A number of display devices like LEDs, 7-segments, character and graphic displays can be attached to microcontrollers to create an interface between the user and an electronic system for displaying data or controlling the system. Sometimes you may need to add colorful images or graphics to your project, that’s where the TFT color displays come in handy.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. In this tutorial we are going to show how to interface a 1.44″ TFT color display based on the ST7735 driver. It has 128×128 color pixels and can display full 16-bit color.

This is the type of display am using but they come with various pin configurations. However all the displays will have the major pins stated below and should be connected to the Arduino board as follows:

This TFT display uses 3.3V but comes with an on board voltage regulator therefore the VCC can be connected to the Arduino 5V. However for best practice it’s better to use the 3.3V.

Most code Libraries for this TFT ST7735 display with Arduino are programmed with the SDA and SCL pins connected to Arduino pins 11 and 13 respectively. Make sure you don’t change that order otherwise the display may not work.

There are a number of libraries that have been developed to run the TFT ST7735 color display using Arduino but I found the Adafruit-ST7735-Librarythe best to use. Make sure you have this library installed in your IDE.

tft.fillRoundRect(x,y,w,h,r,t); function draws a filled Rectangle with r radius round corners in x and y location and w width and h height and t color.

There are many other functions and commands which you can use to program the TFT color display but the above are the commonest. You will meet many more with practice.

Before we can write our personal code we need to first test the display using the already made code examples from the installed library. This is done by going to File>Examples>Adafruit ST7735 and ST7789 Library. Then you can select any of the examples and upload it to the setup to see if the display works fine.In the diagram below I have shown how to access the graphics test code.

Este pequeño display LCD de 1.8 pulgadas SPI ST7735 es ideal para pequeños proyectos electrónicos como reproductores y grabadores de sonido, robots y dispositivos IoT. Gracias a su interfaz SPI y el controlador ST7735 se puede manejar mediante una amplia variedad de microcontroladores como Arduino, Raspberry Pi, PIC, etc.

En la parte de software el display es compatible con las librerías GFX de Adafruit, por lo que podemos comenzar a desarrollar con el de forma sumamente sencilla. Otra característica es que el controlador cuenta con un buffer interno que facilita utilizar esta pantalla con microcontroladores que tienen poca memoria RAM y pocos pines (solamente requiere de 4 pines de la interfaz SPI).

Con una resolución de128 x 160 pixeles y dimensiones de 31 X 38 mm este display posee una excelente densidad de pixeles y será ideal para agregar una interfaz de usuario colorida y vistosa en cualquier proyecto.
