stm32 tft lcd interface in stock

According to the Setup, the LCD_D2 is connected to the PA15. So if I want to write the DATA to the LCD_D2 pin, first I will select the 2nd bit of the data (d & (1<<2)), and than shift this by 13 using <<13. This will be like adding 2 with 13 to make a total of 15, and that’s where the LCD_D2 is connected to.

Similarly, LCD_D7 is connected to PA5. So to write the data, first we will select the 7th bit of the data (d & (1<<7)), and this time shift it RIGHT by 2 (>>2). This is like subtracting 7-2=5. And that’s where, the D7 is connected to.

The process here remains the same. Except, we have to first select the GPIO Pin, and than shift it according to the position of the LCD Pin, that it is connected to. In the function above, we are first selecting the PB0 pin, and as it is connected to LCD_D0, we don’t need to shift it anywhere. Same for the PB1 also.

Next, we are selecting PA15, and as this one is connected to the LCD_D2, we need to shift it by 13 to the right ( >>13). This process continues for all other pins too.

After all the Pins work is done, we still need to select the delays according to our clock frequency. As I am using STM32F103C8 at72 MHz, I am going to uncomment the respective code as shown below.

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)

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.

The board offers additional and independent GPIOs over a 40pin, 1.27mm male header. It provides direct access to the below GPIOs of MCU STM32H757XIH6, that makes it possible to be easily extended by an addon board for specific application.

SWD connector allows to program STM32 and QSPI with customer’s applications. Riverdi developed the ST-LINK programming cable that is included in the STM32 Embedded Display sample package (single packing).

In some applications there might be a need to connect a second display in one device. With the STM32 Embedded Display line it is very easy as these displays are equipped with Master RiBUS connector – universal interface to Riverdi’s intelligent displays. In this way, the second display does nots need an external host controller and 2 independent displays can be controlled by one STM32.

The board is equipped with a separate 512Mb flash memory. It can store pictures, music, video, fonts, etc. QSPI can be accessed over the SWD interface on the board with any official ST programmer.

Power supply voltage ranges from 6.0 V- 36.0V. A wide power supply comes with a wide range of application. Reverse polarity protection which ensures that the device is not damaged if the power supply polarity is reversed. Module also can be powered from interface connectors: RS232, RS485, 2xCAN FDs. They are internally connected.

STM32 Embedded boards were designed with special attention paid to electromagnetic compatibility, a design that has given them a high immunity to external electromagnetic signals which otherwise could have disturbing influence on their working correctly.

The EMC measurements held in a specialized laboratory confirmed low electromagnetic emissions of STM32 Embedded modules, even when displaying dynamic pictures.

Typical surface luminance for a high brightness, IPS TFT displays is 850 cd/m2 which means it is very bright even outdoors. The full viewing angles allow the user to interact with the display in a natural and intuitive way from every side. Please see the datasheet for more features.

A uxTouch display is a specially designed LCD TFT display which has a Projected Capacitive Touch (PTC). They are the perfect choice for your project if you intend to have an interactive design and technology, thanks to their absolute flat design and multi-touch feature.

The 1.8 inch TFT LCD Module Display 128×160 ST7735R SD Card AVR STM32 ARM  is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source lines 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. It 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 crystals, it is possible to make a display system with fewer components.

This 3.2 inch TFT LCD Display module has a resolution of 320 x 240 pixels. The module includes Resistive Touch Screen Panel. SSD1289 is used to control LCD and the touch panel is controlled by XPT2046.The module can be interfaced with any MCU like STM32, AVR and 8051 using the 40 pins breakout header that Include touch panel interface. The module can be driven in 16bit data interface mode.

This LCD Module can be directly plugged into Arduino board using "TFT LCD Adapter Shield for Arduino" shield. The LCD on this module has a has wide viewing angle and a decent contrast ratio.
