SPI, CAN, PWM, Analog In/Out, I2C, XBee compatible connector and other.

Especially at low and mid-volume production batches their contribution is mainly in the fact, that it is a really proven solution with a guaranteed operating temperatures range, proper ESD protection and mainly – supported by a wide scale of development tools (free). In case of solving of problems, it´s still possible to contact customer support of company and a lot of hints for successful usage, source codes and libraries can be found directly on the producer´s website.

Add Linux, WiFi, Ethernet and USB to Arduino


by Edwin Chen @ open-electronics.org:

The model of this shield named Yun Shield, the feature of this shield is as its name. User can add this shield into Arduino (Leonardo, UNO, MEGA2560 etc) and “turn” the Arduino into device which has similiar features as Arduino Yun: support remote upgrade and use the Bridge library.

With this shield, user can easy to set up communcation between Arduino and Internet (via ethernet , wifi or 3g etc) and add support for USB flash, video. The detail user guide/ manual can be found in the dragino website and most Arduino Yun Sketch / examples can reuse with this Shield. This shield is under production and will be ready within one months time.
