mango-MQ-R基于Melis移植lvgl

bigfly LV 5

1.下载lvgl源码到《D1s-Melis/ekernel/drivers/hal/test/disp2》目录
我使用的源码是https://github.com/lvgl/lv_port_pc_eclipse，克隆到 D1s-Melis/ekernel/drivers/hal/test/disp2 目录。然后在 D1s-Melis/ekernel/drivers/hal/test/disp2/lv_port_pc_eclipse》目录下建立一个Makefile，把全部的C文件都包含进来编译的。这是因为lvgl的所有非必要的C文件都可以通过宏定义配置是否编译。例如lv_bmp.c里面的代码是否编译，取决于宏定义

LV_USE_BMP：

为了简单起见，很多非必要的组件我都没有包含进来，详情见 lv_conf.h 。

1.1 修改Makefile

先在disp2目录下的Makefile把子目录disp2/lv_port_pc_eclipse包含进来：

subdir-ccflags-y +=	-I$(srctree)/ekernel/drivers/include \
			-I$(srctree)/ekernel/core/rt-thread/include \
			-I$(srctree)/ekernel/drivers/drv/source/disp2/soc
obj-y +=  disp_layer_cfg.o disp_mem_hwd.o
#disp_mem.o
obj-y += disp_layer_alpha_test.o
obj-y += disp_layer_scal_test.o
obj-y += disp_layer_format_test.o
obj-y += disp_lbc_test.o
obj-y += lv_port_pc_eclipse/

再将isp2/lv_port_pc_eclipse目录下的Makefile改为下面内容（节选）：

1.2 快速测试Makefile修改是否有效
把主函数中和硬件相关的显示，输入等初始化代码屏蔽，main改为lv_main，并把lv_main变成一个命令：

int lv_main(int argc, char **argv)
{
  //(void *)argc; /*Unused*/  //(void)argv; /*Unused*/
  printf("lv_main.");
#if   0
  /*Initialize LVGL*/
  lv_init();

  /*Create a default group for keyboard navigation*/
  lv_group_set_default(lv_group_create());

  /*Initialize the HAL (display, input devices, tick) for LVGL*/
  hal_init();
.....
#endif
  return 0;
}
static lv_disp_t * hal_init(void  )
{
#if 0
    disp_layer_cfg_def();

    static lv_disp_draw_buf_t draw_buf;

    lv_disp_draw_buf_init(&draw_buf, disp_buf1, disp_buf2, HOR_RES * VER_RES);

    static lv_disp_drv_t disp_drv;
    lv_disp_drv_init(&disp_drv);
......   
    lv_disp_drv_register(&disp_drv);
#endif
	lv_disp_t * disp = NULL;
  	return disp;
}
FINSH_FUNCTION_EXPORT_ALIAS(lv_main, lv_main, lv_main );

编译通过，烧录测试。输入help，可以看到lv_main命令,输入lv_main，打印“lv_main”：

msh />help
RT-Thread shell commands:
......
lv_main          - lv_main
......
msh />lv_main
lv_main

2.移植刷新显示内存函数dummy_flush_cb
只要往显存地址 mem = g_disp_mm[mem_id].info_base里面填写像素数据，就可以得到我们要显示的内容，把这个地址传给一个全局变量，在lvgl中使用这个全局变量即可。
于是我们在disp_mem源码所在的C文件声明一个全局变量：

uint32_t * g_p_mem_base;

把显存地址传给g_p_mem_base：

g_p_mem_base = g_disp_mm[mem_id].info_base;

有了这个地址，我们就可以编写自己的显示回调函数：

#define HOR_RES 800
#define VER_RES 480
extern  uint32_t * g_p_mem_base;
#define line_length 800 * sizeof(rt_uint32_t) / 4
static void dummy_flush_cb(lv_disp_drv_t * disp_drv, const lv_area_t * area, lv_color_t * color_p)
{
    /*Truncate the area to the screen*/
    int32_t act_x1 = area->x1 < 0 ? 0 : area->x1;
    int32_t act_y1 = area->y1 < 0 ? 0 : area->y1;
    int32_t act_x2 =        area->x2 > (int32_t)HOR_RES - 1 ? (int32_t)HOR_RES - 1 : area->x2;
    int32_t act_y2 =        area->y2 > (int32_t)VER_RES - 1 ? (int32_t)VER_RES - 1 : area->y2;

    lv_coord_t w = (act_x2 - act_x1 + 1);

    long int location = 0;

    /* 32 bit per pixel */
    uint32_t *fbp32 = (uint32_t *)g_p_mem_base;
    uint32_t y;
    for (y = act_y1; y <= act_y2; y++)
    {
        location = act_x1 + y * line_length;
        rt_memcpy(&fbp32[location], (uint32_t *)color_p, (act_x2 - act_x1 + 1) * 4);
        color_p += w;
    }   
        
    lv_disp_flush_ready(disp_drv);
}
static lv_color_t disp_buf1[HOR_RES * VER_RES];
static lv_color_t disp_buf2[HOR_RES * VER_RES];
int disp_layer_cfg_def(void);
static lv_disp_t * hal_init(void  )
{
#if 1
    disp_layer_cfg_def();

    static lv_disp_draw_buf_t draw_buf;

    lv_disp_draw_buf_init(&draw_buf, disp_buf1, disp_buf2, HOR_RES * VER_RES);

    static lv_disp_drv_t disp_drv;
    lv_disp_drv_init(&disp_drv);
    disp_drv.draw_buf = &draw_buf;
    disp_drv.flush_cb = dummy_flush_cb;
    disp_drv.hor_res = HOR_RES;
    disp_drv.ver_res = VER_RES;
    lv_disp_drv_register(&disp_drv);
#endif
	lv_disp_t * disp = NULL;
  return disp;
}

再make编译，通过。

3.创建一个定时器调用lvgl心跳lv_tick_inc()
Melis使用rt-thread内核，rt-thread的节拍由宏定义 CONFIG_HZ决定:

#define RT_TICK_PER_SECOND  CONFIG_HZ

CONFIG_HZ通过命令 make menuconfig 配置：

这里是200Hz，也就是一个时钟节拍为5ms。

static rt_timer_t timer1;      
//      lv_tick_inc(5);
static lv_disp_t * hal_init(void  )
{
#if 1
    /* 创建定时器1  周期定时器 */
    timer1 = rt_timer_create("timer1", 
    						lv_tick_inc,	//	回调函数
                             5,				//	回调函数的传入参数
                             1,	//	一个时钟节拍调用一次回调函数，具体是5ms
                             RT_TIMER_FLAG_PERIODIC);
    /* 启动定时器1 */
    if (timer1 != RT_NULL)
        rt_timer_start(timer1);

    disp_layer_cfg_def();

......
#endif
	lv_disp_t * disp = NULL;
  return disp;
}

lv_timer_handler()调用间隔是10ms，而lv_tick_inc()调用间隔是5ms，这样比较合理。

[partition]
    name         = UDISK
    ;size = flash size - (boot0 + mbr) size - env - env-redund - ROOTFS
    ;8(or 16) * 1024 * 2 - 64 * 2 - 5632 - 8 - 8 - 10240
    ;size         = 20336
    ;downloadfile = "data_udisk.fex"
    user_type    = 0x8000

再次pack打包成功。烧录运行，输入lv_main命令：

msh />lv_main

5.设置开机启动
修改startup.sh（位于目录 D1s-Melis/projects/d1s-mq/data/UDISK/startup.sh）:

echo "Execute startup script begin.............."

#insmod d:\mod\display.mod
#insmod d:\mod\orange.mod
#insmod d:\apps\desktop.mod
lv_main
echo "...............Execute startup script end"

6.源码下载
源码没有startup.sh 和 melis_pkg_nor.fex ，这两个文件的修改比较简单。
源码链接：https://gitee.com/huangweide001/linux-d1-h-test/tree/master/disp2
源码包含了可以直接烧录的img文件 melis_d1s-mq_uart0_8Mnor_lvgl.img 。
