STM8驱动0.96寸OLED（12864液晶屏）
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。

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。

需要刷新屏幕时，调用：
OLED_Refresh_Gram ();

2.4 显示 ASCII 字符串

break;
default:
return;
}
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) == size)
{
y = y0;
x++;
break; // 退出循环
}
}
}
}
/*************************************************************************

{
x = 0;

x = 0;
y = 0;
OLED_Clear();
}
OLED_ShowChar (x, y, *str, size, OLED_ANODE);
x += size / 2;
str++;
}
}
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。
/*************************************************************************

uint8_t i, j;
uint8_t y0;
uint8_t csize;
y0 = y;
csize = (size / 8 + ((size % 8) ? 1 : 0) ) * (size / 2); //得到字体一个字符对应点阵集所占的字节数
for(i = 0; i < csize; i++)
{
temp = *(str + 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) == size)
{
y = y0;
x++;
break; // 退出循环
}
}
}
}
/*************************************************************************
OLED 打印一行中文字
--------------------------------------------------------------------------
x，y：坐标 *str：中文数组首地址 size：字符大小 num：多少字 mode：阳码/阴码
*************************************************************************/
void OLED_ShowChinese (uint8_t x, uint8_t y, const uint8_t *str, uint8_t size, uint8_t num)
{
uint16_t i;
for (i = 0; i < num * 2; i++)
{
if ( x > (128 - (size / 2)) )
{
x = 0;
y += size;
}
if ( y > (64 - size) )
{
x = 0;
y = 0;
OLED_Clear();
}
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。
/*************************************************************************
OLED 打印 BMP 图片
--------------------------------------------------------------------------
x，y：左上角坐标 *bmp：BMP数组首地址 width，height：图片尺寸大小
*************************************************************************/
void OLED_ShowPic (uint8_t x, uint8_t y, const uint8_t *pic, uint8_t width, uint8_t height, uint8_t mode)
{
uint16_t i, j, size;
uint8_t y0;
uint8_t temp;
if ((x + width > 128) || (y + height > 64))
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。
/*************************************************************************

*************************************************************************/
void OLED_VerHorScroll (enum page_num start_page, enum page_num end_page, enum roll_frame frame, uint8_t scroll_offset, uint8_t dir)
{
OLED_SPI_WriteCmd (0x2E); //关闭滚动

OLED_SPI_WriteCmd (0x00); //虚拟字节（必须加上）
OLED_SPI_WriteCmd (0xFF); //虚拟字节（必须加上）
OLED_SPI_WriteCmd (0x2F); //开启滚动
}
使用示例（要放在 while 外面）：
// 实现图片的垂直+水平滚动
OLED_ShowPic (0, 0, &bmp1[0][0], 114, 64, OLED_CATHODE);
OLED_Refresh_Gram ();
OLED_VerHorScroll (PAGE2, PAGE7, FRAME7, 0, OLED_SCROLL_LEFT);
