esp8266_i2c_SH1103_OLED_基于安信可编译器

关于控制芯片SH1106的说明：

12864OLED显示屏是在某宝买的，以下图片是某店铺的说明：


内部电荷泵I2C接口：


SH1106既支持读写访问。R/W位是从地址的一部分。在i2c总线上传输任何数据之前，应该先处理响应的设备。SH1106预留了两个7位从地址(0111100和0111101)。通过将输入SA0连接到逻辑0(VSS)或逻辑1 (VDD1)来设置从地址的最小有效位。i2c总线协议如图7所示。该序列从I2C总线 主设备的开始条件开始，后面跟着从地址。具有相应地址的从设备应答，其他从机将忽略i2c总线传输。在确认之后，会有一个或多个命令来定义被寻址的从机的状态。命令字由一个控制字节组成，它定义了Co和D/C (见note1)，加上一个数据字节(见图7)。最后一个控制字节被标记为一个清除的最重要的位，延续位Co。D /C位的状态定义了数据字节是被解释为命令还是被解释为RAM数据。控制字节和数据字节被总线上相应的从设备接收。在最后一个控制字节之后，根据D /C位设置的不同，数据分为显示数据字节或命令数据字节。如果将D/C位设置为’ 1 ‘，这些显示字节将存储在SRAM中，其地址由数据指针指定。数据指针自动更新，数据被写入到预定的SH1106设备。如果最后一个控制字节的D /C位被设置为’ 0 '，这些命令字节将被解码，设备的设置将根据接收到的命令改变。
每个字节之后的确认只由被寻址的从设备发出。在传输结束时，i2c总线主机发出一个停止条件§。如果R/ W位在从地址中被设置为1，芯片将根据在上次写访问期间发送的D /C位的从地址立即输出数据。如果在一个字节之后没有非应答，从设备停止向主机传送数据。

命令表：
注意：不要使用任何其他命令，否则可能导致系统故障




手册里提供了初始化的演示程序：



以下部分可以参考程序自己写：

这里说一下，我买的模块RST引脚已内置拉高。只有Vcc、Gnd、SDA、SCL这是个引脚。
下面说一下初始化命令的过程：

1.0xae	显示关
2.0x02	设置低列地址
3.0x10	设置高列地址
4.0x40	设置开始显示行
5.0xb0	设置页地址
6.0x81	设置对比度寄存器
0xff	对比度数据（有0~255级对比度）
7.0xa1	设置段重新映射（屏幕左右颠倒））
8.0xa6	设置正常显示
9.0xa8	多路分配模式设置
0x3f	多路复用率数据
10. 0xad	内置升压电荷泵设置
0x8b	开启内置电荷泵（驱动OLED需要比较高的电压，我所买的模块Vpp没接出，所以要开启内置的电荷泵)OLED工作电压源：外部Vpp提供电压6.4v-14.0V;内部Vpp发生器提供电压6.4v-9.0V
0x33	设置Vpp为9v(设置泵电压值Vpp(30H:6.4V；31H:7.4V；32H:8.0V；33H:9.0V)
11.0xc8	设置COM输出扫描方向（屏幕上下颠倒）
12.0xd3	显示偏移模式设置（SH1106仅支持垂直滚动）指定显示开始行到COM0-63之一的映射
0x00	无偏移
13.0xd5	分频比/振荡器频率模式设置(屏幕刷新频率)
0x80	分频比/振荡器频率数据(0x80将时钟设置为100帧/秒)
14.0xd9	无充电/预充电周期模式设置
0x1f	无充电/预充电周期数据
15.0xda	COM引脚硬件配置模式设置,此命令用于设置通用信号垫配置。
0x12	参考文档,顺序:02H,替代:12H)
16.0xdb	取消级别模式设置
0x40	VCOM=0.430VREF:00H, VCOM=0.770VREF:35H,VCOM=1*VREF:40H)
17. 0xaf	显示开

注意:
本人买的的模块RST是内部直接接高电平的，而官方给出的程序是有RST的，所以建议在开显示之前先清屏一下，不然打开就是这个样子。
如果你买的模块是有RST引脚的，就不用清屏，开始先让模块拉低一会就可以了

清屏函数: void i2c_SH1106_CLS(void);

先说下使用这块OLED出现的问题，文档提供的开始显示的列是从0x02开始的，显示也是从0x02开始的，所以写程序的时候开始都是从0x02开始，写 字符串i2c_SH1106_P8x16Str(0, 6,"abcdtfgWTF1234 ")；和画图i2c_SH1106_DrawBMP(0,0,127,7,BMP);显示正常，但写i2c_SH1106_P6x8Str(0, 0,“0123456789”);这种小的字符串是，出现了乱码，把开始的列改成0x01,问题解决，开始显示的也是从第一个像素点开始的。我怀疑是我买的OLED有问题。

在发代码之前先来几张自己弄的XX图片：


这两张图片都是128*64像素的，将格式转成bmp的在取模就行了。
OLED显示的图片:（买的是蓝屏的，效果不够逼真，建议买白屏的）
