1.8 st7735r spi tft lcd display module made in china

The 1.8inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)

ST7735S is a 132*162 pixel LCD, and this product is a 128*160 pixel LCD, so some processing has been done on the display: the display starts from the second pixel in the horizontal direction, and the first pixel in the vertical direction. Start to display, so as to ensure that the position corresponding to the RAM in the LCD is consistent with the actual position when displayed.

The LCD supports 12-bit, 16-bit and 18-bit input color formats per pixel, namely RGB444, RGB565, RGB666 three color formats, this routine uses RGB565 color format, which is also a commonly used RGB format

Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirement.

Framebuffer uses a video output device to drive a video display device from a memory buffer containing complete frame data. Simply put, a memory area is used to store the display content, and the display content can be changed by changing the data in the memory.

If you need to draw pictures, or display Chinese and English characters, we provide some basic functions here about some graphics processing in the directory RaspberryPi\c\lib\GUI\GUI_Paint.c(.h).

Set points of the display position and color in the buffer: here is the core GUI function, processing points display position and color in the buffer.

The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen.

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.;

2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself

Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.

Note: Each character library contains different characters; If some characters cannot be displayed, it is recommended that you can refer to the encoding set ro used.

The first parameter is a tuple of 2 elements, with (40, 50) as the left vertex, the font is Font2, and the fill is the font color. You can directly make fill = "WHITE", because the regular color value is already defined Well, of course, you can also use fill = (128,255,128), the parentheses correspond to the values of the three RGB colors so that you can precisely control the color you want. The second sentence shows Micro Snow Electronics, using Font3, the font color is white.

The demo is developed based on the HAL library. Download the demo, find the STM32 program file directory, and open the LCD_demo.uvprojx in the STM32\STM32F103RBT6\MDK-ARM directory to check the program.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory STM32\STM32F103RB\User\GUI_DEV\GUI_Paint.c(.h)

Image buffer part of the window filling color: the image buffer part of the window filled with a certain color, generally as a window whitewashing function, often used for time display, whitewashing on a second

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

DEV_Config.cpp(.h): It is the hardware interface definition, which encapsulates the read and write pin levels, SPI transmission data, and pin initialization;

image.cpp(.h): is the image data, which can convert any BMP image into a 16-bit true color image array through Img2Lcd (downloadable in the development data).

The hardware interface is defined in the two files DEV_Config.cpp(.h), and functions such as read and write pin level, delay, and SPI transmission are encapsulated.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory GUI_Paint.c(.h)

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

The document section provided support for the module with 11 pins. But the one that you supplied has 8 pins only. How am I supposed to work with this?

As you suggested, in addition to wiring up the display via the "yellow" connectors, I have wired up the pins on the opposite side of the board to the Arduino... it"s a standalone Arduino on a breadboard that runs at 16 MHz external, if it matters... anyway, here"s my pinout:

I had an application where I needed the LCD display to be separate from the Arduino (Wemos D1). This let me run a ribbon cable from the panel to behind where the arduino was mounted.

The ST7735 color TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display an extensive range of colors. It utilizes the SPI protocol for communication, features its own pixel-addressable frame buffer, and only needs four I/O pins of a microcontroller. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

The hardware setup for this experiment is fairly easy as the only thing you need to wire with the Arduino Uno is the TFT display. Well, connect the TFT display module to the Arduino Uno as pointed in the table below.

The ST7735 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD, which consists of 396 source line and 162 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor and accepts Serial Peripheral Interface (SPI), 8-bit/9-bit/16-bit/18-bit parallel interface. Display data can be stored in the on-chip display data RAM of 132 x 162 x 18 bits.

The ST7735 can perform display data RAM read/write operation with no external operation clock to minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to make a display system with fewer components

Also read this loosely related guide http://www.lcdwiki.com/1.8inch_Arduino_SPI_Module_ST7735S_SKU:MAR1801 Now, you can see below a seller’s description of the TFT display used in my experiments.

It’s very crucial to note at this point that the maximum power supply voltage for the ST7735 display driver chip is 3.3V and same for its interface pins. Some TFT modules include a 3.3V regulator and a logic level shifter onboard in which case it can be used with any 5V microcontrollers. If not, some logic level shifting must be done if the microcontroller is not powered from 3.3V!

Copy the following code to your Arduino IDE and upload it to your Arduino Uno. This code displays “HELLO MAKER!” in the middle of the screen and changes the font color every 500 milliseconds.

Note that since the TFT display communicates with the Arduino via SPI communication, you need to include the SPI library in your code. You also need to use the TFT library, which’s already included with Arduino IDE 1.0.5, and later, to write and draw on the TFT display.

Below is another easiest example code to manifest the possibilities of the TFT display. This no-frills Arduino Sketch simply displays the value of Uno’s analog input A0 on the TFT display.

And sure enough, the TFT library enables the Arduino to communicate with the TFT display module, and it simplifies the process of drawing lines, shapes, images, and text to the display screen. Note that the TFT library relies on the SPI library for communication with the display and SD card, and needs to be included in all sketches. For additional information, see this page https://www.arduino.cc/reference/en/libraries/tft/.

In my book, this ST7735 display controller based 1.8″ colour TFT display is a very handy module for use in microcontroller projects. Here I just discussed about displaying elements on the TFT display but you can follow my upcoming tutorials to learn more about making a bit more advanced display projects.
