【FireBeetle 2 ESP32 C6开发板】7、适配lvgl 9.1-- 添加默认板型配置，运行程序 [复制链接]

<div class='showpostmsg'>### 前言
lvgl已经出到9.x版本了，github上的lv_port_esp32还是7.x版本，由于我自己有Linux和esp32两种设备的开发需求，esp32的RAM和Flash也不算小，
我手上的板子也不少，干脆修改一下默认板型的屏幕配置吧。

#### 修改Kconfig配置
添加两个板型的屏幕默认配置，LV_PREDEFINED_DISPLAY_WAVESHARE_169 和 LV_PREDEFINED_DISPLAY_BOARD_169 
添加这些配置之后，就可以直接在菜单里选择对应的板型，然后就可以直接切换板子配置，编译运行了。
以下就是修改后生成的patch文件

#### 菜单展示
修改完以后，可以看到菜单里增加了对应板型的配置。也可以看到选择了对应板型之后，配置文件也正确选择了屏幕spi的引脚。

制作完毕后编译，烧录到开发板上，可以看到lvgl测试程序已经顺利跑起来了。
