贡献大家都感兴趣的OLED显示汉字源码 [复制链接]

花了半天时间研究TI的LM3S8962开发板自带OLED显示，在rit128x96x4.c中自己添加了一个RIT128x96x4HZStringDraw函数，实现16*16中文汉字显示，现在汉字存储在内部FLASH中，下一步准备把字库存储到外部FLASH中:D
void RIT128x96x4HZStringDraw(const char *pcStr, unsigned long ulX,
                      unsigned long ulY, unsigned char ucLevel)
{
    unsigned long ulIdx1, ulIdx2, k, hzxx;
    unsigned char ucTemp;
    unsigned short hzTemp;

    g_pucBuffer[0] = 0x15;
    g_pucBuffer[1] = ulX / 2;
    g_pucBuffer[2] = 63;
    RITWriteCommand(g_pucBuffer, 3);
    g_pucBuffer[0] = 0x75;
    g_pucBuffer[1] = ulY;
    g_pucBuffer[2] = ulY + 15;
    RITWriteCommand(g_pucBuffer, 3);
    RITWriteCommand(g_pucRIT128x96x4VerticalInc,
                    sizeof(g_pucRIT128x96x4VerticalInc));

    while(*pcStr != 0)
    {
        ucTemp = *pcStr++;
        if(ucTemp > 0x7f)
        {
            hzTemp = ucTemp;
            hzTemp <<= 8;
            ucTemp = *pcStr++;
            hzTemp |= ucTemp;
            hzxx = findHzIndex(hzTemp);
            k = 7;
            for(ulIdx1 = 0; ulIdx1 < 8; ulIdx1++)
            {
                for(ulIdx2 = 0; ulIdx2 < 16; ulIdx2++)
                {
                    g_pucBuffer[ulIdx2] = 0;
                    if(ulIdx1 < 4)
                    {
                        if(GB_16[hzxx].Msk[ulIdx2*2] & (1 << k))
                        {
                            g_pucBuffer[ulIdx2] = (ucLevel << 4) & 0xf0;
                        }             
                        if(GB_16[hzxx].Msk[ulIdx2*2] & (1 << (k-1)))
                        {
                            g_pucBuffer[ulIdx2] |= (ucLevel) & 0x0f;
                        }           
                    }
                    else
                    {
                        if(GB_16[hzxx].Msk[ulIdx2*2+1] & (1 << k))
                        {
                            g_pucBuffer[ulIdx2] = (ucLevel << 4) & 0xf0;
                        }             
                        if(GB_16[hzxx].Msk[ulIdx2*2+1] & (1 << (k-1)))
                        {
                            g_pucBuffer[ulIdx2] |= (ucLevel) & 0x0f;
                        }           
                    }
                }
                if(k <= 1) k = 7;
                else k-=2;
                RITWriteData(g_pucBuffer, 16);
                ulX += 2;
                if(ulX == 128)
                {
                    return;
                }
            }
        }
        else
        {
            hzxx = (ucTemp-32);
            k = 7;
            for(ulIdx1 = 0; ulIdx1 < 4; ulIdx1++)
            {
                for(ulIdx2 = 0; ulIdx2 < 16; ulIdx2++)
                {
                    g_pucBuffer[ulIdx2] = 0;
                    if(ASCII[hzxx][ulIdx2] & (1 << k))
                    {
                        g_pucBuffer[ulIdx2] = (ucLevel << 4) & 0xf0;
                    }             
                    if(ASCII[hzxx][ulIdx2] & (1 << (k-1)))
                    {
                        g_pucBuffer[ulIdx2] |= (ucLevel) & 0x0f;
                    }           
                }
                if(k <= 1) k = 7;
                else k-=2;
                RITWriteData(g_pucBuffer, 16);
                ulX += 2;
                if(ulX == 128)
                {
                    return;
                }
            }
        }
    }
}

谢谢分享 嘿嘿 赞一个

没有相机用手机照的，不够清晰

求工程？

fengzhang2002

就是这个函数加字库数组就OK了，关注的人多我就发存储外部FLASH的字库工程:D

呵呵 帮顶 需要的朋友快来啊

高，我也正在弄显示，我是在sbc Demo板子上显示汉字，搞了好几天了，就Demo的程序都没搞懂，显示汉字更不用说思路了！！！

:(

高人啊，我这些天一直在弄8962这块板子，常来看你的贴子

好东西 收着了 谢谢楼主

jiao430

我做了个汉字库,放在SST25VF040里面,用LM3S1811.可以显示中英汉字.多国语言也可以做.点阵大小也可以调整.

sptt1

我按照楼主的说法，在rit128x96x4.c里面追加一段，就是楼主写的那段，然后找了个字库，做了个GB_16.c内容相这样
unsigned char GB_16[]={

0x40,0x42,0xDC,0x08,0x00,0x00,0xFE,0x52,
0x92,0x12,0x12,0x92,0x73,0x02,0x00,0x00,
0x40,0x20,0x1F,0x20,0x48,0x46,0x51,0x50,
0x48,0x45,0x42,0x45,0x48,0x50,0x00,0x00,/*"返",2088*/

0x44,0x94,0xA4,0x64,0x04,0x0F,0x04,0xE4,
0x24,0x2C,0x2F,0x24,0xE4,0x04,0x04,0x00,
0x08,0x09,0xF8,0x04,0x03,0x00,0x00,0x3F,
0x40,0x40,0x42,0x46,0x43,0x70,0x00,0x00,/*"范",2089*/
……

可是一编译就出问题

rit128x96x4.c(953): warning:  #223-D: function "findHzIndex" declared implicitly
rit128x96x4.c(962): error:  #154: expression must have struct or union type
rit128x96x4.c(966): error:  #154: expression must have struct or union type

rit128x96x4.c(977): error:  #154: expression must have struct or union type
rit128x96x4.c(1002): error:  #20: identifier "ASCII" is undefined
楼主帮帮忙看看

好东西啊，能分享一下工程吗，刚收到板子，对这个很感兴趣，谢谢
发我邮箱也行dyc12292@163.com

等过两天我用LabVIEW写几个字！~

flyingbing

lz  你哪里有没有tm128160的驱动程序啊  我找不到 又不会自己写

fengzhang2002

汉字数组格式如下：
const FNT_GB16 GB_16[] =
{
"■",
0x00,0x00,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,
0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x7F,0xFC,0x00,0x00,0x00,0x00,
"图",
0x00,0x00,0x7F,0xFC,0x44,0x04,0x47,0xE4,0x44,0x44,0x4A,0x84,0x71,0x04,0x42,0xC4,
0x4C,0x3C,0x71,0x14,0x40,0x84,0x42,0x04,0x41,0x84,0x41,0x04,0x7F,0xFC,0x40,0x04,

多谢多谢

自己顶上去，最近在做基于GRLIB的汉字显示，有需求的朋友可以交流一下

挺清楚的了，不错，顶了！
