51单片机模拟iicoled显示

一、IIC协议

（一）概述

IIC（集成电路总线）是由飞利浦公司发明的通讯总线，用于连接微控制器及其外围设备，IIC属于半双工同步通信方式。IIC的数据线只有一根，就是SDA，同一时间不管发送还是接收，只能有一个方向进行操作。

（二）构成

IIC串行总线一般有两根信号线，一根是双向的数据SDA，另一根是时钟线SCL，其中时钟信号是由主控器件产生，所有接到IIC总线设备上的串行数据SDA都接到总线的SDA上，各设备的时钟线SCL接到总线的SCL上，对于并联在一条总线上的每个IC都有唯一的地址。

（三）时序分析

IIC总线在传输数据的过程中一共有三种类型信号，分别为：开始信号、结束信号和应答信号。

1.开始信号

时钟线处于高电平，数据线由高电平转为低电平。

2.结束信号

时钟线处于高电平，数据线由低电平转为高电平。

3.应答信号

发送器每发送一个字节（8个bit），就在时钟脉冲9期间释放数据线，由接收器反馈一个应答信号。应答信号为低电平时，规定为有效应答位（ACK，简称应答位），表示接收器已经成功地接收了该字节；应答信号为高电平时，规定为非应答位（NACK），一般表示接收器接收该字节没有成功。

 （四）代码示例

IIC协议基本函数封装

  1. #include "reg52.h"
  2. #include <intrins.h>
  3.  
  4. sbit scl = P0^1;
  5. sbit sda = P0^3;
  6.  
  7. void IIC_Start()
  8. {
  9. 	sda = 1;
  10. 	scl = 1;
  11. 	_nop_();
  12. 	sda = 0;
  13. }
  14.  
  15. void IIC_Stop()
  16. {
  17. 	sda = 0;
  18. 	scl = 1;
  19. 	_nop_();
  20. 	sda = 1;
  21. 	_nop_();
  22. }
  23.  
  24. char IIC_ACK()
  25. {
  26. 	char flag;
  27. 	
  28. 	sda = 1;//就在时钟脉冲9期间释放数据线
  29. 	_nop_();
  30. 	scl = 1;
  31. 	_nop_();
  32. 	flag = sda;
  33. 	_nop_();
  34. 	scl = 0;
  35. 	_nop_();
  36. 	
  37. 	return flag;
  38. }
  39.  
  40. void IIC_Send_Byte(char dataSend)
  41. {
  42. 	int i;
  43. 	
  44. 	for(i=0;i<8;i++){
  45. 		scl = 0;//scl拉低，让sda做好数据准备
  46. 		sda = dataSend & 0x80;//1000 0000获得dataSend的最高位
  47. 		_nop_();//发送数据建立时间
  48. 		scl = 1;//scl拉高开始发送
  49. 		_nop_();
  50. 		scl = 0;//发送完毕，拉低
  51. 		_nop_();
  52. 		dataSend = dataSend << 1;
  53. 	}
  54. }
  55.  
  56. void main()
  57. {
  58. 	
  59. }

 二、OLED显示

（一）时序分析

写命令/数据编程步骤： 

1. start()

2. 写入 b0111 1000 0x78

3. ACK

4. cotrol byte: (0)(0)000000 写入命令 (0)(1)000000写入数据

5. ACK

6. 写入指令/数据

7. ACK

8. STOP

（二）显示一个点

1、初始化

2、显示位置

    Oled_Write_Cmd(0x20);  //选择一个位置，确认页寻址地址
    Oled_Write_Cmd(0x02);  //选择一个位置，确认页寻址地址
    Oled_Write_Cmd(0xB0);  //选择PAGE0

3、显示内容

    Oled_Write_Data(0x08);  //显示一个点
