arduino mega ethernet shield tft display factory

If it is the official Arduino Ethernet Shield, you can probably fit a 6-way IDC ribbon connector onto the 3x2 male pins at the back of your display and then attach the wires to digital#51, 52, 53 on the Mega2560. I would solder the ribbon wires onto some real male header. This will give a good electrical connection to the MEGA2560 female header.

As you have realised, no one can really help unless you say which 7" TFT and which pins it uses. Are they in conflict with the Ethernet Shield"s pin usage?

My idea is to use only one SDCard, de Ethernet Sd card would be the one to use for everithing. So the question is how to connect (by wiring) the TFT to the arduino board, and know if i have to make any changes on tft configuration to disable de microsd to not cause any conflict with the microsd ethernet card.

When I try adding any code for the SD card (card inserted into the Ethernet shield slot), it initializes the SD card, but can"t find the Ethernet shield. If I remove the SD card, it obviously can"t find it, but the ethernet shield works.

I suspect this has something to do with the various chip selects. Some posts say the ethernet CS is on pin 10, others refer to 53 for MEGA. I tried both, no luck.

ok so i own a arduino mega 2560 with a 3.2 tft touch screen and LCD shield, recently just bought a Ethernet shield and connected to the mega and ended up with a white screen... if i remove the Ethernet shield, then the tft will display like normal... any idea why i am getting this white screen when the Ethernet shield is plugged in?

i haven"t defined the Ethernet shield but i don"t think it matters as the tft is all connected together as a stack anyways, So even if the Ethernet is not being used... wouldn"t the tft still displays?

Open "WebServer.ino" in Arduino IDE, and add code in the program to define the IO connection between W5200 shield and UNO (For other mainboards, please revise according to actual IO connection), create a W5200 shield init function "DF_W5200_Init" and place it in setup for calling.

}Revise IP address (please make sure that the modified IP address is in the same network segment as the computer and is not occupied by other devices.). For example, set W5200 shield IP as: 20.20.1.177, then the codes should be revised as below:

In this article, we will see a list of useful Arduino Shields, a special hardware that sits on top of Arduino and gives additional features to Arduino. I collected a list of unique and useful Arduino Shields which are mostly compatible with Arduino UNO.

Arduino Shields are add-on boards than can be plugged on top of an Arduino board and provided additional capabilities and functionalities to an Arduino Board. They have the same pin position as an Arduino Board and are usually designed to implement a specific function.

While it is easy to play around with Arduino by placing components on a breadboard, it is not a preferrable option to design a final product with breadboards.

With the help of Arduino Shields, Sensor Boards and other expansion boards, you can significantly reduce the complexity of the wiring the circuit and at the same time reduce the build time and construction process.

NOTE: The images shown here are just for reference. Actual product may vary. Also, there are several manufacturers of a single shield. So, features may vary between shields from different manufacturers.

Perhaps the simplest of Arduino Shields is the Prototype Shield. It comes with a prototyping area, on which, you can solder the components, if necessary.

If you do not want to solder, then don’t worry. The shield also comes with a 170 Pin Mini breadboard, which can be attached on the prototyping area with the help of double-sided tape.

As the name suggests, an IO Expansion Shield allows you to connect several Analog and Digital IO devices to the Arduino without breadboard and soldering. There are headers for connecting 3-pin and 4-pin sensors. You can select the supply voltage for sensors between 3.3V and 5V.

If you are beginner, then the Multifunction Shield is a must have expansion board for Arduino if you want to quickly start programming without worrying about wiring the circuits. It contains 4 LEDs, 3 Push Buttons, a 10 kΩ Potentiometer, a Piezo Buzzer as the basic IO devices.

Also, there is an on-board 4 – digit 7 – Segment Display connected through two 74HC595 ICs to drive them through serial communication. There are also interfaces for LM35 Temperature Sensor, DS18B20 Temperature Sensor and IR Receiver.

One of the popular Arduino Shields is the LCD Shield. It is built around the famous 1602 Character LCD (16×2 LCD Module). It contains a 16×2 LCD Display with White characters and Blue backlight. The shield also contains 6 Push Buttons of which 1 is the Reset button and the other 5 are for user application like LEFT, RIGHT, UP, DOWN and SELECT.

The LCD is connected to Arduino through pins D4 – D10 using 4-bit mode. You can also control the backlight (D10). Another beautiful implementation is the way the 5 push buttons are connected using only one Analog IN pin.

If you want to build robots and cars using Arduino, then a Motor Driver is an important component. Fortunately, there are several Motor Driver Shields for Arduino to reduce design time and complexity. The most popular one is the L293D Motor Shield. As the name suggests, it contains the famous L293D Motor Driver IC.

The expansion board consists of two L293D ICs and a 74HC595 Shift Register IC. Using this shield, you can connect 4 DC Motors (up to 12V) and two Servo Motors (5V) at the same time. To power the motors, there is a connector for providing external power supply.

Controlling Robots and RC Cars with a Joystick is a fun little project on its own. A Joystick Module is a tricky one as it is not breadboard friendly. So, using a Joystick Shield on top of your Arduino Board changes the “game” completely (pun intended). There are several types of Joystick Shields but the one I present here is a complete package.

If you want control mains powered devices using Arduino, then you use a Relay Module in your project. A Relay Shield is an Arduino Expansion Board consisting of 4 Mechanical Relay Modules with four dedicated terminal connectors for each relay.

A 4×4 Keypad Matrix consists of 16 Push Buttons arranges in a matrix of 4 Rows and 4 Columns. Each button can be mapped to a character or a value. To simplify the interface, you can use the 4×4 Keypad Shield.

To incorporate Touchpad in your Arduino Project, you can use the Capacitive Touch Pad Shield. It consists of 9 Capacitive Touch Pads interface through MPR121 IC, Proximity Capacitive Touch Sensor Controller.

If you are building a Robotic Arm or a Hexapod Robot with lot of Servo Motors, then the next Arduino Shield is just for you. It is a 16-Channel, 12-bit PWM Servo Shield for Arduino.

This Shield is based on PCA9685, an I2C based PWM LED Controller. So, in addition to controlling the Servos, you can also drive LEDs with PWM Signals.

Using a GSM/GPRS Shield, you can connect your Arduino Board to a GSM Network. The GSM/GPRS Shield allows you to make / answer calls, send / receive messages (SMS), connect to internet through GPRS.

Some of the common applications of GSM/GPRS Shield are Home Automation, Industrial Automation, Agriculture / Irrigation Automation, Vehicle Tracking, Remote Monitoring and Control.

HC-05 Bluetooth Module is a very popular communication modules for Arduino. There are Arduino Shields with Bluetooth Modules on then to enable Bluetooth Communication over serial interface.

Another popular shield in the Arduino Community is the Ethernet Shield. This particular Ethernet Shield is based on W5100 Ethernet Controller from Wiznet. Connect an ethernet cable to the RJ-45 Jack and you can control Arduino from the Internet.

The impact of ESP8266 on DIY Community is immeasurable. It is a small module with built-in Wi-Fi for wireless connectivity of Arduino. The combination of Arduino and ESP8266 is a major contributor to the DIY IoT Projects. There are Wi-Fi shields for Arduino to easily integrate ESP2666 (or any other Wi-Fi Controller) to an Arduino Board.

No need for soldering or breadboard as this Wi-Fi Shield simply plugs into an existing Arduino Board and communicated over Serial Interface. There is also a microSD Card slot on-board for data storage.

The VS1053 MP3 Decoder based MP3 Shields for are Arduino are a great way to add Music touch to your DIY Project. The VS1053 MP3 Decoder IC is an decode several audio formats like Ogg Vorbis, MP3, AAC, WMA, MIDI.

VS1053 MP3 Player Shield also consists of an microSD Card Slot so that it is easy to store and play audio from an SD Card. There is a 3.5mm headphone jack and the shield communicates with Arduino over SPI Interface.

This is a fun little shield to a small colour display to Arduino. The Colour TFT Shield consists of a 1.8” TFT LCD screen with a resolution of 160×128 pixels. This particular display is controlled by ST7735 TFT Driver IC which can display 18-bit colours.

A Touchscreen Module is a great addition to your Arduino Project. A TFT Touchscreen LCD Shield is the easy way to start with touch screen. Although touch screen modules come in various dimensions, a 2.4” LCD is quite popular.

This LCD supports a resolution of 320×240 pixels. There are many LCD Controllers but SPFD5408 is a popular one. The shield also contains a microSD card slot.

Adding a microSD Card to your Arduino Project can be very useful in data logging and other similar applications. A microSD Shield enable you to add a microSD card to your Arduino Board.

Often used in automobiles, CAN bus is an industrial bus used for long distance, low speed data transfer. CAN-Bus Shield is designed around MCP2515 CAN Bus Controller with SPI Interface.

Every CAN Controller requires a CAN Transceiver to convert the single ended data lines to differential data lines. This particular CAN-Bus Shield uses MCP2551 CAN Transceiver IC.

The Xbee Shield for Arduino is a great way simplify the process of adding Xbee Modules to your Arduino Project. These shields are designed to support different wireless networks like Zigbee, Bluetooth Low Energy, IEEE 802.15.4, etc.

A GPS Shield with Data Logger consists of a GPS Receiver Module and a microSD Card Slot on-board. The GPS Module interfaces with Arduino over serial communication while the microSD card is connected to the SPI Pins.

You can implement speed monitoring, position tracking and other similar application using a GPS Logger Shield and an Arduino UNO board. There are several GPS Modules like GP3906, Neo-6M, REB-4216 etc.

PN532 NFC Controller based NFC/RFID Shield is a perfect board for adding 13.56 MHz RFID or NFC functionality to your Arduino applications. The shield is compatible with SPI, I2C and SPI Communication interfaces.

As the name suggests, an USB Host Shield gives your Arduino board USB Host capabilities. This USB host shield consists of all the digital and analog circuitry to enable full-speed USB peripheral/host with your Arduino UNO.

The MQ2 Gas Sensor is a very useful module to implement safety related applications. An MQ2 Smoke Sensor Shield will be perfect for your Arduino Board to detect Smoke, LPG, Carbon Monoxide and other toxic gases.

Digital FM Radio Shield for Arduino enable you to listen to FM stations using your Arduino Board. You can digitally control the stations, receive Radio data system (RDS) information like artist song and read the strength of the signal using this shield.

If we want a long distance, no interference and reliable communication, especially in noisy industrial environment, then RS484 is the best choice. A fully isolated RS485 Shield for Arduino can be used for professional application as it provides galvanic isolation between the RS485 Bus and the Arduino.

This Shield is based on ISO3080, a fully isolated RS485 Transceiver. There is support for full duplex RS-422 (4-wires) or half-duplex RS-485 (2-wire) data transfer.

Addressable LEDs are awesome. Whether it is an Arduino project or a new PC build, adding LEDs with customisable colours is always a delight. NeoPixel, a brand of Addressable LEDs (based on WS2812B) from Adafruit, are very popular RGB LEDs in the market.

It contains 40 RGB LEDs arranged in a 5×8 matrix. You can daisy chain these shields but remember that these addressable LEDs are RAM hungry and an UNO board may run on low RAM.

Even though it is considered an antique protocol, the MIDI Communication Protocol allows you to control music synthesizers, sequencers, samplers and other music related devices. Using a MIDI Shield you can build Arduino based MIDI Interface System.

The shield consists of MIDI IN and MIDI OUT ports. There are two potentiometers that can be configured to control volume, pitch, tone etc. The shield also has three push buttons for additional functionality.

If you want to add power backup to your Arduino Project, then Energy Shield is the way to go. This shield is based on LiPo Battery power shield, which will charge the battery if external power is available but switches to battery power in case the external power is disconnected.

There are multiple ways to power the shield like solar panels, USB and DC Jack. The shield also acts as a power bank to charge other 5V devices like mobile phones, MP3 players etc., through the USB port.

Interfacing camera with a Microcontroller board like Arduino is always a challenging task as the camera is a memory intensive module. But the Camera Shield for Arduino by ArduCam simplifies this task with a easy to use camera and simple user interface.

This article gave an overview of some of the commonly used Arduino Shields in the DIY community. This list of Arduino Shields is quite small compared to plethora of shields and expansion boards available in the market. I will add more shields in the future.

I just purchased Seeed"s TFT Touch Shield 2.0 for Arduino, but I cannot seem to figure out how to access the SD card while maintaining the ability to draw to the screen. The tutorials and documentation are quite insubstantial (for me), and most questions on the product site seem to be directed to the same wiki page, which doesn"t explain anything about the SD interface, other than what example file draws bitmaps from the card.

I"ve used the SD interface with the Ethernet Shield before, but it"s been a long time since then, so I can"t quite remember the ins and outs. From my old code, it seems that, for normal usage of the SD library, you simply do:

What I assume is happening is that pins 11 through 13 are set to input for some SPI-related reason, the TFT chip select "enabled" mode is set to HIGH, and then the screen is subsequently enabled. Serial moniter is started, followed by SPI, and then the TFT. After those things happen, it does something unknown to me, starts the card, and then uses the standard card initialization method. It finishes up by preparing to draw the bitmaps and sends this "command 0x2c", which is used frequently in the underlying libraries to "start to write to display ram".

The problem is that I have tried initializing the TFT and SD card using this code, and then attempted to draw graphics as shown in my second example, but this did not work. I need to be able to read bytes from the SD card, and then be able to draw simple graphics on-screen, and repeat.

So my question is: Is anyone who has used this shield before or has experience with this able to explain how one should go about writing the code to allow usage of both the SD card and screen or how the initialization and SPI processes work to make this possible?

I successfully manage to get ethernet shield and TFT shield to work individually. Then since TFT shield will not be able to use the ICSP interface I connected the jumpers as it says on wiki.

After this I put everything together and try to get them working with the below code but for some reason I don"t know, Ethernet shield stopped working. I get the error Ethernet shield was not found. Sorry, can"t run without hardware. :(. Even though the error, my TFT screen lights up and runs demo. Probably I"m missing something simple. I"ll appreciate any help or guidance.

Using this TFT LCD Mega Expansion Shield V2.2 for Arduino MEGA the users can now directly plug the LCD shields from 3.2″ to 5″ onto the Arduino Mega board.

TFT01 LCD works in 3.3V so that it can not be used directly on top of the Arduino motherboard, in order to make the TFT01 LCD compatible use with the Arduino board. Designed this section TFT Shield, it can be directly plugged into Arduino board Using the TFT01 LCD module.

The TFT01 LCD is now supported 16-bit mode, it will not exist encounter like in 328S, only using a set of SD card interface or touch screen interface for Arduino Mega256.

This article describes the use of the Deek Robot design for an ethernet card. This design uses a 74HCT08 to ensure that the levels on MISO and Interrupt fully meet the spec of the 5V Arduino, but there are considerations:

2) The buffered signal on MISO cannot also be connected to another shield (such as a CF shield) because it is permanently actively driven by the HCT08.

3) The “\INTPT” output of the ENC28J60 is buffered to Arduino Digital Pin 2 for use with INT0. This digital pin cannot be used by anything else and MUST be set as an input.

2) If another MISO must be interfaced, connect it to pin 5 or 4 of the 74HCT08, not to the pin on Arduino. The ’08 will then buffer both signals. THIS IS VERY DELICATE!

Second: I am using it and after a few hours the device stops sending data to another server I have. kind of a buffer overflow at the ethernet card, just a feeling. I restarted it and it does fine for a few hours more, then the same.

First thing to check of course if both Arduino and PC have the right IP address (fixed?). An IP address is required since we’re working over a network, even if it’s just a cable from the ENC28J60 to your computer.

For example, I’ve downloaded the ethercard zip, opened Arduino 1.5.6-r2 and imported the unzipped folder library. After restarting the IDE, I select any Ethercard example, but it doesn’t compile**

I have been using the EtherCard library a while and wanted to switch to the UIPethernet library but could not make it work. I suspected the reason to be in different pinning connection but till I found this article have not had any luck finding the pin-connection used by UIPethernet.

I have used ethernet and arduino for maybe 4 years now. It’s quite simple to pull a web link lIke google.com into the arduino, but more complex links seem to be too difficult to get around. I’ve already forgotten the steps that need to be taken to obtain the ip address for “google.com”, but once I’ve sort of re-learned that process, I’d like to be able to pull in other Web pages, like: http://www.marinetraffic.com/en/ais/details/ships/538005277/vessel:BOW_CONDOR

I picked up an ethernet board today. I’ll try to tweak the “web page reading” files a bit. The second group of code above has a line: client.print ….. sometimes syntax has, sort of, a beginning quotation mark after the GET in that client.print statement (or so I thought). But it’s been so long since I’ve tried to dig into this stuff. I probably should know this syntax, but I don’t really. I have to travel for work, so if I don’t reply for like 3 weeks, or whatever, I’ll try to be back here at a later date once I get more time off from work. I may check back here for like the next 2 or 3 days, but then I have to go back to work for like 16 days. I’ll be back here sometime.

I have recently bought a MEGA 2560 to replace my UNO – primarily due to the UNOs limited memory. The EN28J60 board works fine with UIPethernet but when I hook it up to the MEGA using the same pins as on the UNO it does not work. I have a TFT touchscreen with SD cardreader attached to the MEGA but I don’t believe there could be bus-/dataconflicts.

Thus I added pin 10 as SS for the SD card reader, set it as output and HIGH, waited 5 ms before communicating on the SPI bus with the Ethernet board and it worked.

Unfortunately, I do not have my equipment with me (I’m traveling), but I did find some articles that might help (I did a Google search on “arduino parse html form”):

Iam also using an rfid reader and arduino mega adk with ethernet shield connected to a raspberrypi (lamp server). I had build a local access control system for 1 door but now ive added 2 more doors and the verification of rfid tags needs to be more centralized.

Did u had any luck with the parsing of http form ? Iam thinking from the arduino mega a http get request via php and then in the page returned a string compare of the scanned id tag with the ones returned from mysql (allowed ones).

I think if u had any luck with ur project it will give me a boost. Iam also looking of MySQL Connector/Arduino http://drcharlesbell.blogspot.gr/2013/10/introducing-mysql-connectorarduino-100.html

As for the MySQL connector: for a Uno this library might be too big, not leaving much space for other code. A Mega should be able to work with it though.

Its very interesting project and i enjoy working on it. I have ID20LA RFID Reader and also u need a breakout board. The reader is working without any problem for many months. I also bought a typical electric strike (12V DC) connected with a 5V excitation DC relay from digital pins of arduino (important: not directly cause the excitation of the coil can return current back to arduino and destroy the board).

You’re also correct i started the project with a uno rev3/poe ethernet shield and the code without using mysql connector was about 29k of 32k that uno has. The mysql connector needs at least 15k.. so last week i bought arduino mega adk and port my existing code there.

I want to make it work using http

get and parse the results for my UNO, but also using QUERY_POP from arduino mysql connector for mega. I have a local xampp setup for easy testing (a mysql database called door1 with a table tag and columns id, name, event_date) so iam in the phase of trials and errors :D

The Arduino Data Push article get’s you started with passing info to the server (MySQL), you’ll just need to combine it with receiving an answer from the server

I am using Wireshark to sniff the computer ethernet interface, and when I try to connect to the arduino, loaded with any of the examples, like TcpServer, all I see is the ARP request for the ip I gave to the arduino board, but no answer. I guess is due to my board, everybody else seems to be enjoying the code. Is there anything to change anywhere to make it work with arduino mega boards? Thanks!

I have this board http://www.dx.com/p/ethernet-shield-v1-1-for-arduino-66908 which stacks on top of the Mega board. The problem was as said by Robert the different pins used for SPI, but also because on Mega pin 13 goes to control an onboard LED. So, I cut the DI/O pin 13, correctly connected pins (10, 11, 12, 13) to (53, 51, 50, 52) without changing anything else, it worked smothly.

Thank You for Your answer. I check it and contains print() function (not println()). However this is other library and is not connected to UIPEthernet.

Netbeans is much more complex to setup to work. However I use it to build program and then load it by AVR-ISP to boards made by me (and using same MCU as Arduino). This is not possible by Arduino IDE (as I think).

My project works well with EtherCard Library. But now I ‘m trying to use UIPEthernet library by your recommendation with no success. Where can I change the CS pin? I can’t find it!

I’m planning the automation of my home:solar power, alarm, watering garden, lights and so on. A problem is length of wires. SO my idea its to have distributed arduinos with Ethernet shields, so its necessary that these mini-modules works as client-server. They can be able to receive instructions as”turn kitchen ligth ON” or say to the server “window opened -> fire alarm”

LEDs not blinking on the RJ45 can mean issues with the network cable, but since you had it working with an Arduino Uno, I think we can rule that one out.

I haven’t tried the Arduino Nano yet, but as far as I recall from the comments, is that pin 53 is intended for the Arduino Mega. I assume you made a typo.

Power could be an issue, but if the same power supply was used as with the Arduino Uno, then I would think it’s adequate for the Arduino Nano as well.

I would think the ENC28J60 should be nano compatible. I’ve used it with an Arduino Uno R3 and Nano and Uno seem the same (expect the Nano has 2 more analog ports it seems) – see Arduino board comparison chart. According to the info on the Arduino website, the Uno and Nano use exactly the same pins for SPI. Same power requirements/levels, same microprocessor, same memory, same clock …

Thanks for this article, I was trying to run your Nano v1 Ethernet module with an Arduino Nano v3 and did not work … everything was so simple with the explanation of “Not the same driver WIZnet 5100 with ENC28J60” and download the libraries everything worked. thanks for the info.

One maybe helpful post I found at Github (Can arduino_uip work with ATmega644 – I know it “sounds” irrelevant, read through the conversation there and you’ll see they are talking about changing particular pins in the library code).

After reading this article I decided to do some tests with the various libraries listed here. My personal take is that Ethercard by far wins on performance and flexibility. UIPEthernet suffers from multiple problems, including hangs.

2) Does the first Arduino library mentioned (ETHER_28J60.cpp) implement a TCP/IP stack? I know the EtherCard uses the tuxgraphics tcp/ip stack, and that uipEthernet uses Adam Dunkels famous uip stack. (Incidentally ibex has lots of great open source projects, including a tcp/ip stack for the enc28j60 : http://www.embedded-code.com/source-code/communications/ethernet-tcp-ip/ethernet-tcpip-driver )

5) Do you have any thoughts on the Lantronix Xport (ethernet <-> uart) modules? Do they work the same as the enc28j60 but use rs232 instead of spi? I’ve seen some videos for it and it seems to work without any extra code on the embedded side! Not sure though.

I want to connect a ENC28J60 ethernet to my GBoard Pro (Itead) with GSM. I need it to be able to plug a IP Camera to the Ethernet, and that it uses GSM to send n Picture Taken to the FTP server.

C:\Program Files (x86)\Arduino\libraries\etherShield/ip_arp_udp_tcp.h:32:77: error: ISO C++ forbids declaration of ‘progmem_s’ with no type [-fpermissive]

C:\Program Files (x86)\Arduino\libraries\etherShield/etherShield.h:34:76: error: ISO C++ forbids declaration of ‘progmem_s’ with no type [-fpermissive]

I need to use enc28j60 and NRF24l01+ via SPI, but there are some problems in libraries. I found many comments on Arduino forums about this but it was two years ago. First solution is to use Mirf library, but it’s less convenient than standard RF24 library. If anyone could help or can point me to important things about this please tell me about. Thanks!

I am trying to make this work with Arduino Mega 2560 and ENC28j60 using the UIPEthernet library (latest release and/or forks) to run one of the Arduino Shield examples (“Web_Params”), replacing relevant includes with “#include ”. The problem I am facing happens during compilation, here is a bit of a stack trace I get:

Webduino is considered to be a great high-level library (e.g. for creating RESTful APIs) and is listed on the official Arduino page. You might find it useful. Although it does not support the ENC28J60 chips, that’s why you need a wrapper such as UIPEthernet to make it work. I read this article where author mentions using them both (I am going to post this question there too):

A quick glance on the articles you’re referring to, gave me the impression that the code was written to try several ethernet/wifi modules. Maybe the author overlooked this, or … an older/newer version of UIPEthernet changed.

/Users/john/Documents/Arduino/libraries/UIPEthernet/utility/Enc28J60Network.h:99:8: warning: #warning “Not defined ENC28J60_CONTROL_CS. Use borad default SS pin setting. You can configure in ‘utility/Enc28J60Network.h’.” [-Wcpp]

/Users/john/Documents/Arduino/libraries/UIPEthernet/utility/logging.h:24:2: warning: #warning “You can configure LogObject and ACTLOGLEVEL in ‘utility/logging.h’. More verbosity more memory usage.” [-Wcpp]

Second point, you wrote “I opened Enc28J60Network.h file and tried to add my ethernet chip“, it is not custom to edit library files – unless you really know what you’re doing. So please do not edit library files – you’ll have to do everything in your sketch, and should never have to edit any of the library files. To undo your changes, unless you know exactly what line you modified, please reinstall UIPEthernet. While you’re at it, consider downloading the latest version from Github.

3. My arduino ide is uploading the code but nothing happens on the serial monitor (baud is set accordingly) or in browser ( i looked in my router software to see if any new ip connected to my local lan)

/var/folders/bd/pzwcmknd3bd_c10t4kwkq_hc0000gn/T/arduino_modified_sketch_641225/HelloWorld.pde:28:41: warning: deprecated conversion from string constant to "char*" [-Wwrite-strings]

by the best of my knowledge, Ping depends on the library implementation since the hardware is super limited when it comes to the stack implementation (hence it’s lower price tag I assume). Not sure if the UIPEthernet library even supports this (even though I’ve found it to be one of the best out there for the ENC2860).

The library DOWNLOAD – ETHER_28J60 and Ethershield doesn’t work. Already at the first compiler run an error occurs the a function in not correct declared :

Did you properly install the Arduino IDE (you did not mention the platform you’re running – eg. Windows/Mac/Linux)? Running it from your Downloads directory may cause issues. Another issue is that the library is old and no longer maintained; “prog_char” is no longer used, it is now “const char *progmem_s” – Consider using UIPEthernet as it may be the better choice.

Result: It drops done to 2.2V at my “China Arduino Nano” if I connect the shield. Therefore I used an original Italian one. Result: 3.08V which should be in the range of the 28J60 Chip

Do to the fact, that the shield still doesn’ t work with the 3.08V, I swapped the shield. Now this shield is working fine with the library UIP-Ethernet. But in contrast the Ethercard library doesn’t work, although I used Pin 8 for Chip-Select.

Glad you gad something to work – yeah the voltage difference can be a pain, especially with clone Arduino’s (there are more problems with some of the clones).

If I’d be doing something with networking, I may consider starting with one of those ESP8266 boards (on it’s own, and not as a shield for an Arduino).

I replaced the shield, that means the left one on your figure 2. With this, I can also use the small library “Ethercard” without problems. This shield has an voltage regulator which supplies the ENC28J60 Chip with 3.3V from a 5V input. Now for me I have to work on the EMC protection of the Arduinio circuit, because I use it to control and configure a radio transmitter.

Configuration: Arduino Nano clone + ENC28J60 Ethernet Shield for Arduino Nano 3.0 RJ45 Webserver Module (V1.0) + Nano I/O Sensor Shield Modul for Arduino UNO R3 Nano V3.0

Problems accured, when I wanted to use the D2 for a digital input with interrupts. As there were no schematics for the ENC28J60 Ethernet Shield, it took me some time to find out, that the D2 is used as interrupt-line for the Ethernet Shield. Even if it is not used, it pulls the level to High.

hello…:)…i am newer to arduino ..and i want to do a project with em18 reader and hr911105a 18/20 ethernet using arduino nano…i have done with my code…when i put card on em18 reader it sends to the server but always response false but against the card no i have code the ok response…please help me….

I’m not familiar with the “hr911105a 18/20”, but if you’d like to see an example on how to pull or push data with the shield used in this article, then please check out these articles:

Im settup a remote way of reading voltage and current via ethernet using Nano Every and Deek Robot ethernet shield ( ENC28J60) and the UIPEthernet library.

After lost of strugling and swearing (I’m totally new to Arduino’s!!) I’ve eventually go it to act as a web server buy disconnecting pins D8 and D10 between the 2 and taking pin 8 from the Nano Every to pin 10 on the shield.

The shield sits below the Nano so all pins are connected through and what I’ve done is bend Nano pins 8 and 10 out at 90 deg so they don’t plug in. Then a jumper from Nano Every pin D8 to D10 on the shield and that works.

I have found reference in posts about the other library’s (that are no longer supported!) for this shield about being able to change the CS pin on the NANO to suit the shield but can find nothing for the UIPEthernet library!

Trying to find an answer, I did find this post on the GitHub page of UIPEthernet. It’s a little messy, but it seems that there may be a trick that could work for you.

After installing and looking at the files: in the directory for the UIPEthernet library, there is a subdirectory called “utility” which holds the file “Enc28J60Network.h“.

I’m not sure if this will work (never tried it on an Arduino) and we may have to glue and “if” around it, for cases where SPI_CS wasn’t defined to begin with (but then the simple “#define SPI_CS 8” would have worked right away). This could look something like this:

Being unable to dig into it at the moment (about to walk out of the door), but before calling Ethernet.begin(), you may be able to call Ethernet.init(PIN);.

Well the good news is that worked and I’ve now got the shield on top of the Nano Every with all pins connected and even a I2C display connected and everything works….

Arduino Uno is the most popular Arduino board so far, however it is sometimes frustrating when your project requires a lot of sensors or Leds and your jumper wires are in a mess. The purpose of creating the Base Shield is to help you get rid of bread board and jumper wires. With the rich grove connectors on the base board, you can add all the grove modules to the Arduino Uno conveniently! The pinout of Base Shield V2 is the same as Arduino Uno R3.

5-Power Switch: when using Arduino UNO with Base Shield v2, please turn the switch to 5v position; While using Seeeduino Arch with Base Shield v2, please turn the switch to 3.3v.
