【开源】迪文串口屏与小凌派rk2206通信控制
屏幕型号T5L DMG85480F050_01WTCZ021、迪文GUI设计，包含一个变量图标控制和2个text显示控件。注意中英文字库问题，字库可用DWIN DGUS软件的DGUS配置工具中的DGUS字库工具，生成0号字库，主要英文、数字和符号，中文字库用GBK编码制作字库。
2、迪文C51设计，串口2自定义处理小凌派rk2206的串口数据，并对显示控件进行控制。用keil开发C51单片机程序，主要main代码如下：
#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;
u8text_buf={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+uart2_buf*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 = 0;
text_buf = 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
}
}
}
完整代码附件上传。KEIL工程我加入了直接生成T5L51.bin文件功能，大家可以打开工程查看。目标文件修改需要修改bat文件。
3、小凌派rk2206手势控制传感器结果，由串口发送给迪文串口屏的串口2.小凌派跑的是鸿蒙系统，没有的可以使用其他对接开发板即可，也可用另一51单片机串口发送控制，用按键即可，都可以。手里正好有这个板子。
