标题: stc8H1K08单片机驱动i2C接口的0.91吋OLED源程序 附stc8H.h头文件
STC8H1K08可以替代过去的STC15W408as，但需要对程序进行必要的修改。大致需要注意以下三点：
1、使用STC官方提供的STC8Hxx系列头文件替代stc15.h；
2、使用IO口时需要事先进行设置；
3、需要注意延时函数的修改。
本人在将STC15W408as驱动i2c接口OLED的程序，移植用于STC8H1K08时多次没有通过，后来下载时将程序运行IRC频率降至5.5MHz时才通过，判断应该适当增加延时。在原来的void i2c_Start()、void i2c_Stop()和void Write_i2c_Byte(unsigned char i2c_Byte)增加了最短的延时，最后IRC频率在5.5~35MHz下均可正常运行。所有程序代码附在stc8h_oled.rar中。包含stc8H.h头文件

单片机源程序如下:
  1. #include "stc8H.h"

  3. sbit SCL=P3^6;
  4. sbit SDA=P3^7;

  6. void delay()
  7. {
  8.         char i;
  9.         for(i=0;i<1;i++);
  10. }

  12. void delay_us(char us)
  13. {
  14.         char i;
  15.         for(i=0;i<us;i++);
  16. }

  18. void delay_ms(int ms)
  19. {
  20.         int i,j,n;
  21.         //n=1100; //11.0592MHz
  22.         //n=2200; //24MHz
  23.         n=3300; //35MHz
  24.         for(j=0;j<ms;j++)
  25.         {
  26.                 for(i=0;i<n;i++);
  27.         }
  28. }

后来下载时将程序运行IRC频率降至5.5MHz时才通过
===说明程序不完善，还是要学习STC完善的老刘爱捣鼓示波器的 I2C-OLED12864, SPI-OLED12864演示程序
