前言：因2个原因导致迟迟没有出来想要的效果。原因1：迪文屏的中文字库问题，对CFG文件及FLASH的分配不熟，导致icl文件覆盖了字库文件，在迪文论坛发帖解决。原因2：串口线不能2节连接，我测试一直2节杜邦线连接，导致rk2206发不出数据，用串口demo测试，只有一节杜邦线电脑才能接到数据，弄了一节将两个板子连接终于可以了。
迪文屏方面：
1、用dgus软件设计的欢迎使用界面中生成0号字库和GBK字库，如图1所示，点击DGUS字库，出现如图2所示，生成0号ASCII字库。
图1 dgus字库生成
图2 生成0号字库
2、下面就来生成GBK汉字库，如图3和图4所示，生成的24宋体24.bin字库。
图3 GBK字库
图4生成汉字库gbk
3、接下来，新建GUI工程，选一张480*854的背景图，如图5所示，保存位置确定。
图5 新建GUI工程
4、网上找了9张图标，其中自己用位图编辑了一遍，想多大自己设置即可，用DWIN ICL生成工具生成图标icl，如图6所示
图6 生成图标icl
图7 导入生成
5、生成背景icl一样。注意：软件默认背景图为32.icl，生成CFG文件时需要修改。这个根据屏的flash大小设置，我的屏只有8M，因此最大为30，32超出了出现了问题。
6、在背景图上放置一个图标控件和2个text控件，如图8所示，text地址设置2000，另一个设置2064。设置TEXT的属性，ASCII选择0号字库，汉字库选24号字库，编码选择GBK编码，后面的X和Y点阵设置为24点阵。这个点阵数根据自己字库生成的点阵设置。使用出厂的字库，则分别为0号字库和12汉字库。配置为0和12即可。
图8 放置显示控件
图9 text设置属性
7、设置变量图标显示属性，如图10所示，从0开始到8共9个变量图标。
图10 变量图标显示设置
8、最后生成即可。
T5L51方面：
1、因我刷过T5L51，所以串口2调试协议不通，只能重刷出厂程序或者自己写程序。我自己写的程序，在熊家余老师的串口程序基础上写自己的接收代码，main函数如下代码：
- #include "sys.h"
- #include "uart2.h"
- #include "string.h"
- #define FIRST_TXT "手势结果：\0\0" //必须以两个字节的0x00或者两个字节的0xFF为文本结束标记
- void main(void)
- {
- u16 len;
- s16 ges;
- u8 text_buf[32]={0};
- u16 ic_sta;//存储ICON值
- sys_init();//系统初始化
-
- sys_write_vp(0x2000,FIRST_TXT,sizeof(FIRST_TXT)/2+1);//给第一个文本显示控件设置文本内容
-
- uart2_init(115200);//初始化串口2
-
- while(1)
- {
- if(uart2_rx_sta&UART2_PACKET_OK)//接受到了串口数据包
- {
- len = uart2_rx_sta&UART2_PACKET_LEN;//得到串口数据包的长度,不包含"rn"或者'n'结束符的长度
-
- ges = uart2_buf[0]+uart2_buf[1]*256;
- switch(ges)
- {
- case 1:
- ic_sta = 0;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_UP:0x%x",ges);
- break;
- case 2:
- ic_sta = 1;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_DOWN:0x%x",ges);
- break;
- case 4:
- ic_sta = 2;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_LEFT:0x%x",ges);
- break;
- case 8:
- ic_sta = 3;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_RIGHT:0x%x",ges);
- break;
- case 16:
- ic_sta = 4;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_FORWARD:0x%x",ges);
- break;
- case 32:
- ic_sta = 5;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_BACKWARD:0x%x",ges);
- break;
- case 64:
- ic_sta = 6;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_CLOCKWISE:0x%x",ges);
- break;
- case 128:
- ic_sta = 7;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_COUNT_CLOCKWISE:0x%x",ges);
- break;
- case 256:
- ic_sta = 8;
- sys_write_vp(0x1000,(u8*)&ic_sta,1);
- sprintf(text_buf,"GES_WAVE:0x%x",ges);
- break;
- default:
-
- break;
- }
- len = strlen(text_buf);
- text_buf[len++] = 0;
- text_buf[len++] = 0;
- sys_write_vp(0x2064,text_buf,len/2+1);//同时把数据包显示到界面上
-
- uart2_rx_sta = 0;//清0代表处理掉了此串口包
- }
- }
- }
小凌派方面：
根据手势demo将uart的demo加入到手势demo.rar中，如下所示

测试方面：测试的时候总是控制不了，用小凌派的串口发给电脑串口，也没有。不应该，人家厂家肯定没问题。本来2节杜邦线，改成了1节杜邦线，可以了。
测试效果如视频所示。
