stm32 tft lcd in stock

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.

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

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.

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.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).

This 7 inch TFT LCD display module has super stability. The module uses the driving scheme of CPLD + SDRAM, which far more superior than SSD1963 and RA8875. Solve the problem of bad immunity, death and white screen from SSD1963.

This 7 inch TFT LCD display module has good simplicity. Not need an initializer, what have to do is reset. You can use 5 register command to control it. Greatly thin the code, reducing the debugging difficult and error rate.

This 7 inch TFT LCD display module has good speed. The respond speed of W/R cycle can be up to 200ns. The fastest full screen refresh rate is 13 frames. 8M SDRAM correspond to 8 pages display cache. The display registers and RW one is set independently. Display page and RW page also can be in which data can be written in the background. Just using one command to change screenful display data instantly. Far more superior than RA8875.

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.
