如何通過RA8889 / RA8876來顯示文字？

UI界面需求最大的兩個功能，第一個是顯示圖形，第二個是顯示文字。文字部分有ASCII和中文，或者是多國語言，下面我們就專門針對RA8889如何顯示文字展開介紹。

本章要介紹如何自建中文字庫，以及單片機如何控制RA8889進行調用并顯示。

本篇要展現(xiàn)的內容比較豐富，篇幅較長，需要多些耐心閱讀。

三種文字顯示方法的優(yōu)缺比較：


通過上圖比較，自建字庫除了顯示速度會慢一些，優(yōu)勢還是很大，設計靈活度也很高，同時還可以節(jié)省專用字庫芯片的成本，具有一定的經(jīng)效益，值得多加參考！

下面開始介紹單片機如何控制RA8889來驅動彩屏顯示文字，這里主要是針對顯示中文字體進行展開說明，若還有其他國家的字體也可以借鑒該方法進行設計，有興趣的C友們可留言進行探討。

一、需求的中文字數(shù)不多，采用以下方法

  • 自建點陣字碼表；
  • 單片機獲取字碼數(shù)據(jù)，按點寫入顯存，同時指定前景、背景及透明色。

框架圖：

調用函數(shù)：

void User_Font_Demo(void)
{
    Show_User_Font(25, 32, 350, 180, 0, color65k_red, color65k_green, "菱致電子瑞佑科技");
    Show_User_Font(25, 32, 260, 260, 1, color65k_black, color65k_red, "單片機驅動彩色液晶屏極簡方案");
    delay_seconds(3);
}


子函數(shù)：

void Show_User_Font(
    unsigned int font_lib_size // 自建字庫數(shù)組的文字個數(shù)
    ,
    unsigned int font_size // 字模大小，比如32*32點陣寫32
    ,
    unsigned short x // 顯示窗口的x軸坐標
    ,
    unsigned short y // 顯示窗口的y軸坐標
    ,
    int Chroma_key // 是否透明：0-不透明 1-透明色
    ,
    unsigned long Foreground_color // 前景色
    ,
    unsigned long Background_color // 背景色
    ,
    const unsigned char *str // 字符串
)
{
    unsigned int i, j = 0;
    unsigned int k, len; // len；字符串的長度
    unsigned char hanziCode[128];
    unsigned char strfont_0, strfont_1, Index_0, Index_1;

    Goto_Pixel_XY(x, y);
    strcpy((char *)hanziCode, str);
    len = strlen(hanziCode) / 2; // 一個中文漢字占兩個字節(jié)

    for (k = 0; k < len; k++) {
        strfont_0 = *(hanziCode + j); // 字符值
        j++;
        strfont_1 = *(hanziCode + j);
        j++;
        for (i = 0; i < font_lib_size; i++) {
            Index_0 = code_GB_32[i].Index[0]; // 取出字庫數(shù)組中漢字內碼索引值
            Index_1 = code_GB_32[i].Index[1];
            if (strfont_0 == Index_0 && strfont_1 == Index_1) // 比較字符值與漢字內碼索引值
            {
                if (Chroma_key == 1)
                    BTE_MCU_Write_ColorExpansion_Chroma_key_MCU_8bit(0, canvas_image_width, x + font_size * k, y, font_size, font_size, Foreground_color, code_GB_32[i].Msk); // 透明色
                if (Chroma_key == 0)
                    BTE_MCU_Write_ColorExpansion_MCU_8bit(0, canvas_image_width, x + font_size * k, y, font_size, font_size, Foreground_color, Background_color, code_GB_32[i].Msk); // 非透明色
                break;
            }
        }
    }
}


上例中BTE_MCU_Write_ColorExpansion_Chroma_key_MCU_8bit和BTE_MCU_Write_ColorExpansion_MCU_8bit為瑞佑官方API接口程序，本文暫不綴述。實例顯示效果如下圖：


自建漢字每個字皆可單獨取模，因此可展現(xiàn)不同字體。

附上自建漢字字模數(shù)組，漢字取模軟件為橫向8點左高位，從左到右，從上到下排列。取模的軟件可以和我們聯(lián)絡獲取。

// ------------------  漢字字模的數(shù)據(jù)結構定義 ------------------------ //
typedef struct typFNT_GB32                // 漢字字模數(shù)據(jù)結構
{
       signed char Index[2];              // 漢字內碼索引
       char Msk[128];                     // 點陣碼數(shù)據(jù)：32*32/8=128
};

二、需求全套中文，字數(shù)多必然需要更多存儲空間，那么可以存放到FLASH中。

這里所講的FLASH是與RA8889 / RA8876連接的，一般是用來存放UI所需的圖資，也可以將字庫存放于此，這樣不需要增加成本，但可節(jié)省掉外接字庫芯片的成本！

框架圖：




自建字庫不限套數(shù)，單套占用容量不大，比如24x24點是576KB。這里提供的算法是通過RA8889 / RA8876的DMA（Direct Memory Access）功能獲取到字符數(shù)據(jù)，再通過BTE（Block Transfer Engine）功能將文字顯示出來。經(jīng)過優(yōu)化，目前顯示速度還算不錯，參考下方展示視頻：




調用代碼范例：

    // 演示自建字庫調用
    BTE_Solid_Fill(display_address, canvas_image_width, 0, 0, 0x01, LCD_width, LCD_height); // 緩存顯示區(qū)域：填充底色0x01；display_address此處自定義為canvas_image_width*LCD_height*24/8
    SPI_NOR_initial_DMA(0, Font_BUS, Font_CS, 1, 0);    //FLASH初始化
    User_Def_Font_Initial();    //顯示自定義文字初始化

    Font_Size_ChromaKey_ForeColor_BackColor(24, 1, color256_red, color256_white);    //字體參數(shù)設定(最多256色)
    Show_User_Def_String("自建漢字庫：宋體１６ｘ１６演示", songti16, 16, 2, 50, 20);    //顯示字符串
    Show_User_Def_String("自建漢字庫：楷體１６ｘ１６演示", kaiti16, 16, 2, 50, 45);    //顯示字符串
    Show_User_Def_String("自建漢字庫：黑體１６ｘ１６演示", heiti16, 16, 2, 50, 70);    //顯示字符串

    Font_Size_ChromaKey_ForeColor_BackColor(24, 1, color256_blue, color256_white);    //字體參數(shù)設定(最多256色)
    Show_User_Def_String("自建漢字庫：宋體２４ｘ２４演示", songti24, 24, 2, 50, 100);    //顯示字符串
    Show_User_Def_String("自建漢字庫：楷體２４ｘ２４演示", kaiti24, 24, 2, 50, 125);    //顯示字符串
    Show_User_Def_String("自建漢字庫：黑體２４ｘ２４演示", heiti24, 24, 2, 50, 150);    //顯示字符串

    Font_Size_ChromaKey_ForeColor_BackColor(32, 0, color256_yellow, color256_black);    //字體參數(shù)設定(最多256色)
    Show_User_Def_String("自建漢字庫：宋體３２ｘ３２演示", songti32, 32, 0, 50, 200);    //顯示字符串
    Show_User_Def_String("自建漢字庫：楷體３２ｘ３２演示", kaiti32, 32, 0, 50, 240);    //顯示字符串
    Show_User_Def_String("自建漢字庫：黑體３２ｘ３２演示", heiti32, 32, 0, 50, 280);    //顯示字符串

 // 圖層S0色深恢復初始化狀態(tài)
 #if defined(MCU_8bit_ColorDepth_8bpp)
  BTE_S0_Color_8bpp();
 #endif
 #if defined(MCU_8bit_ColorDepth_16bpp) || defined(MCU_16bit_ColorDepth_16bpp)
  BTE_S0_Color_16bpp();
 #endif
 #if defined(MCU_8bit_ColorDepth_24bpp) || defined(MCU_16bit_ColorDepth_24bpp_Mode_1) || defined(MCU_16bit_ColorDepth_24bpp_Mode_2)
  BTE_S0_Color_24bpp();
 #endif

    BTE_Memory_Copy_Chroma_key(display_address, canvas_image_width, 0, 0, 0, canvas_image_width, 0, 0, 0x01, LCD_width, LCD_height); // 緩存寫好的文字搬移到顯示層,剔除底色0x01
 


上方代碼顯示實例：


RA8889內建128Mb SDRAM作為顯存，顯存是自由定義的，這里我們設定為畫布寬度（canvas_image_width）為800，測試的屏寬（LCD_width）為800，屏高（LCD_height）為480，將顯存規(guī)劃為主顯示層、緩沖層S0、緩沖層S1…如下圖示：



實際操作分為三步：

  1. DMA（線性）：RA8889尋址獲取字符數(shù)據(jù)并通過DMA方式寫入緩存S1；
  2. 轉置：MCU對緩存S1的數(shù)據(jù)轉置后寫入緩存S0，同時給文字加上前景、背景色或者透明色；
  3. BTE剔除底色：RA8889內建BTE功能，可將底色剔除后再復制到主顯示層，因此可以形成文字的透明效果。

附上算法程序供參考：
