基于小凌派開發(fā)板的迪文屏控制案例

前言：因2個原因?qū)е逻t遲沒有出來想要的效果。原因1：迪文屏的中文字庫問題，對CFG文件及FLASH的分配不熟，導(dǎo)致icl文件覆蓋了字庫文件，在迪文論壇發(fā)帖解決。原因2：串口線不能2節(jié)連接，我測試一直2節(jié)杜邦線連接，導(dǎo)致rk2206發(fā)不出數(shù)據(jù)，用串口demo測試，只有一節(jié)杜邦線電腦才能接到數(shù)據(jù)，弄了一節(jié)將兩個板子連接終于可以了。

迪文屏方面

1、用dgus軟件設(shè)計的歡迎使用界面中生成0號字庫和GBK字庫，如圖1所示，點(diǎn)擊DGUS字庫，出現(xiàn)如圖2所示，生成0號ASCII字庫。

圖1 dgus字庫生成

圖2 生成0號字庫

2、下面就來生成GBK漢字庫，如圖3和圖4所示，生成的24宋體24.bin字庫。

圖3 GBK字庫

圖4 生成漢字庫gbk

3、接下來，新建GUI工程，選一張480*854的背景圖，如圖5所示，保存位置確定。

圖5 新建GUI工程

4、網(wǎng)上找了9張圖標(biāo)，其中自己用位圖編輯了一遍，想多大自己設(shè)置即可，用DWIN ICL生成工具生成圖標(biāo)icl，如圖6所示

圖6 生成圖標(biāo)icl

圖7 導(dǎo)入生成

5、生成背景icl一樣。注意：軟件默認(rèn)背景圖為32.icl，生成CFG文件時需要修改。這個根據(jù)屏的flash大小設(shè)置，我的屏只有8M，因此最大為30，32超出了出現(xiàn)了問題。

6、在背景圖上放置一個圖標(biāo)控件和2個text控件，如圖8所示，text地址設(shè)置2000，另一個設(shè)置2064。設(shè)置TEXT的屬性，ASCII選擇0號字庫，漢字庫選24號字庫，編碼選擇GBK編碼，后面的X和Y點(diǎn)陣設(shè)置為24點(diǎn)陣。這個點(diǎn)陣數(shù)根據(jù)自己字庫生成的點(diǎn)陣設(shè)置。使用出廠的字庫，則分別為0號字庫和12漢字庫。配置為0和12即可。

圖8 放置顯示控件

圖9 text設(shè)置屬性

7、設(shè)置變量圖標(biāo)顯示屬性，如圖10所示，從0開始到8共9個變量圖標(biāo)。

圖10 變量圖標(biāo)顯示設(shè)置

最后生成即可。

T5L51方面

1、因我刷過T5L51，所以串口2調(diào)試協(xié)議不通，只能重刷出廠程序或者自己寫程序。我自己寫的程序，在熊家余老師的串口程序基礎(chǔ)上寫自己的接收代碼，main函數(shù)如下代碼：

#include "sys.h"#include "uart2.h"#include "string.h"
#define FIRST_TXT  "手勢結(jié)果：" //必須以兩個字節(jié)的0x00或者兩個字節(jié)的0xFF為文本結(jié)束標(biāo)記
void main(void){      u16 len;    s16 ges;    u8 text_buf[32]={0};    u16 ic_sta;//存儲ICON值    sys_init();//系統(tǒng)初始化        sys_write_vp(0x2000,FIRST_TXT,sizeof(FIRST_TXT)/2+1);//給第一個文本顯示控件設(shè)置文本內(nèi)容        uart2_init(115200);//初始化串口2        while(1)    {          IF(uart2_rx_sta&UART2_PACKET_OK)//接受到了串口數(shù)據(jù)包        {            len = uart2_rx_sta&UART2_PACKET_LEN;//得到串口數(shù)據(jù)包的長度,不包含"
"或者'
'結(jié)束符的長度                        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);//同時把數(shù)據(jù)包顯示到界面上                        uart2_rx_sta = 0;//清0代表處理掉了此串口包        }    }}

測試：測試的時候總是控制不了，用小凌派的串口發(fā)給電腦串口，也沒有。不應(yīng)該，人家廠家肯定沒問題。本來2節(jié)杜邦線，改成了1節(jié)杜邦線，可以了。
