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
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"\r\n"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: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。
