前言

本篇文章主要介绍OLED的操作和使用。

一、OLED的接线

OLED一共有四根线这里我使用的是IIC的OLED显示屏。

VCC----3.3V或者5V

GND-----GND

SDA-----PB7

SCL-----PB6

二、cubeMX的配置

开启IIC1的IIC功能。基础的配置在这里就不讲了，还不懂的可以看我前面的文章。

OLED cubemx的配置只需要这样设置一下即可。

三、OLED的驱动代码

这里只展示几个比较重要的函数。

oled.c

void OLED_ShowNum(uint8_t x, uint8_t y, unsigned int num, uint8_t len, uint8_t size2)
{
  uint8_t t, temp;
  uint8_t enshow = 0;
  for (t = 0; t < len; t++)
  {
    temp = (num / oled_pow(10, len - t - 1)) % 10;
    if (enshow == 0 && t < (len - 1))
    {
      if (temp == 0)
      {
        OLED_ShowChar(x + (size2 / 2)*t, y, ' ', size2);
        continue;
      }
      else enshow = 1;
    }
    OLED_ShowChar(x + (size2 / 2)*t, y, temp + '0', size2);
  }
}
//在指定位置显示一个字符,包括部分字符
//x:0~127
//y:0~63
//mode:0,反白显示;1,正常显示         
//size:选择字体 16/12 
void OLED_ShowChar(uint8_t x, uint8_t y, uint8_t chr, uint8_t Char_Size)
{
  unsigned char c = 0, i = 0;
  c = chr - ' ';//得到偏移后的值     
  if (x > 128 - 1) { x = 0; y = y + 2; }
  if (Char_Size == 16)
  {
    OLED_Set_Pos(x, y);
    for (i = 0; i < 8; i++)
      OLED_WR_DATA(F8X16[c * 16 + i]);
    OLED_Set_Pos(x, y + 1);
    for (i = 0; i < 8; i++)
      OLED_WR_DATA(F8X16[c * 16 + i + 8]);
  }
  else {
    OLED_Set_Pos(x, y);
    for (i = 0; i < 6; i++)
      OLED_WR_DATA(F6x8[c][i]);
  }
}
//显示一个字符号串
void OLED_ShowString(uint8_t x, uint8_t y, uint8_t *chr, uint8_t Char_Size)
{
  unsigned char j = 0;
  while (chr[j] != '\0')
  {
    OLED_ShowChar(x, y, chr[j], Char_Size);
    x += 8;
    if (x > 120) { x = 0; y += 2; }
    j++;
  }
}
//显示汉字
//hzk 用取模软件得出的数组
void OLED_ShowCHinese(uint8_t x, uint8_t y, uint8_t no)
{
  uint8_t t, adder = 0;
  OLED_Set_Pos(x, y);
  for (t = 0; t < 16; t++)
  {
    OLED_WR_DATA(Hzk[2 * no][t]);
    adder += 1;
  }
  OLED_Set_Pos(x, y + 1);
  for (t = 0; t < 16; t++)
  {
    OLED_WR_DATA(Hzk[2 * no + 1][t]);
    adder += 1;
  }
}

oled.h

void OLED_ShowNum(uint8_t x, uint8_t y, unsigned int num, uint8_t len, uint8_t size2);
void OLED_ShowChar(uint8_t x, uint8_t y, uint8_t chr, uint8_t Char_Size);
void OLED_ShowString(uint8_t x, uint8_t y, uint8_t *chr, uint8_t Char_Size);
void OLED_ShowCHinese(uint8_t x, uint8_t y, uint8_t no);

四、OLED的使用

//第一步初始化OLED
OLED_Init();
//清除屏幕
OLED_Clear();

显示字体数字

OLED规格：128*64

OLED显示字体的原理就是一个个的像素点组成了一个个的字体。

一个中文字体x占16个像素点，英文和符号占8个像素点。

一共可以显示4行一个字体占y的2格

OLED_ShowNum(0,0,20,2,16);
OLED_ShowCHinese(0,0,0);//显示中文，上面的字库中有一个数组，里面包含了字体的编码，这个函数最后的一个参数就是数组的第几个。

中文字体编码的生成

取字模软件：

PCtoLCD2002(用来显示中文)

字模设置成下面这样即可，想要什么字体输入生成就可以了。

总结
