Hangxin ACM32G103 Development Board Review 06 1.28 Round Screen LVGL Transplantation [Copy link]

# Hangxin ACM32G103 Development Board Review 06 1.28 Circular Screen LVGL Transplantation## Reference Transplantation Tutorial https://bbs.eeworld.com.cn/thread-1270136-1-1.html ## Software and Hardware Platform 1. Hangxin ACM32G103 Development Board 2. 1.28-inch Circular Color TFT Display HD IPS Module 240X240 SPI Interface GC9A01 Driver Chip 3. LVGL V8.3.1 Source Code### LVGL LVGL (Light and Versatile Graphics Library) is a free open source graphics library that provides the creation of embedded GUIs with easy-to-use graphic elements, beautiful visual effects and low memory usage. LVGL is a free open source graphics library with rich components, advanced graphics features, support for multiple input devices, multiple languages and hardware independence. Next, let's take a look at the main features of the LVGL graphics user library: Powerful building blocks: buttons, charts, lists, sliders, images and other components. With advanced graphics properties: Advanced graphics with animation, anti-aliasing, opacity, smooth scrolling. Supports various input devices: such as touch, mouse, keyboard, encoder. Supports multiple languages: UTF-8 encoding. Supports multiple displays: It can use multiple TFT or monochrome displays at the same time. Supports multiple style properties: It has fully customizable graphic elements with CSS-like styles. Hardware independent: It works with any microcontroller or display. Scalability: It can run with small memory (minimum 64 kB flash, 16 kB RAM for MCU). Supports operating system, external memory and GPU (not required). With advanced graphics effects: Single frame buffer operation is possible. Written in pure C: Written in C language for maximum compatibility. ## Quick porting process 1. Modify the existing ACM32G103RCT6 TFT bare metal porting LVGL project template and add the LVGL source code file

 5. Add LCD screen initialization function, drawing function ```c /********************** * STATIC FUNCTIONS **********************/ /*Initialize your display and the required peripherals.*/ static void disp_init(void) { /*You code here*/ LCD_Init(); LCD_BLK_SET;//Control the backlight through IO} volatile bool disp_flush_enabled = true; /* Enable updating the screen (the flushing process) when disp_flush() is called by LVGL */ void disp_enable_update(void) { disp_ flush_enabled = true; } /* Disable updating the screen (the flushing process) when disp_flush() is called by LVGL */ void disp_disable_update(void) { disp_flush_enabled = false; } /*Flush the content of the internal buffer the specific area on the display *You can use DMA or any hardware acceleration to do this operation in the background but *'lv_disp_flush_ready()' has to be called when finished. */ static void disp_flush(lv_disp_drv_t * disp_drv, const lv_area_t * area, lv_color_t * color_p) { if(disp_flush_enabled) { /*The most simple case (but also the slowest) to put all pixels to the screen one-by-one*/ uint16_t x,y; for(y = area->y1; y <= area->y2; y++) { for(x = area->x1; lv_disp_flush_ready(disp_drv); } ``` Basically, the connection between a screen and LVGL is completed. When you change to another screen, the operation is basically the same, provided that the screen driver file must be successfully adapted. ### Case test 1. Official case demo function Add official demo code and open LV_USE_DEMO_WIDGETS macro definition
