# LVGL Demo v9
|
||||
|
||||
[英文版本](./README.md)
|
||||
|
||||
该示例演示了如何移植 LVGL v9 并使用 LVGL 内置的示例进行性能测试。该示例使用了开发板的 MIPI-DSI 接口。基于此示例，可以开发基于 LVGL v9 的应用。
|
||||
|
||||
## 快速入门
|
||||
|
||||
### 准备工作
|
||||
|
||||
* 一块 ESP32-P4-Function-EV-Board 开发板。
|
||||
* 一块由 [EK79007](https://dl.espressif.com/dl/schematics/display_driver_chip_EK79007AD_datasheet.pdf) 芯片驱动的 7 英寸 1024 x 600 LCD 屏幕，配有 32 针 FPC 连接 [适配板](https://dl.espressif.com/dl/schematics/esp32-p4-function-ev-board-lcd-subboard-schematics.pdf) ([LCD 规格](https://dl.espressif.com/dl/schematics/display_datasheet.pdf))。
|
||||
* 用于供电和编程的 USB-C 电缆。
|
||||
* 请参考以下步骤进行连接：
|
||||
* **步骤 1**. 根据下表，将屏幕适配板背面的引脚连接到开发板的相应引脚。
|
||||
|
||||
| 屏幕适配板 | ESP32-P4-Function-EV-Board |
|
||||
| -------------------- | -------------------------- |
|
||||
| 5V（任意一个） | 5V（任意一个） |
|
||||
| GND（任意一个） | GND（任意一个） |
|
||||
| PWM | GPIO26 |
|
||||
| LCD_RST | GPIO27 |
|
||||
|
||||
* **步骤 2**. 通过 `MIPI_DSI` 接口连接 LCD 的 FPC。
|
||||
* **步骤 3**. 使用 USB-C 电缆将 `USB-UART` 端口连接到 PC（用于供电和查看串行输出）。
|
||||
* **步骤 4**. 打开开发板的电源开关。
|
||||
|
||||
### ESP-IDF 要求
|
||||
|
||||
- 此示例支持 ESP-IDF release/v5.3 及以上版本。默认情况下，在 ESP-IDF release/v5.3 上运行。
|
||||
- 请参照 [ESP-IDF 编程指南](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-started/index.html) 设置开发环境。**强烈推荐** 通过 [编译第一个工程](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-started/index.html#id8) 来熟悉 ESP-IDF，并确保环境设置正确。
|
||||
|
||||
### 获取 esp-dev-kits 仓库
|
||||
|
||||
在编译 esp-dev-kits 仓库中的示例之前，请先在终端中运行以下命令，将该仓库克隆到本地：
|
||||
|
||||
```
|
||||
git clone --recursive https://github.com/espressif/esp-dev-kits.git
|
||||
```
|
||||
|
||||
### 配置
|
||||
|
||||
|
||||
运行 ``idf.py menuconfig`` 并修改 ``Board Support Package(ESP32-P4)`` 配置：
|
||||
|
||||
```
|
||||
menuconfig > Component config > Board Support Package
|
||||
```
|
||||
|
||||
## 如何使用示例
|
||||
|
||||
|
||||
### 编译和烧录示例
|
||||
|
||||
编译项目并将其烧录到开发板上，运行监视工具可查看串行端口输出（将 `PORT` 替换为所用开发板的串行端口名）：
|
||||
|
||||
```c
|
||||
idf.py -p PORT flash monitor
|
||||
```
|
||||
|
||||
输入``Ctrl-]`` 可退出串口监视。
|
||||
|
||||
有关配置和使用 ESP-IDF 来编译项目的完整步骤，请参阅 [ESP-IDF 快速入门指南](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/get-started/index.html) 。
