melis内嵌了很多测试示例,今天测试了一下显示部分的命令,开发板是mango-MQ-r-F133。

1.配置将显示测试源码包含进工程(默认是包含了)

2.不要启动melis桌面系统

修改《startup.sh》(位于目录 D1s-Melis/projects/d1s-mq/data/UDISK/startup.sh):
Melis4.0[D1s]:4.测试笔记 - 内嵌的显示命令_第2张图片
经过上面的修改,再编译,烧录,运行,就只能通过串口命令行和Melis的uart0进行交互。
在控制台输入 help,出现可用的全部命令:

其中和显示相关的有几个命令:
在这里插入图片描述

3.开始测试

3.1 disp 命令

disp命令的相关源码位于 《D1s-Melis/ekernel/drivers/hal/source/disp2/disp/disp_debug.c》 文件里面:
在这里插入图片描述

命令 参数 含义
disp 不带参数 打印显示信息
disp -c colorbar 颜色测试
disp -r 打印显示相关的寄存器数内容
disp -s switch display ,切换显示接口
disp -d dump de data
disp -e enhance,设置 enhance相关参数
disp -b backlight,背光设置

3.1.1 disp不带参数时,打印显示信息:

msh />disp

mgr0: 800x480 fmt[rgb] cs[0x204] range[full] eotf[0x4] bits[8bits] err[0] force_sync[0] unblank direct_show[false]

3.1.2 disp -c 0 8 测试4种颜色

# disp -c 表示颜色测试,下面的 0表示screen0,8 表示显示内嵌的4种颜色
disp -c 0 8 

测试效果:

源码中对最后面一个参数的注释:

	/*val:*/
	/*0:DE-->tcon-->other interface*/
	/*1-7:tcon or edp or other device's builtin patten*/
	/*for tcon:*/
	/*1:color bar*/
	/*2:grayscale check*/
	/*3:black and white check*/
	/*4:all 0*/
	/*5:all 1*/
	/*6:reserve*/
	/*7:Gridding*/
	/*for edp:*/
	/*1:colorbar*/
	/*2:mosaic*/

测试下面的命令:

disp -c 0 1 

效果:

继续测试:

disp -c 0 2 

效果,有些灰阶:

继续测试:

disp -c 0 3 

效果和 disp -c 0 2 接近,纯灰,没有阶梯感。
disp -c 0 4 是全部黑色, disp -c 0 5 是全部白色。
disp -c 0 6 和disp -c 0 8 一样。
继续测试:

disp -c 0 7

3.2 disp_layer_cfg 命令

这个命令的源文件是 《D1s-Melis/ekernel/drivers/hal/test/disp2/disp_layer_cfg.c》
在这里插入图片描述
本命令用于对下面结构体赋值:

struct test_layer_cfg
{
	int screen_id;
	int layer_id;
	int mem_id;
	struct disp_layer_config layer_cfg;
	int addr_map;
	int width,height;//screen size
	rt_device_t dispfh;//device node handle
	FILE *fh;//picture resource file handle
	void* mem;
	int clear;//is clear layer
	int fullscreen;//is full screen
	char filename[32];
};
struct disp_layer_config {
	struct disp_layer_info info;
	bool enable;
	unsigned int channel;
	unsigned int layer_id;
};
struct disp_layer_info {
	enum disp_layer_mode mode;
	unsigned char zorder;
	/* 0: pixel alpha;  1: global alpha;  2: global pixel alpha */
	unsigned char alpha_mode;
	unsigned char alpha_value;	/* global alpha value */
	struct disp_rect screen_win;	/* display window on the screen */
	bool b_trd_out;		/* 3d display */
	enum disp_3d_out_mode out_trd_mode;	/* 3d display mode */
	union {
		unsigned int color;	/* valid when LAYER_MODE_COLOR */
		struct disp_fb_info fb;	/* valid when LAYER_MODE_BUFFER */
	};

	unsigned int id; /* frame id, the id of frame display currently */
};
命令 参数 设置变量
disp_layer_cfg -ch test_layer_cfg.screen_id
disp_layer_cfg -mem_id test_layer_cfg. mem_id
disp_layer_cfg -channel_id test_layer_cfg. layer_cfg.channel
disp_layer_cfg -in_fb test_layer_cfg. layer_cfg.info.fb.format
disp_layer_cfg -layer_mode test_layer_cfg.layer_cfg.info.mode
disp_layer_cfg -alpha test_layer_cfg.layer_cfg.info.alpha_value
disp_layer_cfg -screen_win test_layer_cfg. layer_cfg.info.screen_win
disp_layer_cfg -layer_id layer_cfg.layer_id

这个命令用到下面的实例:

disp_layer_cfg  -in_fb 0 800 480 0 0 800 480 4

对应源码:

		if ( ! strcmp(argv[i], "-in_fb")) {
			if (argc > i+8) {
				i++;
				p->layer_cfg.info.fb.format = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.size[0].width = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.size[0].height = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.crop.x = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.crop.y = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.crop.width = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.crop.height = atoi(argv[i]);
				i++;
				p->layer_cfg.info.fb.align[0] = atoi(argv[i]);
			}	else {
				printf("-in_fb para err!\n\n");
				err ++;
			}
		}

3.3 disp_mem 对显示内存写入内容

命令 参数 设置变量
disp_mem -mem_id 显示内存索引
disp_mem -size 显示范围的宽和高
disp_mem -file 将文件中的数据写入显示内存,如果文件名以rbg三个字母中的一个开头,就全部显示单一颜色,r=红,g=绿,b=蓝

本命令要配合上一节的disp_layer_cfg 命令,依次输入:

#	1.对显示内存全部填充红色
disp_mem -mem_id 0 -size 800 480  -file  r
#	2.配置显示图层
disp_layer_cfg  -in_fb 0 800 480 0 0 800 480 4

显示效果:

3.3.1 disp_mem 测试源码有错误,更正

源码文件路径 《D1s-Melis/ekernel/drivers/hal/test/disp2/disp_mem.c》
Melis4.0[D1s]:4.测试笔记 - 内嵌的显示命令_第8张图片
修改为:

		while(count--) {
				*(tmp + 3) = 0xff;//A
				*(tmp + 2) = filename[0]=='r'?0xff:0;//R
				*(tmp + 1) = filename[0]=='g'?0xff:0;//G
				*(tmp + 0) = filename[0]=='b'?0xff:0;//B
				tmp+=4;
		}
