0、前言
LVGL官方已经提供了RA8DA1的port，见：
LVGL ported to Renesas EK-RA8D1
GitHub - lvgl/lv_port_renesas_ek-ra8d1_gcc
但是此例子是针对EK-RA8D1开发板，10寸显示屏，如果直接用于CPKCOR-RA8D1核心板+扩展板显然不行。
另外，demo中cpkhmi_ra8d1b开发板也提供了3个LVGL例子：
- lvgl_v8_cpkhmi_ra8d1_ep
- lvgl_v9_cpkhmi_ra8d1_ep
- lvgl_v9_freertos_cpkhmi_ra8d1_ep
由于开发板存在差异，同样如果直接拿来，仍然不能使用。
通过lvgl官方的例子发现在lvgl.9.3.0已经集成到了fsp.6.0.0中,
在C:\Users\用户名.eclipse\com.renesas.platform_1713588285\internal\projectgen\ra\packs中可以看到对应pack:
LVGL.lvgl.9.3.0+renesas.0.fsp.6.0.0.pack
所以如果已经安装了fsp.6.0.0，就具备了下面从头开始搭建lvgl的条件。
一、配置
1、新建工程
基于FSP版本6.0.0；核心板
2、Pin配置修改
”Select Pin Configuration“-->“Manage configurations"可以导入、导出pin配置
由于Pin配置比较繁琐容易出错，可以从cpkexp_ekra8x1开发板例程中导出Pin配置然后导入到工程。
点击“Manage configurations"，Import之前Pin配置文件：CPKCPR MIPI config
选中CPKCPR MIPI config，右边勾选Generate data，这样就完成了pin配置文件的替换。
3、STACKS中加入LVGL
刚加入LVGL后，三个模块是红色的。
完成以下工作消除红色：
配置LCDCLK时钟：
修改Heap size
修改为非rtos模式
4、BSP中是能SDARAM Support
5、LVGL属性中增加自定义文件
lv_conf_user.h
6、g_display0 Graphics属性
参数参考扩展板例程
7、g_mipi_dsi0 MIPI Display属性
新建MIPI Display
修改Lane为1
二、程序部分
1、board_init.c
调用了LVGL PORT相关函数，这部分函数FSP已经实现了。
#include"board_init.h"
#include"lvgl.h"
#include"common_data.h"
#if LV_USE_DRAW_DAVE2D
#define DIRECT_MODE 1
#else
#define DIRECT_MODE 0
#endif
void board_init(void)
{
#if DIRECT_MODE
fsp_err_t err;
err = RM_LVGL_PORT_Open(&g_lvgl_port_ctrl, &g_lvgl_port_cfg);
if (FSP_SUCCESS != err)
{
__BKPT(0);
}
#else
staticuint8_t partial_draw_buf[64*1024] BSP_PLACE_IN_SECTION(".dtcm_bss") BSP_ALIGN_VARIABLE(1024);
lv_display_t * disp = lv_renesas_glcdc_partial_create(partial_draw_buf, NULL, sizeof(partial_draw_buf));
#endif
#if DIRECT_MODE lv_display_set_default(g_lvgl_port_ctrl.p_lv_display);
#else
lv_display_set_default(disp);
#endif
}
2、dsi_configuration_data.c
扩展板上屏幕初始化参数
#include "dsi_layer.h"
LCD_setting_table lcd_init_focuslcd[] =
