(1) GLCD adopts SPI four-wire communication interface, and the MCU interacts with instructions, such as displaying a 100100 rectangle (10000 pixels), the MCU only needs to send coordinates and color values to GLCD, 16 bytes. (2) emWin is an embedded GUI graphics library of the German SEGGER company. The concept of the GUI graphics library is as if it is a software platform. We follow the method provided by it to run a user interface program written in C language on emWin. You can display the interface we need.(3) The emWin (including user interface program) and GLCD running in the MCU interact with each other through instructions. The GLCD is responsible for storing fonts and pictures, as well as receiving and executing drawing commands from emWin and displaying them on the screen; as to how they pass instructions Interaction, emWin driver floor has been done (no user care), users only need to care about how to use the C language interface program can be.
SPI four-wire communication, through the command control display, simple and high-speed, fast interface refresh, suitable for big data display. Based on the emWin application, configuration, drag-and-drop man-machine interface design, simulation and rapid design interface, low threshold, and C language can be used. Hardware 2D Graphics Acceleration Coprocessor to display BMP pictures, text, rectangles, circles, lines, points, zones in hardware DMA. Domain fill, area copy, video copy, and more. Large-capacity Nand-Flash is used as storage for fonts and pictures (using the same download line as a USB stick).Double video memory automatically manages the design to avoid "drawing curtains" when the screen is updated. Instruction buffering mechanism, realizing zero burden on the user's CPU.
24-bit color (RGB888) display, the network material is used directly and the picture is not distorted. Based on FAT/FAT32 file system management fonts and pictures, support for multi-level folders (subdirectories), when the number of fonts and pictures is very large.
User management is very convenient. Users can create their own fonts and support fonts generated by various font tools. Font display encoding format supports ASCII, GB2312, GBK, BIG5, UNICODE (width/height), and supports text clipping display. Supports 16bbp (RGB565)/24bbp (RGB888) bitmaps in BMP format for image cropping, transparent display, and transparent animation.Transparent RTC clock display (display style user can be customized), transparent display allows users to superimpose various clock backgrounds. Supports PS/2 mouse and PS/2 keyboard (Most USB mouse/keyboards on the market are compatible with both USB and PS/2 protocols). Supports 4x6 matrix keyboard (only 4x4 matrix keyboard is supported when PS/2 keyboard is enabled). FPGA single-chip industrial-grade solution with strong immunity and stable system.
(1) Use the GUIBuilder configuration tool on the PC to make the emWin interface and generate the interface C file. (2) Add the generated interface C file to the Code::Blocks software simulation interface. (3) Add the prepared interface C file to the Keil MDK project and compile the project. (4) Download to STM32 MCU to run.
