16*32字体，可以反白显示，在网上查了很多天几乎找不到，对于经验丰富的这些代码很简单，对于新手能想破脑袋，分享的代码属于简化过后的。







显示效果

我把代码放到附件


字符显示代码8x16示例代码有

  2. /***功能描述：显示8x16点阵 ***/
  3. void OLED_Char_8x16(uchar x, uchar y, uchar chr, uchar mode)
  4. {
  5.     unsigned char c = 0, i = 0, j;
  6.     c = chr - ' ';
  7.     if (x > Max_Column - 1)
  8.     {
  9.         x = 0;
  10.         y = y + 2;
  11.     }

  13.     for (j = 0; j < 2; j++)
  14.     {
  15.         OLED_Set_Pos(x, y + j);
  16.         for (i = 0; i < 8; i++)
  17.         {
  18.             if (!mode)
  19.             {
  20.                 OLED_WrDat(F8X16[c * 16 + i + j * 8]);
  21.             }
  22.             else
  23.             {
  24.                 OLED_WrDat(~F8X16[c * 16 + i + j * 8]);
  25.             }
  26.         }
  27.     }
  28. }
  29. /***功能描述：显示16x32点阵 ***/
  30. void OLED_Char_16x32(uchar x, uchar y, uchar chr, uchar mode)
  31. {
  32.     unsigned char c = 0, i = 0, j;
  33.     c = chr - '0';
  34.     if (x > Max_Column - 1)
  35.     {
  36.         x = 0;
  37.         y = y + 2;
  38.     }
  39.     for (j = 0; j < 4; j++) //高度4页
  40.     {
  41.         OLED_Set_Pos(x, y + j);
  42.         for (i = 0; i < 16; i++) //宽度
  43.         {
  44.             if (!mode)
  45.             {
  46.                 OLED_WrDat(F16X32[c * 64 + i + j * 16]);
  47.             }
  48.             else
  49.             {
  50.                 OLED_WrDat(~F16X32[c * 64 + i + j * 16]);
  51.             }
  52.         }
  53.     }
  54. }


  57. /******功能描述：在指定位置显示一个字符,包括部分字符************************
  58. // x:0~127  y:0~7   chr：要显示的字符   size:选择字体大小  mode：1反白,0正常显示

  60. void OLED_ShowChar(uchar x, uchar y, uchar chr, uchar Size, uchar mode)
  61. {
  62.    if (Size == 32)
  63.     {
  64.         OLED_Char_16x32(x, y, chr, mode);
  65.     }
  66.     else if (Size == 16)
  67.     {
  68.         OLED_Char_8x16(x, y, chr, mode);
  69.     }
  70.     else if (Size == 12)
  71.     {

  73.     }
  74. }
