The content is intended to be updated from time to time, I will add more details if I found new display or library update. You can also help me enrich the content by leaving comments below.

You can run various IoT projects prefectly without any display. But not all IoT project only feed data in single direction (IoT to server), some IoT also gather real time information from the server for displaying.

My previous instructables, ESP32 Photo Clock is am example, it download a current minute photo from the Internet, decode the JPEG photo and display it.

Many Arduino projects use monochrome display, one of the reason is the limited resources of a MCU. 320 pixels width, 240 pixels height and 8 bits color for each RGB color channel means 230 KB for each full screen picture. But normal Arduino (ATmega328) only have 32 KB flash and it is time consuming (over a second) to read data from SD card and draw it to the color display.

ESP32 have changed the game! It have much faster processing power (16 MHz vs 240 MHz dual core), much more RAM (2 KB vs over 200 KB) and much more flash (32 KB vs 4 MB), so it is capable to utilize more color and higher resolution image for displaying. At the same time it is capable to do some RAM hungry process such as Animated GIF, JPEG or PNG file decoding, it is a very important feature for displaying information gathered from the internet.

Color display have many type of interfaces: Serial Peripheral Interface (SPI), 6-bit, 8-bit, 16-bit, 18-bit and 24-bit parallel interfaces and also NeoPixel!

SPI dominate the hobby electronics market, most likely because of fewer wire required to connect. Most display in my drawer only have SPI pins breaking out, so this instructables focus on SPI display and a few 8-bit display.

NeoPixel matrix is a very special type of color display. If you are interested in NeoPixel matrix display, here are some of my instructables using it:

There are various color display for hobby electronics: LCD, IPS LCD, OLED with different resolutions and different driver chips. LCD can have higher image density but OLED have better viewable angle, IPS LCD can have both. OLED have more power efficient for each light up pixel but may have burn-in problems. Color OLED operate in 14 V, it means you need a dedicate step-up circuit, but it is not a problem if you simply use with a break-out board. LCD in most case can direct operate in 3.3 V, the same operating voltage as ESP32, so you can consider not use break out board to make a slimmer product.

Software support on the other side also influence your selection. You can develop ESP32 program with Arduino IDE or direct use ESP-IDF. But since ESP-IDF did not have too much display library and not much display hardware supported, so I will concentrate on Arduino display libraries only.

OLED have a big advantage, the pixel only draw power if it lights up. On the other hand, LCD back light always draw full power even you are displaying a black screen. So OLED can help save some power for the project powered by a battery.

This is a 1.5" 128 x 128 color OLED, this form factor is very fit for smart-watch-like wearable project. The most barrier of select this should be the price tag is around 4 times of a normal LCD.

ST7735 is a very popular LCD driver model for the resolution 128x128 and 128x160. It may cause by its popularity, there are many manufacturer produce compatible product. However, they are not fully compatible.

Thanks for the popularity of wearable gadget, I can find more small size IPS LCD in the market this year(2018). The above picture is an 0.96" 80x160 IPS color LCD using ST7735 driver chip. As you can see in the 3rd picture, you can treat it as a 128x160 color display in code but only the middle part is actually displaying. The 4th picture is the display without breakout board, it is thin, tiny and very fit for a wearable project!

SSD1283A is 1.6" 130x130 display, it claim only consume 0.1 in sleep mode and backlight turned off. In sleep mode the last drawn screen still readable under sufficient lighting.

It is a 2.2" 176x220 color LCD. It is relatively fewer projects using this chips and resolution. It may caused by the success of its chip family brother, ILI9341 (0.2" larger in size but have near double resolution).

I think ILI9341 is the most popular LCD driver chip in the hobby electronics market. In most case it is 240x320 resolution and have many screen size from 1.7" to 3.5". Some breakout board also built-in touch screen feature.

ST7789 also a common driver chip in ESP32 community. One of the reason is ESP32 official development kit using it. As same as ILI9341, ST7789 also can drive 240x320 resolution.

This also the highest pixel density color display in my drawer. As same as normal LCD, it can direct operate in 3.3 V, so it is very good for making slim wearable device.

There are many display libraries that can support various hardware. I have picked 4 of most popular Arduino library for comparison:Adafruit GFX Family

The display speed is one of the most important thing we consider to select which library. I have chosen TFT_eSPI PDQ test for this comparison. I have made some effort to rewrite the PDQ test that can run in 4 libraries. All test will run with the same 2.8" ILI9341 LCD.

As I found TFT_eSPI is the most potential display library for ESP32 in this instructables, I have paid some effort to add support for all my display in hand. The newly added display support marked letter M in red at the above picture, here is my enhanced version:

Adafruit sell various display module in hobby electronics market and they also have very good support in software level. Their display libraries all built on a parent class called Adafruit_GFX, so I call it Adafruit GFX Family. This library generally support most Arduino hardware (also ESP32).

In Arduino Library Manager simply search "adafruit display", you can see all the family members. If you want to install it, say ILI9341, simply select "Adafruit ILI9341" and then click install. Remember also install its dependent library "Adafruit GFX Library".

This library method signature is very similar to Adafruit GFX, but it is tailor-made for ESP8266 or ESP32. I think the source code is optimised for ESP32, so the PDQ result is much faster than other libraries.

#define LOAD_GLCD // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2 // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters

ESP32 + ILI9341 can run at SPI speed 40 MHz, it require some code change at library folder. The above pictures are the fine tuned result. Here are the code change summary:

ST7735 and ILI9341 are the most popular display, this 2 are better option for the beginner. You may notice LCD have a big weakness, the viewable angle, some color lost outside the viewable angle and the screen become unreadable. If you have enough budget, OLED or IPS LCD have much better viewable angle.

ILI9341 should be most valuable display for the beginner. Adafruit GFX Library should be most easy to use for the beginner, and since TFT_eSPI have very similar method signature, it is very easy to switch to a faster library later on.

OLED require 14 V to light up the pixel so it is not easy to decouple the breakout board. On the other hand, LCD (also IPS LCD) usually operate in 3.3 V, as same as the ESP32. In most case, there are only the LED control circuit required between LCD and ESP32, i.e. a transistor and few resistors. So it relatively easy to make it.

It is very important to read the data sheet first before you decide not using breakout board. The pins layout, pin pitch size, the sample circuit connection and maximum rating all you can find in data sheet. The maximum voltage is especially important, you should sticky follow the rating or you will blow your LCD. The chip can operate in 3.3 V but LED may be 2.8 - 3.0 V so it require some electronics in the middle, most data sheet have the sample circuit. You may ask your seller send a soft copy of data sheet to you or simply Google it by the model number.

My special hint: I like to soldering a FPC cable with the same pin pitch size as the LCD to help the connection with the MCU. I have used this technique in these instructables:

If you read through the data sheet of the color display, you may find most of color display can support 18 bit color depth (6 bit for each RGB channel). 18 bit color depth can have a better image quality that 16 bit color depth (5 bit in red and blue channel, 6 bit for green channel). However, only Ucglib actually run at 18 bit color depth (262,144 colors), other 3 libraries all run at 16 bit color depth (65,536 colors). It is because 18 bit color depth actually require transfer 3 bytes (24 bit) of data for each pixel, it means 50% more data require to transfer and store in memory. It is one of the reason why Ucglib run slower, but it can have a better image quality.

Thank you very much for posting this detailed review of the color display option available for "Duino users. You have saved me hours, maybe days of time wandering the web looking for information.0

Great article! Very interested in round displays. There are available round displays based on st7687s (128 * 128) and st7789 (240 * 240), but I have not found any information on practical use.

Hello! Yes, I purchased this display from keyestudio, connected it to esp32 using this library from dfrobot. It is only necessary to consider that the pinout of the display connectors differs from dfrobot and keyestudio.

I"m wanting to connect a VGA camera, the sort you find as a little module on eBay with OVPxxxx chip, to a screen such as ILxxxx family, which appears to have direct VGA input. I think it will work if I connect the camera directly with no MCU, but I"d also like to add a cross-hair to the display (for a drill targetting system). I wonder is it possible to intercept the serial video data and change individual pixels in a streaming fashion, instead of loading a whole screen into memory, changing it and passing it on? I ask because it seems to me it would need a much less powerful MCU.0

Thank you so much for such a great article. I have been trying to choose the best library to use for a project that will use either a SSD1351 or a ST7735 both being 128x128. The key to my project is to be able to dump a frame buffer in to the display and then recalculate the next frame buffer. :)

So, basically I make a reset in the beggining (read datasheet) then next I use only SPI_DAT and SPLI_CLK. If I destroy the sequence touching with an oscilloscope, the LCD stops to understand the sequence DAT/CLK and I have to make another reset.

Those 2 pins must be dedicated to the display, otherwise the display will get confused without the CS pin. One DAT/CLK to LCD and another DAT/CLK to I2C.

Hello! Thank"s for your instruction. I want to use your 8pin ili9486 320x480 spi display with one of your presented libraries and esp32. 1.) Could you please tell me the connections between the display and the esp32 and 2.) which numbers do I have to write into the line utft myglcd (ili9486,?,?,?,?)?

A few weeks ago, we examined the features of ESP32 module and built a simple hello world program to get ourselves familiar with the board. Today, we will continue our exploration of the ESP32 on a higher level as we will look at how to interface a 16×2 LCD with it.

Displays provide a fantastic way of providing feedback to users of any project and with the 16×2 LCD being one of the most popular displays among makers, and engineers, its probably the right way to start our exploration. For today’s tutorial, we will use an I2C based 16×2 LCD display because of the easy wiring it requires. It uses only four pins unlike the other versions of the display that requires at least 7 pins connected to the microcontroller board.

ESP32 comes in a module form, just like its predecessor, the ESP-12e, as a breakout board is usually needed to use the module. Thus when it’s going to be used in applications without a custom PCB, it is easier to use one of the development boards based on it. For today’s tutorial, we will use the DOIT ESP32 DevKit V1 which is one of the most popular ESP32 development boards.

The schematics for this project is relatively simple since we are connecting just the LCD to the DOIT Devkit v1. Since we are using I2C for communication, we will connect the pins of the LCD to the I2C pins of the DevKit. Connect the components as shown below.

Due to the power requirements of the LCD, it may not be bright enough when connected to the 3.3v pin of the ESP32. If that is the case, connect the VCC pin of the LCD to the Vin Pin of the ESP32 so it can draw power directly from the connected power source.

At this point, it is important to note that a special setup is required to enable you to use the Arduino IDE to program ESP32 based boards. We covered this in the introduction to ESP32 tutorial published a few weeks go. So, be sure to check it out.

To be able to easily write the code to interact with the I2C LCD display, we will use the I2C LCD library. The Library possesses functions and commands that make addressing the LCD easy. Download the I2C LCD library from the link attached and install on the Arduino IDE by simply extracting it into the Arduino’s library folder.

Before writing the code for the project, it’s important for us to know the I2C address of the LCD as we will be unable to talk to the display without it.

While some of the LCDs come with the address indicated on it or provided by the seller, in cases where this is not available, you can determine the address by using a simple sketch that sniffs the I2C line to detect what devices are connected alongside their address. This sketch is also a good way to test the correctness of your wiring or to determine if the LCD is working properly.

If you keep getting “no devices found”, it might help to take a look at the connections to be sure you didn’t mix things up and you could also go ahead and try 0x27 as the I2C address. This is a common address for most I2C LCD modules from China.

Our task for today’s tutorial is to display both static and scrolling text on the LCD, and to achieve that, we will use the I2C LCD library to reduce the amount of code we need to write. We will write two separate sketches; one to displaystatic textsand the other to display both static and scrolling text.

To start with the sketch for static text display, we start the code by including the library to be used for it, which in this case, is the I2C LCD library.

Next, we create an instance of the I2C LCD library class with the address of the display, the number of columns the display has (16 in this case), and the number of rows (2 in this case) as arguments.

With that done, we proceed to the void setup() function. Here we initialize the display and issue the command to turn the backlight on as it might be off by default depending on the LCD.

Next is the void loop() function. The idea behind the code for the loop is simple, we start by setting the cursor to the column and row of the display where we want the text to start from, and we proceed to display the text using the lcd.print() function. To allow the text to stay on the screen for a while (so its visible) before the loop is reloaded, we delay the code execution for 1000ms.

For the scrolling text, we will use some code developed by Rui Santos of RandomNerdTutorials.com. This code allows the display of static text on the first row and scrolling text on the second row of the display at the same time.

Next, we create an instance of the I2C LCD library class with the address of the display, the number of columns the display has (16 in this case), and the number of rows (2 in this case) as arguments.

Next, we create the function to display scrolling text. The function accepts four arguments; the row on which to display the scrolling text, the text to be displayed, the delay time between the shifting of characters, and the number of columns of the LCD.

Next is the void setup() function. The function stays the same as the one for the static text display as we initialize the display and turn on the backlight.

With that done, we move to the void loop() function. We start by setting the cursor, then we use the print function to display the static text and the scrollText() function is called to display the scrolling text.

Ensure your connections are properly done, connect the DOIT Devkit to your PC and upload either of the two sketches. You should see this display come up with the text as shown in the image below.

That’s it for today’s tutorial guys. Thanks for following this tutorial. This cheap LCD display provides a nice way of providing visual feedback for your project and even though the size of the screen and the quality of the display is limited, with the scrolling function you can increase the amount of text/characters that can be displayed.
