STM8驱动SPI接口OLED

2023-10-26 16:38:58

由于中景园电子给出的例程不够全面，因此特地花时间重新整理了一下代码，并加上了其他的功能。本文记录了使用模拟四线 SPI 协议驱动 OLED 的代码。

目录

使用软件：IAR FOR STM8

编程方式：固件库

硬件配套：STM8S105C6T6实验板

字模软件：PCtoLCD2002

2.1 与初始化相关的函数

  OLED_SPI_WriteCmd(0XAE);  // OLED休眠
}

2.3 与显示相关的函数

指定位置刷新显示的功能实现有待进一步研究。

注意：不要频繁调用清屏函数 OLED_Clear()，这会导致屏幕刷新过慢或出现重影现象。

    OLED_GRAM[x][pos] |= temp;
  }
  else 
  {
    OLED_GRAM[x][pos] &= ~temp;
  }
}

  for (x = x1; x <= x2; x++)
  {
     for (y = y1; y <= y2; y++)
     {
        OLED_DrawPoint (x, y, mode);
     }
  }   
  
  OLED_Refresh_Gram();          // 更新显示
}

需要刷新屏幕时，调用：

OLED_Refresh_Gram ();

需要清屏时，调用：

OLED_Clear ();

2.4 显示 ASCII 字符串

/*************************************************************************

      }
      
      temp <<= 1;
      y++;

        x++;
        break;   // 退出循环
      }

    OLED_ShowChar (x, y, *str, size, OLED_ANODE);

}

使用示例：

OLED_ShowString (0, 0, "Welcome To", OLED_FONT_SIZE_16);

2.5 显示中文字符串

注意：传入的参数必须是一个数组的地址，而不是一个中文字符串。这个数组必须存储中文的点阵数据。

    {
      if (temp & 0x80)
      {
        OLED_DrawPoint (x, y, mode);
      }
      else 
      {
        OLED_DrawPoint (x, y, !mode);
      }
      
      temp <<= 1;

        x++;
        break;   // 退出循环
      }

  }
}

    OLED_ShowChar_CH (x, y, str, size, OLED_ANODE);  
    
    x += size / 2;
    str += size;
  }  
}

使用示例：

OLED_ShowChinese (20, 20, &chinese1_1616[0][0], OLED_FONT_SIZE_16, 4);

2.6 显示图片

注意：传入的参数必须是一个数组的地址。这个数组必须存储 BMP 图片的点阵数据。

    return;    

  size = (uint16_t)( height / 8 + ((height % 8)? 1 : 0) ) * width;
  y0 = y;
  
  for (i = 0; i < size; i++)
  {
    temp = *(pic + i);
    
    for (j = 0; j < 8; j++)
    {
      if (temp & 0x80)
      {
        OLED_DrawPoint (x, y, mode);
      }
      else 
      {
        OLED_DrawPoint (x, y, !mode);
      }
      
      temp <<= 1;
      y++;
      
      if (y - y0 == height)
      {
        y = y0;
        x++;
        break;
      }
      
    }
  }
}

使用示例：

OLED_ShowPic (0, 0, &bmp1[0][0], 114, 64, OLED_CATHODE);

2.7 垂直及水平滚动

注意：

  • 这些函数需要在OLED_Refresh_Gram()后调用，且不能放在 while 循环体内。
  • 由于硬件设计原因，OLED 不能直接做到完全垂直滚动，只能做到垂直+水平滚动的效果。完全垂直滚动的实现有待本人进一步研究。
