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。

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

图片转位图（bmp）格式软件：image2lcd

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_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。

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。
