In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

Whatever you are currently celebrating, Christmas, Hanukkah, Jul, Samhain, Festivus, or any other end-of-the-civil-year festivities, I wish you a good time! This December 25th edition of the Nextion Sunday Blog won"t be loaded with complex mathematical theory or hyper-efficient but difficult to understand code snippets. It"s about news and information. Please read below...After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.

On models with a HDMI video output, you can connect to a touch monitor to enable full control over the application, or to a large-screen television for displaying KPIs, trends, or other process data in your facility. Supports full HD resolution (1080p).

Maple Systems HMIs communicate with any device that uses the Modbus ASCII protocol and originates ASCII messages as a master device. The HMI uses the MODBUS ASCII Slave protocol driver, to configure the HMI as an ASCII slave in a point-to-point single master, single slave, or a single master, multiple-slave format. RS485 networking is supported to connect multiple MODBUS slave devices (HMIs) to a single MODBUS master device.

Provide feedback to the HMI operator with audio alerts for alarms and button presses. Audio alerts can also be controlled by the PLC or with the macro function.

An alarm can be configured to not only display a message on the HMI screen in an Alarm Display, but also playback an audio alert to notify the operator of the alarm condition.

BACnet is a communication protocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5 standard[1] protocol and is supported in our HMI series.

Connect an Android phone or tablet equipped with a camera and the cMT Viewer app to a cMT Series HMI. The Android camera can scan 1D or 2D barcodes and the data will be written to the designated addresses.

Touch gestures can trigger various actions such as change window, set bit, set word, execute macro, popup window, keyboard input, and screen hardcopy. Triggering a sequence of actions using a single gesture is also possible.

When cMT Diagnoser connects to an HMI, it immediately begins to monitor objects in the current window; furthermore, it can make the HMI screen change to another page.

When debugging a macro, cMT Diagnoser provides line-by-line debugging and displays the values of the trace function output as well as all the declared variables.

The Combo button allows multiple actions including set bit, set word, change window, and execute macro to be performed with a single press of a button. It also displays the state of a bit or word register.

Enable time synchronization in the HMI via an NTP (Network Time Protocol) server so that the HMI real-time clock will periodically synchronize to the date and time on the NTP server. The HMI can also be configured to automatically adjust to daylight savings time.

When downloading a project to an HMI, you can select the option to "synchronize HMI clock with PC." This will copy the date and time settings on the PC into the real-time clock of the HMI.

This option is configured in the System Parameters Model tab in EBPro. When this option is enabled, the HMI will read the date and time from the PLC that it is connected to on startup and copy it into the HMI"s real-time clock.

An option to use a custom bitmap that is displayed while the HMI initializes enables you to advertise your company logo or contact information every time your HMI powers up.

The Set Word object provides two operation modes: manual or automatic. Manual mode can change the value in a designated word address when the object is touched. In automatic mode, the word register is automatically activated when a pre-defined condition occurs; touching the button will not be effective.

The Set Bit object provides two operation modes: manual or automatic. Manual mode can trigger a designated bit address to change the state between ON and OFF when the object is touched. In automatic mode, the bit is automatically activated when a pre-defined condition occurs; touching the button will not be effective.

The Combo button allows multiple actions including set bit, set word, change window, and execute macro to be performed with a single press of a button. It also displays the state of a bit or word register.

Dynamic Drawing object enables drawing a shape in a specified region on HMI screen at run time. The shape can be a line, a rectangle, a circle, or a dot. By setting the Attributes Addresses, the style and the color of the shape can be customized.

Traditionally, HMIs were designed to connect only to local industrial control equipment such as PLCs or automation controllers. But the ever-increasing need for internet connectivity on the plant floor brings an increased demand for remote access to local HMIs and PLCs.

Accessibility from devices outside the plant provides the opportunity to add new features to the Maple HMI/PLC by qualified personnel without ever leaving company headquarters. The ability to troubleshoot and reconfigure an HMI or PLC from a remote location greatly reduces the length of down time, travel, and personnel costs.

Similar to instant messaging software such as Skype, Facebook Messenger, or WhatsApp, EasyAccess 2.0 allows you to instantly communicate with your HMI without spending time memorizing the HMI"s IP address, or configuring complicated port mapping. As its name implies, EasyAccess 2.0 makes remote monitoring and troubleshooting Maple Systems HMIs efficient and easy.

EasyPrinter is a utility that runs on a PC that can be configured to receive data log files, event log files, recipe files, or screenshots from a Maple Systems HMI over Ethernet using the Backup object in EBPro.

EasyWatch allows users to monitor the HMI or the PLC address values via Ethernet from the PC, or to invoke the Macro for debugging, remote monitoring, and controlling. For example, In EB Pro, after creating a Numeric Input Object, you can set its address to LW-10, and set the same address in EasyWatch. The value of LW-10 will be shown in EasyWatch when successfully connecting.

The Event (Alarm) Log in EBPro is where alarms are defined and configured. Alarms can be bit- or word-level and can reference a PLC or the local HMI. Each alarm is configured individually and can be assigned to one of up to 255 categories (for viewing purposes).

File Browser object can display filenames and their directories saved in the SD card or USB disk. Apart from browsing for the files in the external devices, the filenames and the directories selected in File Browser object can be written to the designated address.

Apart from saving the history data from an HMI to your PC by using SD card, USB disk or EasyPrinter, the FTP Server can also do the backup. After downloading a project to the HMI, the FTP Server can be used to backup or update the history data and the recipe data.

Grid Displays a grid of rows and columns in the object. The color of the grid lines can be selected. Auto fit short column (cMT Series Default style) The column width automatically adjusts to the size of the content.

Use the Label Library to create different labels or text for up to 256 different states for one language (96 states if 8 languages are used). Use the Label Library to assign text to objects on their Label tab. Multiple languages can be created for each label with the language displayed determined by system register LW-9134 (language mode).

Use a Word Lamp as a message display by assigning a Label Library to the Word Lamp. Changing the value in the register assigned to the Word Lamp will change the message displayed.

The Label Tag Library feature enables a multi-language environment. When multiple languages are required, users can create the Label Tag Library and then select a suitable label in the project. The project will display the corresponding language in runtime based on the settings. EBPro supports up to 24 different languages simultaneously.

Once the HMI is configured as a MODBUS device, the data of HMI can be read or written via MODBUS protocol. As shown in the following figure, the HMI is configured as a MODBUS device (also called MODBUS Server). The HMI, PC or other devices can use MODBUS protocol to read or write HMI data via Ethernet or RS-232 / RS-485 interface.

To access the data of the PLC connected to HMI with SCADA software (Supervisory Control and Data Acquisition), the former way was to transfer PLC data to the HMI"s local address first, and then use MODBUS TCP/IP protocol on PC to read HMI local address to get PLC data.

Maple Systems Advanced HMIs and Smart X Series HMIs support the MQTT standard version 3.1.1. This allows them to act as either MQTT Brokers (Servers) or MQTT Clients. Typically, HMIs are used as MQTT Clients to publish process data to a central MQTT Server. Commonly used MQTT Brokers, which are supported by both the Advanced and cMT Series include, for example: Mosquitto, HiveMQ, RabbitMQ, and EMQX.

Data is organized into Topics in MQTT. Maple Systems HMIs can publish data either periodically (Time-based) or whenever a value changes (Trigger-based; a.k.a. "Report by Exception").

Any MQTT Client can subscribe to Topics via the MQTT Broker, whether that Broker is running on another HMI, or, as is more often the case, on another PC, Cloud-based Server, or SCADA System. Clients can subscribe to all topics, or just specific topics, from the Broker.

Instead of downloading your project to the HMI every time you make a change to see if it works correctly, you can run the Online or Offline Simulator in EBPro to verify your changes.

With Offline Simulation, you do not need to have the PC connected to the PLC. A simulated HMI screen will run on the PC that shows you how things will look on the HMI as you develop your project. All PLC values displayed in the project will revert to zero or off.

With Online Simulation, connect your PC to the PLC over either Ethernet or a serial port (a USB-to-serial converter can be used with the PC). The simulator will interact with your PLC program and display data just as if the HMI were connected to the PLC. This can save development time since you don"t have to download to the HMI every time you make a change to your project in order to test it with the PLC.

Our HMIs can be configured to operate in Serial or Ethernet Pass-Through mode. In this mode, data being sent from a PC is routed through the HMI to a PLC or controller. The Utility Manager (installed by default alongside EBPro) is used to configure Pass-Through operation.

This can eliminate the need to disconnect the PLC from the HMI when it is necessary to configure either the HMI or the PLC. Pass-through mode is only available on HMIs with an Ethernet port. An Ethernet connection from the PC to the HMI is required to initiate pass-through mode, even when using serial pass-through mode.

The PDF Reader (Smart X Series only) can display a PDF document stored on a USB flash drive or SD card. Multiple documents can be stored on the external drive and selected using the File Browser.

Use the Picture View object to display images stored on a USB flash drive or SD card. This gives you up to 32 GB worth of space enough to store and display the most complicated user manual. Supports *.bmp, *.GIF, *.jpg and *.PNG file formats. For your convenience, a scroll bar for paging through image files is built into the Picture View object.

The Smart Series HMI support combo setting for Pie Chart, which allows setting of multiple related objects at a time. Pie chart can be set with Background and Legend.

EBPro provides Index Registers for changing addresses flexibly. With Index Registers, user can change the object"s read/write address directly on HMI without changing its settings. There are 32 Index Registers, divided into 16-bit and 32-bit.

The selected PPD file is downloaded to the cMT model along with the project file to allow the HMI to send print jobs to a printer connected over Ethernet or USB. Status registers can be assigned to display the printer status and error codes, and command registers can be configured to update the printer status, change the printer interface (USB or Ethernet), and change the IP address and port number.

After editing a project (.emtp), users can compile the project to .exob format. The .exob file can be downloaded to HMI. Password can be set to protect the .exob file when compiling. A password will be required when attempting to decompile the .exob file back to .emtp file.

The Industrial Internet of Things (IIoT) takes data from your factory floor and shares it with a server (local or a cloud service), offering greater efficiency for network use and enabling better access to and better sharing of data for your entire organization. This data can then be analyzed and used to boost profits, improve processes, reduce downtime, and much more. The Maple Systems human machine interface (HMIs) is the perfect device for the edge of network gateway.

Administrator Tools utility and downloading the information to the HMI. In addition, the control registers can be used for managing accounts directly on the HMI such as log in, log out, change password, change classes, and add/delete accounts including temporary accounts (time-limited).

Logging out is accomplished by writing a 3 to the control register or the HMI can be configured to log out a user automatically after a preset number of minutes of inactivity.

MySQL and Microsoft® SQL Server are well supported database options that can be used with our Smart (cMT) series to help collect and display data for easier monitoring and analytics. They also support a built-in database query viewer which enables production machines to retrieve data from your central SQL database.

String table sections hold null-terminated character sequences, commonly called strings. By pre-configuring the texts and their corresponding numbers in the String Table, the text can be changed dynamically on HMI. String Table can also be used in a multi-language environment.

The System Setting Editor is a tool that can be used to duplicate the settings in the System Settings window in the HMI. These settings can be saved as a configuration file (systemsetting.conf) and downloaded to the HMI along with the project file, saving the programmer the time of having to go into the System Settings window on the HMI and configure all the desired settings.

This is especially useful if the programmer has settled on a standard configuration for the HMI system settings. The same configuration file can be used to download to multiple HMIs.

The Text/Comment Object is used to place standalone text on an HMI window. It can be configured to be visible on the HMI screen (default) or to simply leave programming notes in the project that do not show up on the HMI screen.

The text can be manually entered in the Text/Comment Object Properties window or can be linked to the Label Library or String Table. In addition, the visibility of the text on the screen can be controlled by a bit in the HMI or PLC so that the text only appears under certain conditions.

Trend Display (Graphs) Trend Display (Graphs)

Represent complex related data in a simple format using a Trend Display. Display data in real-time with a Trend Display, plotting sampled data (Y-axis) vs. time (X-axis) in graphical format

Display data in real-time with a Circular Trend Display, plotting sampled data (radius) vs. time (circumference) in a graphical format (Advanced HMIs)

Sample Project: Real-Time Trend Display Demonstrates Real-Time Trend Display features including channel visibility, dynamic Y-axis scaling and visibility, and dynamic X-axis scaling.

The HMIs provide the Video Input feature. By installing a surveillance camera, user can monitor the site on HMI. The video images can be stored in external devices and then analyzed on PC. This feature can be utilized in different places for monitoring, such as vehicles or buildings. The following is a comparison table that shows the video input and image capturing behaviors of different models.

Many HMI models support connecting a USB camera to the HMI and viewing the video on the HMI screen. This is useful for monitoring a process or area of the manufacturing floor that is difficult to see from the operator"s position. Now you can log on to the HMI with a web browser via its IP address and stream the video from the USB camera to a PC or mobile device. Simply enable web streaming on the HMI and enter the HMI"s IP address in your browser to view the video.

By connecting an Android® mobile phone with HMI using a micro USB cable, or any USB data cable that is compatible with the phone, the internet connection of the phone can be shared with HMI. On the Android mobile phone please enable USB Tethering.

Customize your project"s start-up screen. Download a .bmp bitmap file to HMI. After HMI is rebooted, this .bmp file will be shown before project starts.

Design: Edit projects, Review the address ranges and formats of supported PLCs, or Simulate an HMI on PC by On-line Simulation (with PLC) or Off-line Simulation (without PLC).

Build Download Data for SD/USB Disk: Build the data to be saved in SD card / USB drive and then insert the device to HMI to download the data. This feature is not supported by the Smart cMT Series.

EasyPrinter, Backup/Printer Server: A backup/printer server on PC, which receives backups from HMI and run a defined batch to convert, or HMI screenshots to print out on PC.

Data/Event log Information: Connect with HMI via USB cable or Ethernet to check the number of history files in HMI. This feature is not supported in the Smart cMT Series.

USB and IP camera video support is included on select HMI models.* This feature allows you to connect a USB or IP video camera to the HMI to monitor your control system on the HMI screen. Monitor Process Status – video for remote operational viewing. Or stream live video of your process to help the operator see areas that are hidden from normal view.

The Media Player object is a powerful audio-visual addition, use it to play videos, show important messages, exhibit crucial warnings, and display advertising. It can also be used an analysis tool for your quality assurance program.

Play sound, video, and animations in your HMI application. Media Player supports the following actions: forward, reverse, play, pause, zoom, next, previous, volume.

In the past integrating this type of equipment with an existing HMI project would mean using complicated protocols and recreating the device"s user interface. Or finding another screen to show the interface on. Now, simply place the PLC Web Browser object and configure it with the device"s IP address. The device interface (or dashboard) is visible on the HMI, seamlessly incorporated into your larger HMI project.

Now you can display information like an OEE (Overall Equipment Effectiveness) dashboard, phone lists, schedules, training manuals or inventory status. Operators now have the information they need right where they need it. Simply point the Web Browser Object to your intranet url or IP address.

Use the HMIs System Keyboard or add an external keyboard to the X Series HMI to allow the user to fill in incident reports, forms, or workorders right from the HMI using the Web Browser feature.

Companies can use their company website, or any website, as the Smart X Series HMI screen saver. This would allow the X Series HMI to become an advertisement for new machines, allowing people who are currently using your machine to see ads for new product offerings.

You can set-up multiple windows in the HMI project that display specific web pages or web servers, and choose to show or hide the navigation bar and add additional security (passwords) to restrict user access to web pages.

With WebView, you simply point your browser to the HMI"s IP address on your local network and log in. Now you have access to all the functions, data, and project screens from your HMI application.

This feature is available on our Smart X Series HMIs. For information on how to implement this feature, refer to the WebView Quick Start Guide or the EBPro Programming Manual. EBPro Programming Manual.

Wi-Fi creates the opportunity to implement high-speed communications with a low investment. The HMI5103L has the ability to connect to an existing Wi-Fi

network and send information to the network without requiring new Ethernet cabling, network drops, etc. This portability means that there is now added flexibility that comes with the monitoring. The HMI connects securely to the Wi-Fi network and uses it to forward requested PLC data.

on their network. Other methods require the HMI and PLC to be on the same network, which can increase overall bandwidth usage exponentially. Keeping the HMI and PLC

monitoring device such as an HMI. Plant corporate networks, of course, can also run via Ethernet and Wi-Fi networking. But how do you get data from the PLC to your corporate network without the bandwidth or security sacrifices entailed by placing your PLC on the same network?

Maple Systems Wi-Fi HMI can connect via Ethernet or serial to your PLC on a local control network, and use its built-in Wi-Fi connectivity to send pertinent

information to users via the plant network. The PLC can transmit everything to the HMI without having to deal with slowdowns or network traffic, and the HMI can maintain a connection to the plant network for VNC monitoring, sending status reports, data log files, and email alarms. In the event of a catastrophic issue causing the main company network to go down, the HMI maintains its PLC connection, which means the machine stays up and running.

For the industrial communications network side, an extensive library of industrial protocol drivers allow the HMI to connect to nearly any PLC on the market. Multiple protocols for different devices and different manufacturers can be used simultaneously, gathering massive amounts of data in real-time, displaying it in a digestible, intuitive way to the plant floor operator.

Log data in the HMI and access it remotely via a built-in FTP server. Log data directly to a computer on one of the LAN ports or send data or alarm logs to a

The HMI becomes a gateway into your control network. PLC and other machine hardware on the control network cannot be directly accessed, greatly improving security

The XY Plot is used to plot one series of values against another series of values on a graph. This provides more flexibility than a Trend Display because one set of data can be plotted with respect to another set of data rather than just as a function of time.

Smart TFT LCD display embeds LCD driver, controller and MCU, sets engineer free from tedious UI & touch screen programming. Using Smart TFT LCD module, our customers greatly reduce product"s time-to-market and BOM cost.
