In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

I have good experiences with UTFT libraries and its more fast derivatives (olso I maked some modification) on a parallel 16bit display project, now I would like to develop a new project but I have never used SPI displays so I didn"t know if they were better or worse (in terms of speed).

I"m about to have a Display designed on my specifications, with specific characteristics for my needs, so I can choose the type of display, driver and way of use.

It will be a 3.5 320x480 IPS Display, which Driver do you recommend to use? maybe it supports both protocols that I can choose at will, with fuses on PCB, Parallel and SPI?

Arduinos are popular microcontroller boards and a common desired functionality is to use them to drive LCD screens, usually to relay information to the user. In this tutorial, I will teach you how to use the Adafruit I2C/SPI LCD Backpack with an Arduino microcontroller board to drive a LCD.

LCDs require many connections to a driver to work. Managing all these connections all the time can become both cumbersome and annoying. Luckily, Adafruit has made an I2C/SPI LCD Backpack that works with most LCDs. This backpack conveniently reduces the number of connections between your microcontroller and the LCD to 4.

I always like to make a wiring diagram (Figure 1: Arduino-LCD Schematic) using Fritzing, an open-sources schematic capture and PCB routing software. You can download Fritzing using the following link (optional): http://fritzing.org/home/

Pin 1 on the LCD goes to Pin 1 on the LCD Backpack. The rest of the pins are wired sequentially. This can be done on a breadboard or the backpack can be soldered to LCD as I have done.

I2C and SPI are two very popular serial interface buses. This tutorial covers interfacing your Arduino to the LCD Backpack using I2C, but the LCD Backpack can interface with SPI too. You can set the I2C address (A0, A1, A2) or enable SPI (SPI Enable) by jumpering the solder jumpers on the backpack (Figure 2: Solder Jumpers on LCD Backpack). The only circuit using I2C in the tutorial is the LCD Backpack, so we do not need to change the current configurations. This means the LCD Backpack will have an I2C address of 0 (0x00).

To interface the LCD Backpack to the Arduino, connect 5V and a ground pin on the Arduino to the 5V and ground pin on the LCD Backpack. This will provide the LCD and LCD Backpack with power. Note: The LCD requires 5V minimum to work properly. The next two connections are serial data and serial clock. The serial clock connection (orange wire) is between the SCL pin on the Arduino and the CLK pin on the backpack. The serial data connection (blue wire) is between the SDA pin on the Arduino and the DAT pin on the backpack.

The first part of the code is to include the Adafruit_LiquidCrystal header file. This allows you to use the functions in this library. Because the Adafruit_LiquidCrystal library is automatically downloaded with Arduino IDE, this tutorial doesn’t cover downloading Arduino libraries.

Before writing to the LCD, it needs to be initialized. The “begin” function does this by telling the LCD Backpack how many characters are on the display. Since the LCD I am using has a backlight, I also turn the backlight on.

Now that the LCD is initialized, I write “Test Code” to check that everything is working. This code sets the cursor to a starting position, writes “Test” to the display, waits 2 seconds, and then clears the display.

The loop part of the code uses the millis() function and divides by 1000 to compute how long the program has been running. The code then uses the print and setCursor functions to display the program time across the LCD. The loop then waits a second before repeating.

Upload the code to the Arduino. Make sure the Arduino is connected using the 9V Power Adapter because power over USB is not sufficient to power both the Arduino and the LCD display. Once the program begins you should see “Test” across the LCD display as the program runs through setup (Figure 2: LCD Displaying “Test”). When the program loop begins you will see the time program displayed and updating every second (Figure 3: LCD Display Program Runtime – 8(s)). Congrats! You now have an easy-to-use LCD screen for your Arduino board and can use it as a display for future projects. A tip to keep in mind: I2C is a slow bus and if you are constantly updating your LCD you will take time away from the controller performing other tasks.

Your customers can choose the aruino lcd display for a variety of purposes, such as creating a variety of learning materials. Having an options of display aruino lcd displays in bulk, it is easy to use and consume less. Your customer can choose the aruino lcd display depending on their needs and preferences. Lcd display or aruino lcd display depending on the needs of the user.

Your customers can use different aruino lcd displays to provide information such as watching videos, gamers, and hobbyists. An aruino lcd display provide user-friendly design for the activities to watch and watch TV shows, or for a games-designer look for an aruino display that is useful to watch at least one of the basic functions of using TV.

Unlike an aruino lcd display, the lcd display have many functions and interfaces that allow it to be adjusted based on a game of thumb. On Alibaba.com, you can find aruino lcd displays in bulk and are the most popular lcdds at wholesale prices.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println();. First add Serial.begin(9600); in setup().

Arduino is an open-source electronics prototyping platform based on flexible & easy-to-use HW and SW. It"s intended for creating interactive objects or environments (it can read sensors, perform actions based on inputs from buttons, control motors, etc...).

All Arduino boards have one thing in common: they are programmed through the Arduino IDE. This is the software that allows you to write and upload code.

TFT Displays provide rich colors, detailed images, and bright graphics with their full-color RGB mode. TFT displays are perfect for applications including industrial instruments, coffee machines, automation, GPS navigator, energy control, and medical devices.
