Arduino Touch Screen Tutorial

Hey guys, its Nick again, welcome to educ8s.tv a channel that is all about DIY electronics projects with Arduino, Raspberry Pi, ESP8266 and other popular boards. Today we are going to take a look at how to use the inexpensive, ILI9325 driver based, 2.8” touchscreen display designed for Arduino and at the end of this tutorial, you should be able to determine if this Touch Screen is a good option for your Arduino projects.

Arduino Touch Screen: 2.8″ Display with ILI9325 driver

I first came across this touchscreen which offers a resolution of 320×240 pixels, and an easy to use micro SD slot among several other great features on banggood.com and decided to buy it for use in some of my projects since it was inexpensive as it only costs around $11.

2.8″ Touchscreen Display

As shown in the video above, we will be performing simple tasks with the display to demonstrate how it works such that, When we press a button on the screen, a message will be displayed it. This means we will learn both how to create a button on the screen such that it can be touched and how to display messages on the screen.

As demonstrated the touch screen is working fine! Finally, we can start building projects with a touch screen which are much more interesting and easier to use.

Required Components/Parts and Where to Buy

The following components/parts are required to build this project and they can be bought by clicking on the links in front of them.

Schematics

The display comes as a shield which makes the connection with Arduino extremely easy, thus all that needs to be done for this project is to plug the display into the Arduino board since we won’t be adding any other sensor or actuator.

Connecting Screen to Arduino

One of the few downsides to this display is that it uses almost all of the digital and analog pins of the Arduino Uno which means when using this shield, we are left with only 2 digital pins and 1 analog pin for connections to other components that the project we are building might require.

Fortunately, this display works fine with the Arduino Mega, so when working on projects with more pin requirements and size is not really an issue, we can use the Arduino Mega instead of the Arduino Uno. Unfortunately, this display does not work with some other Arduino Uno form factor based boards like the Arduino Due or the Wemos D1 ESP8266 board due to pin compatibility and library Issues.

Let’s now see the software side of the project.

Code

In order to use this Arduino Touch Screen easily, we will need three libraries. We will need a modified version of the Adafruit TFTLCD library, the familiar Adafruit GFX library, and the Touchscreen library. All these libraries can be downloaded by following the links below.

Libraries

📥 Modified Adafruit TFTLCD: Download here

📥 Adafruit GFX: https://github.com/adafruit/Adafruit-GFX-Library

📥 Touchscreen: https://github.com/adafruit/Touch-Screen-Library

With the Libraries installed, we can test the display by trying out the examples which came with the libraries. Two favorite examples are the graphicstext example and the tftbmp example whose demonstration can be seen in the tutorial video.

To explore the Touchscreen functionality of the display, I have developed a sample code, which you can extend for use in any of your projects. it can be downloaded via the download link below.

To briefly explain the code, the first thing we do as usual is to include the libraries we will be using.

//////////////////////////////////////////////
  //        2.8" TOUCH SCREEN DEMO            //
 //                                          //
//           http://www.educ8s.tv           //
/////////////////////////////////////////////

#include <Adafruit_TFTLCD.h> 
#include <Adafruit_GFX.h>    
#include <TouchScreen.h>

Next, we declare the pins to which our screen is connected to on the Arduino both for the display and the touchscreen.

#define LCD_CS A3
#define LCD_CD A2
#define LCD_WR A1
#define LCD_RD A0
#define LCD_RESET A4

To use the touchscreen functionality of this display, there is a need for the display to be calibrated. To do this after uploading the code, Open the Serial Monitor and click (touch) on the top left corner of the display and write down the X and Y values displayed on the serial monitor. Then we edit the code to reflect those values. The X value goes to the TS_MAXX variable and the Y value goes to the TS_MAXY variable. We follow the same procedure for the other two variables. We click on the bottom right corner of the display and we enter the values we get in the TS_MINX and TS_MINY variables. With this done our display is now calibrated and ready for use.

#define TS_MINX 204
#define TS_MINY 195
#define TS_MAXX 948
#define TS_MAXY 910

Next, we declare the colors to be used with their hexadecimal values after which we create an object of the Adafruit TFTLCD library class indicating the variables used to represent the pins to which the screen is connected on the Arduino.

#define BLACK   0x0000
#define BLUE    0x001F
#define RED     0xF800
#define GREEN   0x07E0
#define CYAN    0x07FF
#define MAGENTA 0xF81F
#define YELLOW  0xFFE0
#define WHITE   0xFFFF

Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);

We also create an object of the touchscreen library indicating the pins to which the touch part of the screen is connected to on the Arduino.

TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300);

Next, we write the Setup function.

We start the function by initializing the serial monitor and the LCD, after which we set the orientation of the LCD and fill the screen with a black color to serve as the background.

void setup() {
  Serial.begin(9600);
  Serial.print("Starting...");
  
  tft.reset();
  tft.begin(0x9325);
  tft.setRotation(1);
  
  tft.fillScreen(BLACK);

Next, we draw a white frame on the display then set the cursor to the desired location, change the text color to white, and print the “Hello” text on the screen. By following the same procedure, we display the red YouTube text as well.

//Draw white frame
  tft.drawRect(0,0,319,240,WHITE);
  
  //Print "Hello" Text
  tft.setCursor(100,30);
  tft.setTextColor(WHITE);
  tft.setTextSize(4);
  tft.print("Hello");
  
  //Print "YouTube!" text 
  tft.setCursor(80,100);
  tft.setTextColor(RED);
  tft.setTextSize(4);
  tft.print("YouTube!");

Next, we create the red youtube subscribe button. We do this by Creating a red rectangle and for our size requirements, we set the x and y pixel coordinates of the top left corner point of this rectangle to (60,180) after which we define the width for 200 pixels and the height as 40 pixels and set the bottom right pixel coordinates of the rectangle to (260, 220). To make the rectangle look like a button, we then draw a similar white rectangle on the red rectangle and write the “subscribe” text on it.

//Create Red Button
  tft.fillRect(60,180, 200, 40, RED);
  tft.drawRect(60,180,200,40,WHITE);
  tft.setCursor(80,188);
  tft.setTextColor(WHITE);
  tft.setTextSize(3);
  tft.print("Subscribe!");

With the setup function all done, we move to the loop function, the algorithm in operation for the loop section is simple, each time the user clicks on the screen, we convert the point coordinates of the touch point into pixels using the Map function. After conversion, If that point is inside the red rectangle area, it means that the user has pressed the button, so we disable the button by setting this variable to false and we clear the screen so as to display the “thank you for subscribing” message on the screen.

void loop() 
{
  TSPoint p = ts.getPoint();  //Get touch point
  
  if (p.z > ts.pressureThreshhold) {

   Serial.print("X = "); Serial.print(p.x);
   Serial.print("tY = "); Serial.print(p.y);
   Serial.print("n");
   
   p.x = map(p.x, TS_MAXX, TS_MINX, 0, 320);
   p.y = map(p.y, TS_MAXY, TS_MINY, 0, 240);
       
   if(p.x>60 && p.x<260 && p.y>180 && p.y<220 && buttonEnabled) 
   // The user has pressed inside the red rectangle
   {
    buttonEnabled = false; //Disable button
        
    //This is important, because the libraries are sharing pins
   pinMode(XM, OUTPUT);
   pinMode(YP, OUTPUT);
    
    //Erase the screen
    tft.fillScreen(BLACK);
    
    //Draw frame
    tft.drawRect(0,0,319,240,WHITE);
    
    tft.setCursor(50,50);
    tft.setTextColor(WHITE);
    tft.setTextSize(3);
    tft.print("Thank you fornn   subscribing!");
   }
   delay(10);  
  }
}

Adafruit_HX8357 library compile error (Teensy3.1)

I’ve purchased a 3.5″ TFT 320×480 + Touchscreen Breakout Board w/MicroSD Socket — HXD8357D
PRODUCT ID: 2050 and I’m trying to compile the graphicstest example in Adafruit_HX8357examplesgraphicstest.
for a Teensy3.1.

I’m using arduino 1.6.5 and Teensyduino 1.24

There seems to be no definition of «RwReg» in the include file Adafruit_HX8357.h, as shown by the error message shown below—

In file included from HX8357graphicstest.ino:19:0:
C:UsersDavidDocumentsArduinolibrariesAdafruit_HX8357/Adafruit_HX8357.h:167:14: error: ‘RwReg’ does not name a type
volatile RwReg *mosiport, *clkport, *dcport, *rsport, *csport;

Where is RwReg supposed to be defined, and what type should it be?

The graphicstest program begins with
#include <SPI.h>
#include «Adafruit_GFX.h»
#include «Adafruit_HX8357.h»

Thank you…

Thank you. The example compiles and runs—as long as I choose software SPI.
If I try hardware SPI, the call to tft.begin(HX8357D) does not return.
I tried adding a member function to HX8357 class that called SPI.setMOSI(11),
SPI.setMISO(12), and SPI.setSCK(13), to set those pin numbers, and calling that before any
other calls into the HX8357 class, but that made no difference. Is there a better way?

Previously I successfully used hardware SPI with the ILI9341 class and example program
with an Adafruit 2.8″ touch LCD.
I’m hoping I can get hardware mode to work with this LCD.

Here’s an additional puzzle. Using Arduino 1.0.6, I used the library TouchScreen along with the ILI9341 (all running on Teensy3.1) to build a touch-screen GUI. When I try to use TouchScreen in Arduino 1.6.5 (Teensyduino 1.24), I get compiler errors—

Hi Rick,
I was wondering if there has been any update on a teensy touchscreen library?
I have bought 25 of the 3.5 TFT screens (id:2050) and Teensy’s 3.2 to suit off adafruit for a project.
With the teensy the speed on the screen is quite quick in spi mode.
But I need to get the touch working otherwise I’ll need to change TFT screens.

If there is a Port available it would be much appreciated.

Cheers
Rodney

Hi Rick,
Thanks for the library. I did try it.
I’m using Arduino 1.6.6 and the teensyduino 1.26.
I am getting this error message still.
Ideas?

hello all, this is probably too small of a problem compared to what i ve seen above, but i am trying to use the adafruit ssd1306 library so i can drive a small oled and i really don t have the knowledge to make it work

anyone has any pointer to make it work? currently it fails with ‘fatal error: avr/pgmspace.h: No such file or directory’

which makes sense as this is not an avr/arduino. but don t know what to do next

we don’t have «avr/pgmspace.h», but you may try to replace that with «pgmspace.h»

ah, will try, thanks. (you seem omnipresent )

well, that worked, but now i get cannot convert ‘volatile uint32_t {aka volatile unsigned int}’ to ‘PortReg*

i assume that s because the old and new libraries are returning different value types

can you point me to the code so i can take a look how PortReg is declared?

take a look at the .h file

#ifdef __SAM3X8E__
 typedef volatile RwReg PortReg;
 typedef uint32_t PortMask;
#else
  typedef volatile uint8_t PortReg;
  typedef uint8_t PortMask;
#endif

there is an ifdef for ARM and else for AVR

so i could make those volatile uint32_t

which would match with the esp libs

change that to #if defined( __SAM3X8E__ ) || defined( ESP8266 )

thanks again, removing some more stuff managed to make it compile, now to make it work

@igrr I really wish Arduino didn’t require the avr to include progmem.h
#include <avr/progmem.h>. It makes writing compatible libraries a little more annoying.

how about moving progmem.h to avr/progmem.h and adding progmem.h which will include avr/progmem.h as a fallback?

its a work around, a little misleading as this has nothing to do with Avr, but we didn’t create that problem

well i don’t actually see any other workaround…

agreed, are you doing this?

if you need this right now, do it and send the change. if not, i’ll do this a bit later tonight.

the config is moved as the flash size increases

it takes last 4 sectors of flash

so the SDK detects the «magic bytes» from the bootloader?

and switch the addr range

yeah, there’s a global «FlashChip» object which is set up on start

and sdk reads the flash size from there

so no problems here, perfect.

is there a reason why ESP8266WiFiClass::_getScanInfoByIndex is protected?

I prefer it public access it from outside

well the rationale is that scan_info is a struct from SDK, and in general i tried not to expose SDK types to the user

there is a bunch of methods to access fields of scan_info by index

yes then i need to add to new for channel and bssid and in my code i the call 4 function to get all info

BSSID should be there, i just haven’t implemented it

it’s in standard WiFi Shield library, so we need to have it

and you are welcome to add a new method for the channel

you may add something like getScanInfo(int index, String& ssid, String& BSSID, int& channel, …)

which will fill all the values in one go

i mean, BSSID should be there, but it’s not

as you see i have commented it out and forgot to add it back later

now I had in my 164 the Adafruit_SSD1306 and Adafruit_GFX libs

is there a way to install both so that they would work, because I want (do not have to) use the same arduino for developing both

but they are same libs but for differnt devices (so have changes)

these libs have been modified to use some stuff from Sming, which is not present in this distribution

i have asming insalled in c:tools

sming in c:toolssming (used choco)

but how does the IDE know about that?

the original Adafruit_GFX from Adafruit is working on the ESP8266

I have modified the packaging script to bundle the Adafruit ssd1306 lib with the board manager package

will deploy later tonight

gr8 i am looking forward to tha

not tested i have an ILI9341 display + Adafruit_GFX running here

oh wait that was Adafruit_ILI9341

thats exactly my next question

there was a discussion about SSD1306 though…

i have the 2 screens ssd1306 and that screen

@tzapu did you make any progress with Adafruit_ssd1306 lib?

if i can use the ili3941 with just the 4 spi pins that would be good

ILI9341 is working fine with up to 27fps

SPI + the D/C line and CS

how will i be able to get it? I mean i installed via boardmanager

i will update the board manager package later tonight

you will be able to install via board manager

also there is another display which is supported… esp8266/Arduino#271

don’t know if its useful for you though

no i have the ssd1306 and 3941

i want to connect a rotary encoder too (for controlling menu)

I have code that uses interupts, how do i use interrups in esp arduino?

just like you do it on an arduino — with attachInterrupt

so this code should just work?

well, remember not to do any lengthy stuff from the interrupts and you should be good

if it doesn’t, let me know

what are the pins numbers — is it just 4 — gpio4?

be warned that some ESP-12s (or 7s?) have gpio4 and gpio5 swapped

the silkscreen is incorrect on some of them

so if gpio4 doesn’t seem to work, try swapping them around

to be honest very few are actually correct

even the brand spanking new ESP-12E have them wrong

and it’s been out there for some time

interrupts should work as expected

no Interrupt vector there

it does not seem to work tried 12,14 tried 4,5

@igrr esp8266/Arduino#300 new WiFi functions

int encoderPin1 = 5;
int encoderPin2 = 4;

pinMode(encoderPin1, INPUT);
pinMode(encoderPin2, INPUT);

digitalWrite(encoderPin1, HIGH); //turn pullup resistor on
digitalWrite(encoderPin2, HIGH); //turn pullup resistor on

//call updateEncoder() when any high/low changed seen
//on interrupt 0 (pin 2), or interrupt 1 (pin 3)
attachInterrupt(0, updateEncoder, CHANGE);
attachInterrupt(1, updateEncoder, CHANGE);

@alon24 what version of the IDE are you using?

attachInterrupt(encoderPin1, updateEncoder, CHANGE);

so can i use other pins? what is the correct line?

man… you have interrupt on ALL pins BUT pin 16 and analog input

oh, i am sorry, i did not check to see, i just did the copy/paste — my bad — checking

attachInterrupt([pin_number], [function], [type])

so tonight u add this screen, and u said that ssd1306 was talked about before, a few hours ago.

do u know if it is going to be inserted too soon? when?

i have no clue what screen you are talking about at all

you talked to somebody else

its the ili3941 and its done when igrr hast the time to build and upload it

igrr said that there was talk in the gitter about ssd1306

so i asked if anyone knows what the talk was since, the search does not show me that conversation, because I was not a memener

if someone can do a search on the right they will know

you have the spi or the i2c version?

why not use the Adafruit’s library?

@Links2004 in my latest push gzipped content streaming as well

well you need to comment a few lines

as far as I remember they have TWI = 0; and then restore

@ficeto — do you mean u r adding the lib soon?

a few times in the core functions

@ficeto it is yours, its a merge

no did not say such thing

i do not think addition is needed

so which lines to comment out?

a small edit on the original one and you can make it work

link me to the library source so i dont need to search for it

@ficeto u mean the adafruit — jas

line 27 from #ifdef SAM3X8E

#if defined(__SAM3X8E__) || defined(ESP8266)

that should compile the driver

@Links2004 isn’t the GFX lib alredy in?

works in original version

btw did you notice the new tool in the menu and the debug screen of the Arduino IDE on my screenshot

so here is my question, if i do this, and i use my ise for both arduino nano and esp dev, it will break the arduino nano use of ssd1306 — right?

you want to have twomasters at the same time?

if you want to ensure thefastest speed instead of commenting you can do the following

@ficeto yes looking really good, at he weekend i start the implementation for the webSocket server and after the Client.
i today get me 4MB SPI flash, so webserver incomming

can the webserver handle more the one connection at the same time?

#if !defined(__SAM3X8E__) && !defined(ESP8266)

actually I think I’ll take on SSL first

@ficeto ok so the websocket server will use its own port for the beginning.

actually while working on a large request it’s easy to brick the esp

and async webserver second

i tested a telnet server with web server together and got it working

here is the telnet to serial part

#include <ESP8266WiFi.h>

#define MAX_SRV_CLIENTS 1
const char* ssid = "nbis-test";
const char* password = "1234567890";

WiFiServer server(21);
WiFiClient serverClients[MAX_SRV_CLIENTS];

void setup() {
  Serial1.begin(115200);
  //Serial1.setDebugOutput(true);
  WiFi.begin(ssid, password);
  Serial1.print("nConnecting to "); Serial1.println(ssid);
  uint8_t i = 0;
  while (WiFi.status() != WL_CONNECTED && i++ < 20) delay(500);
  if(i == 21){
    Serial1.print("Could not connect to"); Serial1.println(ssid);
    while(1) delay(500);
  }
  Serial.begin(115200);
  server.begin();
  server.setNoDelay(true);
  Serial1.print("Ready! Use 'telnet ");
  Serial1.print(WiFi.localIP());
  Serial1.println(" 21' to connect");
}

void loop() {
  uint8_t i;
  if (server.hasClient()){
    for(i = 0; i < MAX_SRV_CLIENTS; i++){
      if (!serverClients[i] || !serverClients[i].connected()){
        if(serverClients[i]) serverClients[i].stop();
        serverClients[i] = server.available();
        continue;
      }
    }
    //no free spot
    WiFiClient serverClient = server.available();
    serverClient.stop();
  }
  for(i = 0; i < MAX_SRV_CLIENTS; i++){
    if (serverClients[i] && serverClients[i].connected()){
      if(serverClients[i].available()){
        while(serverClients[i].available()) Serial.write(serverClients[i].read());
      }
    }
  }
  if(Serial.available()){
    size_t len = Serial.available();
    uint8_t sbuf[len];
    Serial.readBytes(sbuf, len);
    for(i = 0; i < MAX_SRV_CLIENTS; i++){
      if (serverClients[i] && serverClients[i].connected()){
        serverClients[i].write(sbuf, len);
        delay(1);
      }
    }
  }
}

tested with up to 4 clients

that’s not bad given that we have 5 TCP connections max

was lazy to poen more screens

then removed http and tested how well will the telnet work

why only 5 connections lwip can normally handle more, limit from espressif?

and with this code i got lots through

yes that’s a limit due to static memory allocation for the TCP stack

we can get over it by building lwIP from source

but I doubt we really need this

k, i have uIP running on a mega board with more the 5 connections

different story because different hardware

can i look at that code btw?

what ethernet controller are you using with it?

.h file

if defined(SAM3X8E) || defined(ESP8266)

typedef volatile RwReg PortReg;
typedef uint32_t PortMask;

else

typedef volatile uint8_t PortReg;
typedef uint8_t PortMask;

endif

.cpp file
// save I2C bitrate

if !defined(SAM3X8E) && !defined(ESP8266)//#ifndef SAM3X8E

uint8_t twbrbackup = TWBR;
TWBR = 12; // upgrade to 400KHz!

endif

if !defined(SAM3X8E) && !defined(ESP8266)//#ifndef SAM3X8E

TWBR = twbrbackup;

endif

@ficeto are those the changes need for the ssd1306?

after the commas shift+enter

now. cant i use wire.pins or something to change i2c pins? for sda scl?

use: wire.begin(sda, scl);
wire.pins are deprecated

the idea is that if you just need to change the pins so that the library which uses Wire.begin() will work, it’s okay

if you are writing a sketch, use Wire.begin(sda, scl)

perhaps need to remove that deprecation warning so not to scare people

or add some #warning there

the problem is in the Adafruit_SSD1306.cpp

#include "pgmspace.h"

ok for removing the warnings simply

#ifndef pgm_read_byte

and

wow espressif did crazy stuff

butt still is 5.

I already added the

 #define pgm_read_byte(addr) (*(const unsigned char *)(addr))
#endif

#ifndef PROGMEM
 #define PROGMEM
#endif

to the cpp, maybe uit should be in the h file

i am going to bed, i give up for today — thanks for the help

hey, if anyone can just do the changes for sdd1306 and post them somewhere, that would be gr8. if not tomorrow is a new day. I will try again.
