TFT_LCD_LVGL

Overview

This application is a demonstration of LVGL functionalities using the WM IoT SDK. It illustrates how to initialize the TFT LCD device and create an LVGL DEMO Task for the initialization of the LVGL module, showcasing various native LVGL demo scenarios such as: Widgets, Music Player, Benchmark, Stress etc. The program interfaces with the TFT LCD module via the SDIO (SPI mode) and utilizes DMA/CPU Polling for communication. The hardware configurations are detailed in the Device Table, which encompasses pin definitions, frequency settings for SDIO (SPI mode), and additional pin configurations for the LCD device.

Building and flashing

Example Location：examples\tft_lcd\tft_lcd_lvgl

The selection of demo scenarios is made in the lv_confs.h header file of the LVGL component by enabling the corresponding macro definition switch, for example: enabling LV_USE_DEMO_MUSIC. It should be noted that to avoid conflicts, two or more demo scenario macro definition switches must not be enabled simultaneously.
