nodemcu esp8266 1.8 tft lcd price

I am using the 1.8″ color ST7735 TFT display a lot. The reason for that is that this display is very easy to use, it costs less than $5 and it offers color! At the back, the display has an SD card slot.A brief summary of the pins (adapted from Adafruits thorough summary):

RST – this is the TFT reset pin. Connect to ground to reset the TFT! Its best to have this pin controlled by the library so the display is reset cleanly, but you can also connect it to the Arduino Reset pin, which works for most cases.CS – this is the TFT SPI chip select pinD / C – this is the TFT SPI data or command selector pinDIN – this is the SPI Master Out Slave In pin (MOSI), it is used to send data from the microcontroller to the SD card and / or TFTSCLK – this is the SPI clock input pinVcc – this is the power pin, connect to 5VDC – it has reverse polarity protection but try to wire it right!LED – this is the input for the backlight control. Connect to 5VDC to turn on the backlight.GND – this is the power and signal ground pinNow that we know what we’re dealing with it’s time to start wiring!

Pins D5 (GPIO14) and D7 (GPIO13) are hardware SPI module pins of the ESP8266EX microcontroller respectively for SCK (serial clock) and MOSI (master-out slave-in).

The first library is a driver for the ST7735 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7735” and install the one from Adafruit).

Project hardware circuit should give the same result as the one shown in the following video where Arduino UNO board is used (NodeMCU is much faster than Arduino UNO):

For an upcoming new project I wanted a colour (UK spelling) LCD screen (ideally OLED), 256×256 (or greater) resolution and nice and cheap. It was not an easy 2 minute task. There were no OLED screens offering what I wanted (that I could see at the time). So compromises were made, in the end I purchased a 128×128 pixel screen (none OLED) for around $3.50 (£3.20, 3.50 Euro). Not as cheap as I thought I might get one for but the cheapest I could find. There were a lot of sellers offering this screen and it’s shown below.

Due to the planned game being more advanced than Space Invaders I needed a processor with more memory and speed than the Arduino could offer. Enter the ESP8266 processors which offer faster speeds and lots and lots more memory. Wifi is also available but will not be required for this project unless we implemented a World High Score Table perhaps! There are newer versions, ESP32, available with even more power but are more expensive and we don’t need that level of performance for this project. I’m using a NodeMCU from Lolin, which is basically a breakout board for the ESP8266 so that you can use it easily on breadboards or small production runs using through hole.

Power is self explanatory. LED adds a little extra brightness to the screen but it does still work if not connected. I’ve seen resistors added in series here and even variable ones to vary the brightness but I’ve ran it directly connected on this screen with no issues and wouldn’t want it dimmer as its not ultra bright. It is actually on even when not connected giving adequate brightness in my opinion. SCL is the SPI clock and goes to the NodeMCU’s hardware SPI pin (pin D5). SDA is actually the SPI MOSI connection and goes to the NodeMCU’s SPI MOSI pin (D7). RS is a Regsiter Select pin for ST7735 driver chips, this maps to a variable called TFT_DC in the Adafruitcode (explained later) that I was using for testing. This controls whether we are sending a command to the ST7735 chip or actual data. I think that Adafruit call it DC meaning Data Control, but I’m not sure. On some boards it may even be referred to as A0. For our purposed we connect it to D4. RST is the screen reset and and is connected to pin D3. These last two can connect to any NodeMCU pins that are not used for other functions. CS is Chip Select (usually referred to as Slave Select in the SPI protocol) and again can connect to any pin but I use D2. If this is pulled low then this device can receive or send data on the SPI bus. If only one device in your design you could pull this low permanently and not use D2.

Load up the example code that should now be available at “Files->Examples->XTronical ST7735 Library->GraphicsTestESP8266”. This is basically the Adafruit example with just some tiny changes (It goes through all the tests for each rotational position of the screen) so that it uses the new driver file and slightly altered initialisation routine.

There is an issue with the line drawing routine within the Adafruit GFX library, so this part of the original demo was removed. Basically it forces the NodeMCU to reset. As I’m not going ot be using this I’ve decided for now to ignore this issue.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

The capability to read from an ST7789V TFT with a single bidirectional SDA pin has been added. At the moment this ONLY works with an ESP32. It is enabled with a #define TFT_SDA_READ in the setup file.

An Arduino IDE compatible graphics and fonts library for ESP8266 and ESP32 processors with drivers for ILI9341, ILI9163, ST7735, S6D02A1, ILI9481, ILI9486, ILI9488, HX8357D and ST7789 based TFT displays that support SPI. The library can be loaded using the Arduino IDE"s Library Manager.

The library supports TFT displays designed for the Raspberry Pi that are based on a ILI9486 driver chip with a 480 x 320 pixel screen. This display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. A modification to these displays is possible (see mod image in Tools folder) to make many graphics functions much faster (e.g. 23ms to clear the screen, 1.2ms to draw a 72 pixel high numeral).

Some displays permit the internal TFT screen RAM to be read. The library supports reading from ILI9341, ST7789 and ILI9488 SPI displays for the ESP32 and ESP8266. The 8 bit parallel displays used with the ESP32 can usually can be read too. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.

The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.

A Sprite is notionally an invisible graphics screen that is kept in the processors RAM. Graphics can be drawn into the Sprite just as they can be drawn directly to the screen. Once the Sprite is completed it can be plotted onto the screen in any position. If there is sufficient RAM then the Sprite can be the same size as the screen and used as a frame buffer. Sprites by default use 16 bit colours, the bit depth can be set to 8 bits (256 colours) , or 1 bit (any 2 colours) to reduce the RAM needed. On an ESP8266 the largest 16 bit colour Sprite that can be created is about 160x128 pixels, this consumes 40Kbytes of RAM. On an ESP32 the workspace RAM is more limited than the datsheet implies so a 16 bit colour Sprite is limited to about 200x200 pixels (~80Kbytes), an 8 bit sprite to 320x240 pixels (~76kbytes). A 1 bit per pixel Sprite requires only 9600 bytes for a full 320 x 240 screen buffer, this is ideal for supporting use with 2 colour bitmap fonts.

Drawing graphics into a sprite is very fast, for those familiar with the Adafruit "graphicstest" example, this whole test completes in 18ms in a 160x128 sprite. Examples of sprite use can be found in the "examples/Sprite" folder.

The XPT2046 touch screen controller is supported. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed.

The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses.

The library is based on the Adafruit GFX and Adafruit driver libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for ESP8266/ESP32 processors (it is typically 3 to 10 times faster) and to add new features. The new graphics functions include different size proportional fonts and formatting features. There are lots of example sketches to demonstrate the different features and included functions.

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editting the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.

Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linked in the 3 spare pins IO15, IO33 and IO32 by adding wires to the bottom of the board as follows:

The library was intended to support only TFT displays but using a Sprite as a 1 bit per pixel screen buffer permits support for the Waveshare 2 and 3 colour SPI ePaper displays. This addition to the library is experimental and only one example is provided. Further examples will be added.

The ESP8266 is a well performing microcontroller chip that is fully Arduino compatible. Its WiFi capability makes boards with this chip easy implementable as IOT devices. Here we wire two representative ESP8266 boards: NodeMCU and Wemos D1 mini to a single-row 14-pin header, 320*240 TFT display that uses the four-wire SPI interface.

Here we connect a 320240 ILI9341 TFT display that has a SPI pin-out. This breakout board has 3.3V controller logic while power supply and background illumination operate on either 3.3V and 5V. ESP8266 microcontroller boards support displays with up to 320480 pixels

The display shown in figure 1 has a touch screen. It has a single row of 14 pins (figure 1; see also figure 3). The pins supporting ‘touch’ as well as those associated with the SD card reader are not connected: we concentrate on displaying text, variables, graphics and fast sequences of memory-loaded bitmaps (‘image frames”). The ILI9341 controller is fast and, in combination with an ESP8266, performs excellently.

Figure 3 shows a Wemos D1 mini board mounted on a prototyping breadboard together with a 2.8 inch ILI9341 SPI TFT display according to the wiring diagram shown in Figure 2. The ESP8266 is running a demo adapted for the “Adafruit_GFX.h” and “Adafruit_ILI9341.h” libraries from Bodmer’s ‘Clock’ example for his TFT_eSPI library.

The reason I posted was because the project is now at the stage where the LCD display really needs to be added and I intended to get advice before making another purchase. In the meantime I have been working on the project using a 20x4 display.

Thank you for that information. Since I am using an ESP8266, it sounds like I need to look for a board that uses SPI for the display. From what I can tell, it seems that some of the cheap ones from china only use SPI only for the SD card which further confuses things.

The LT7381 board referenced earlier was meant to work over SPI and that is how I tried to use it. I will make sure that whatever I get as its replacement can also be driven via SPI. I expect that the ESP8266 has insufficient pins for parallel?
