raspberry pi 1.8 tft display 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.)

The example we provide is based on STM32F103RBT6, and the connection method provided is also the corresponding pin of STM32F103RBT6. If you need to transplant the program, please connect according to the actual pin.

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.

2.We use Dev libraries by default. If you need to change to BCM2835 or WiringPi libraries ,please open RaspberryPi\c\Makefile and modify lines 13-15 as follows:

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.;

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.

Open main.c, you can see all the test programs, remove the comments in front of the test programs on the corresponding screen, and recompile and download.

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;

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.

Please take care of the direction when you connect Pico, an USB port is printed to indicate. You can also check the pin of Pico and the LCD board when connecting.

Open main.c under the c folder, you can change the routine you need. This routine can drive the display of our company"s Pico series and the source code will be updated all the time. Please select the corresponding LCD or OLED test function and comment out the irrelevant functions.

After the compilation is complete, the uf2 file will be generated. Press and hold the button on the Pico board, connect the pico to the USB port of the Raspberry Pi through the Micro USB cable, and release the button.

TFT display module is a Thin Film Transistor, and AMOLED is Active-matrix organic light-emitting Display. The TFT display module is backlight-on the liquid crystal panel; AMOLED is a panel that emits light on its own; TFT display module structure is more thick and strong, AMOLED is very thin and also weak, TFT display module is used widely than AMOLED, AMOLED is used in consumer products the most, like a smartwatch, mobile phone, and TV.

IPS is In-Plane Switching, It is also known as free viewing angle, which means the viewing angle of the display on 4 sides is the same, a normal display has its best viewing angle like 6 o’clock or 12 o’clock. While the TFT display module contains normal viewing angles and IPS display,IPS display is a kind of TFT display module.

TFT display module belongs to LCD, LCD is Liquid Crystal Display, it contains mono(single color) LCD and color LCD, single color LCD is barely used now, and color LCD has STN and TFT two types. Therefore, TFT display module is a kind of LCD display.

OLED is Organic Light Emitting Display, it is a display that emits light on its own, and it does not need an extra backlight, so it requests lower power consumption than TFT display module but its lifetime is shorter than TFT(5000 hours), AMOLED is a kind of OLED but it is more colorful. TFT display module requests a backlight to light on and power consumption are higher than OLED, but its lifetime is much longer(20000 hours).

The LED display is working by lighting up the LED lights, the TFT display module is lighted up by the backlight and the liquid crystal starts to work and shows contents. TFT display module has brighter and more true color, and lower price and LED display has lower power consumption, smaller heat, and longer lifetime.

Compares to other types of display, TFT display module is the more widely used, it can be made in different shapes and sizes, from very small sizes to big sizes. The resolution now is higher and higher, and the price of custom TFT display modules is more and more competitive. Its lifetime is longer than the OLED display, and its color is brighter than OLED.

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows to easily read full-color bitmaps from the SD card. The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly use an FPC cable to connect the display to any controller with GDI interface like FireBeetle-M0. Plug and play, easy to wire. Besides, the display supports low refresh rate and offers good display effect and strong versatility. It can be used in applications like sensor monitoring and alarm, Arduino temperature monitor, fan controller, etc.

This product is a breakout module that features SPI communication mode and onboard GDI interface, which could reduce the complexity of wiring. It can easily display the read content from the SD card.
