arduino mega ethernet shield tft display free sample

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….

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?

I"ve never much liked to walk. If you"re in the same boat then you should learn how to update your Freetronics EtherTen and Arduino Ethernet-based boards over the network. In an amazing coincidence this step-by-step guide will teach you how to do just that thanks to the wonders of a protocol called the Trivial File Transfer Protocol or TFTP.

When you"ve completed these steps you will be able to upload your sketch over a network to an Arduino-compatible Ethernet board. You will need to manually specify the IP address of the board and use a couple of small command-line tools to upload your sketches.

From the perspective of your Arduino the approach documented here (arduino-tftpboot) is a "push" approach - you decide when you want to update the sketch, then tell your Arduino to accept a new program (i.e. you "push" a new sketch to the Arduino). An alternate approach is a "pull" approach where your Arduino automatically checks to see if it needs to update its sketch every time it is powered on or reset (i.e. the Arduino "pulls" a new sketch from you). We do not cover the "pull" approach here: if you are interested you should check out the arduino-netboot bootloader instead.

The approach documented here should work with any combination of Arduino-compatible boards/shields that use an ATmega328 microcontroller and WIZnet network Ethernet interface. You can let us know in the Freetronics forum if you find a combination which doesn"t work - patches also welcome!

If you have an EtherMega or other non-ATmega328 board this method can in theory also work for it but we don"t cover how to do so here as modifications to the bootloader are required.

A network that supports static IP addresses. If you want your board to acquire its IP address automatically you need a bootloader that supports DHCP. The arduino-netboot bootloader supports DHCP but is more complex to set up and we do not document the process here.

The solution we present here (arduino-tftpboot) is based on the Perotto variation of the TFTBootloader which is itself based on the TFTBootloader release from the Arduino team. (Why did we choose the Perotto variation? Because (a) it works; and, (b) it"s released.)

The first step you only need to perform once per Arduino IDE you want to use to burn the bootloader. The next three steps you will only need to do once per board you wish to make TFTP-upload compatible. The fifth step you will need to follow each time you want to change the sketch on your Arduino. The final step is only required once per sketch you want to make remote-reset compatible (so you don"t have to manually reset the Arduino to receive a new sketch).

Remember, the approach we document here is the "push" option: you control when the bootloader is run and "push" a file from your computer to your Arduino.

First up you need to install the "platform package" that contains the bootloader you will burn to your Arduino to make it TFTP-compatible. This also contains a library with some tools and helpful examples you can use later on.

Move the hardware folder from the unzipped package into your Arduino sketchbook folder. Note: If you already have an existing hardware folder in your sketchbook folder then you can just move the arduino-tftpboot folder into it instead.

(Optional) If you want easy access to some helpful tools and examples then also move the ArduinoTFTP folder from the libraries folder in the package into the libraries folder of your Arduino sketchbook.

Verify you have the platform package correctly installed by looking for a new board named TFTP Bootloader ATmega328 (No Upload) available under the Tools > Board menu:

Select the Tools > Burn Bootloader menu option. This will burn the arduino-tftpboot bootloader to your board. It can take around a minute for this to complete:

Immediately after the bootloader has been burned it will blink the LED at a rate of about once per second until you upload a sketch via TFTP. Once a sketch has been uploaded the LED will only blink for about three seconds after a reset/power-on (indicating the bootloader is waiting for a TFTP connection) before it stops and the uploaded sketch is executed.

With the bootloader installed you can now decide what network configuration your Arduino will need. Our next step will help you choose the configuration you need for your network.

Have you ever tried to help a friend or family member troubleshoot--over the phone--a problem they"re having with their computer? It"s pretty difficult--especially if you can"t see what they"re seeing. Trying to help you configure your network and Arduino in written documentation is a little like that.

By the end of this step you will know the network addresses your computer and your Arduino each need in order to be able to communicate with each other. In addition you will have stored the settings so that the arduino-tftpboot bootloader and your sketch can use them.

The arduino-tftpboot bootloader only supports a "static" IP address--it cannot use DHCP to acquire an IP address dynamically each time your Arduino is powered up.

If you connect to your network via WiFi (most likely with a laptop) I recommend you first try to work with your Arduino directly connected to an Ethernet network port on your computer. Once you know this works properly you can then change the configuration to work with your main network. Following this approach delays being concerned about other network configuration issues until you know everything else works. See the "Direct link-local connection" section below for the simplest way to set this up.

If your network uses static IP addresses then you can ask the network administrator for a static IP address for your Arduino. (If your network administrator is yourself then make sure you have a well reasoned argument ready before you ask yourself.)

If your network uses DHCP then you either need to ask your administrator for one or more static IP addresses to be allocated or investigate using the arduino-netboot bootloader which can use DHCP--but isn"t documented here. If you are your own network administrator you can often configure your network router/DHCP server to never allocate a block of static IP address which you can then use--but how to do that configuration is outside of the scope of these instructions.

On many operating systems when a DHCP server cannot be found on a network connection the OS will fallback to using a link-local or "self-assigned" address. For example, by default on Mac OS X when you connect a device directly to the Ethernet port this approach is used. Here is the view on Mac OS X of the Network panel of the System Preferences application when a self-assigned IP address is used:

When using a link-local connection your Arduino needs to have an IP address which begins with 169.254. I generally cheat and use an address of 169.254.254.169 which being palindromic is easier for me to remember. If you don"t suffer from this affliction then you can choose a different address in the range of 169.254.[1-254].[0-255]. The reason this is cheating is because your Arduino should check that noone else is using the same address first. But hopefully the computer you"re connecting to is better behaved.

You can keep the default bootloader value for the MAC address. You will need to change the net mask to be 255.255.0.0 in order to be compatible with link-local addresses. If you want your computer to act as a "gateway" for your Arduino you"ll need to set the gateway address value to match the IP address of your computer (which will be difficult if it changes each time you connect--so depending on the link-local implementation your OS uses this method is less suitable if you want your Arduino to have outgoing network access).

If your Arduino is to be connected to a network (via a router, switch or hub) and not directly to your computer (via a link-local connection) then you need to determine a suitable static IP:

If you have a network administrator then--when you request a static IP address--the administrator should provide you with the static IP address, a netmask value and the gateway address you need to use. You should ensure that you are not using the same MAC address as anyone else on your network--a clash is only likely to occur if someone else is using an Arduino on your network. If you are part of a school or other institution you should ask what the policy is for allocating a MAC address for an Arduino on the network. Armed with this information you can now move on to the "Storing your network settings" section below.

If you"re using a home network you can probably get away with looking at your own computer"s IP address and then adding, say, 50 to the last digit of the address. e.g. if your computer"s IP address is 10.1.1.4 then try using the address 10.1.1.54 for your Arduino. Also, in most cases, you can probably get away with using a netmask of 255.255.0.0--even if it"s not strictly correct.

If you want your Arduino to be able to access the internet you will need to also supply an IP address for your "internet gateway" (most likely your modem/router). Your Arduino will use the same gateway IP address that your computer does--you"ll need to look at your computer"s configuration to determine the correct address.

As long as you only have one Arduino on your network you can use the default bootloader MAC address. Otherwise make sure you, say, increment the last digit of the default MAC address by one for each Arduino you add to your network.

Next you will learn how to store these settings so both the arduino-tftpboot bootloader installed on your Arduino and your uploaded sketches can use them.

The arduino-tftpboot bootloader has the ability to read network settings from EEPROM and use those settings rather than its defaults. First, though, you need a sketch to store the network settings in EEPROM. But once you have installed the bootloader you can"t upload a sketch to it unless it has the correct settings! It ends up being a bit of a chicken-egg situation.

There is an additional complication due to the fact the default Arduino bootloader configures the Arduino so the EEPROM is erased when a bootloader or sketch is uploaded via an ISP programmer. This means the settings in EEPROM will not be preserved if we write network settings to EEPROM from a sketch before we install the new bootloader.

The way this works is that the first time you burn the bootloader it also configures your Arduino to preserve the contents of the EEPROM whenever you next burn a bootloader or sketch. But when you upload the network settings sketch via the programmer it also overwrites the bootloader. So, then you have to burn the bootloader again but this time it will preserve and use the settings in EEPROM. (Yes, it"s frustrating repetition but it seems there is no easier way.)

(Optional) If you have a serial connection to your Arduino board you can check that the EEPROM has the correct values by uploading the eeprom_read sketch via your ISP programmer (File > Examples > EEPROM > eeprom_read) and verifying the values it prints to the serial monitor. The output should look something like this:

Once the arduino-tftpboot bootloader is installed on your Arduino again you will need to verify your Arduino"s network settings and then you can upload a sketch over the network. You"ll learn how to do this in steps four and five, which are coming up right about....now.

Before you upload your first sketch over the network you need to confirm that the network settings for the Arduino, bootloader and your computer are correct. Let"s do that now!

You will need to use a "wall wart" or similar power adapter to supply power to your Arduino board - connect that now. If you are using a switch - or injector - that provides Power-over-Ethernet you will not need a separate power supply. For testing purposes you can also use the power from the USB connector or programmer.

If you intend to connect your Ethernet-capable Arduino directly to your computer (which you will do if you"re using a link-local connection) then you can use an Ethernet cable to connect from your computer"s Ethernet port to the Ethernet port on your Arduino. The Ethernet chip on the Arduino (and in most computers) is smart enough to work out there"s a computer on the other end so there"s no need to use a special "cross-over" cable).

If you intend to connect your Arduino to a router, switch or hub then you can use an Ethernet cable to connect from a Ethernet port on the router/switch/hub to the Ethernet port on your Arduino.

When you connect the Ethernet cable, one of the LEDs on the Ethernet connector on the Arduino board should be lit steadily to indicate a "link" has been established to the router/switch/computer while the other LED should blink to indicate traffic on the connection. (On an EtherTen the green LED shows the "link" is connected, while the orange LED represents "traffic" on the link. The colours may be different on other boards.)

Start a Terminal, shell or command line session (the name differs on each operating system) and instruct your computer to contact your Arduino with (by default):

You can use Ctrl-C (or Control-C) to interrupt the ping command when you want to stop the response or if the display shows no response other than something like this after a few seconds:

While the Arduino IDE will compile our sketch for us as normal, we need to know where the IDE puts the compiled file. To do this we need to enable "verbose compilation output":

If you have connected an LED an resistor to pin 9 you can open the File > Examples > ArduinoTFTP > BlinkUploadTest sketch. (Otherwise you"ll need to choose a different sketch with which to test.)

Due to the way the bootloader works we need to convert from the compiled file format the Arduino IDE produces to a format the bootloader can understand.

The conversion uses the avr-objcopy tool from the avr-gcc package--this is distributed with the Arduino IDE on Windows & Mac OS X but needs to be installed separately on Linux distributions. avr-gcc may also be installed separately on Windows or Mac OS X but in most cases it"s best to use the version that ships with the IDE.

As you might expect tftp on each operating system works a little differently, so when the instructions below say "start the sketch binary file upload" this is what you will need to do:

Ensure you are in the same directory as the BlinkUploadTest.bin file you created earlier. (This is required because tftp on OS X does not appear to support directories when specifying the name of the file to upload.)

Your distribution may or may not ship with a tftp tool installed by default. If tftp is not installed you"ll need to use your package manager or other tool to install it.

The key issue is that the bootloader and your sketch need to be consistent with their use of MAC address and IP address. For example, if the bootloader uses a particular IP address and your sketch uses the same IP address but a different MAC address things will probably grind to a halt. (You can verify this by pinging your Arduino and if it responds while in the bootloader but not when your sketch is running that may be why.)

Ideally there would be a library function that can automatically configure your sketch with the same settings as the bootloader but such a thing has not been written (feel free to contribute something). In the interim there is a modified version of the standard Ethernet library"s WebServer example sketch which you can use that includes a function to read the IP address from EEPROM.

Once you can upload a sketch over the network you may start to think you also need a way to remotely reset the Arduino so you don"t need to walk over to the board to press the onboard reset button. We need to reset the Arduino in order to start the bootloader so it is ready to receive the sketch over the network.

An Arduino has what"s known as a watchdog which monitors whether or not it is operating in a correct manner. If the watchdog has detected the Arduino has hung (i.e. it"s unresponsive) it will reset the Arduino into the bootloader. We can use this functionality to trigger the reset remotely--by intentionally "hanging" the Arduino.

Your web browser will display an error message but in a couple of seconds your Arduino will reset and the bootloader will be active for a few seconds.

It"s possible for your sketch to malfunction in such a way that you cannot connect to it over the network to force a reset--so don"t put your project in a box, throw away the key and have no way to reset your Arduino manually.

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.

TFT displays are now very cheap to get and are also popular in the Arduino community. The start is often a little difficult, but with the right library it is easy. The display has a resistive touch screen with a good accuracy. This example shows how to create switches (eg F-Keys), or generate error messages as well as question pop-ups. The main screen should show a user-friendly interface with some values, a system status as well as the time (system runtime). The buttons F1-F4 can be operated via the touch screen and display various demo examples. To use this example, you only need an Arduino as well as a TFT display and the corresponding library.
