测试工程下载 OLED驱动原理—IIC通信
这里是基础原理可以大致浏览即可有个基本印象
下图为 0.96寸单色OLED他们有四个针脚VCC GND SCK SDA 前俩个就是供电的后俩个是IIC通信接口与单片机通信。 SSD1306 单色 0.96 OLED 显示屏特性 OLED显示屏可以从最大160度的各个角度观看。该显示器支持 3v 和 5v 电源这使得它可以与 3.3V 和 5V 逻辑一起工作。SSD1306驱动程序及其库使OLED可以通过简单的命令显示字符和位图。不同颜色的 OLED 也可供选择甚至不同尺寸也可供选择。与 LCD 相比OLED 显示屏尺寸更小显示效果更好 0.96 寸OLED显示屏所用的驱动IC为SSD1306 其具有内部升压功能所以在设计的时候不需要再专一设计升压电路 当然了本屏也可以选用外部升压。 SSD1306的每页包含了128个字节总共8页这样刚好是 128*64 的点阵大小。 由上图可知0.96寸OLED有八页128列每一页又有8小行
对于一个0.96寸OLED有8页也可以称为8个水平扫描线和128列。通过8页和128列可以操作所有64x128个像素点。
第一步是控制页数
OLED屏幕的每一页都是由一组水平扫描线构成的每次只能显示一页。通过控制页数的切换我们可以在屏幕上显示不同的内容。总共有8页可以通过指令来切换到目标页。
第二步是控制列数
在每一页上OLED屏幕有128列。列数确定了水平方向的像素点位置。我们可以通过指令来选择在特定页上的目标列。
这样我们可以通过控制页数和列数的组合来操作到所有64x128个像素点。可以根据需要在特定的页和列上显示图形、文字或其他内容。 程序理解与设计 1.操作时序—写命令、写数据 由上图可知在通过IIC尝试控制OLED时有俩个主要的操作1.写数据0x40 2.写命令0x00 因此写指令与写数据的操作过程完全一致只是写入指令与数据的寄存器不同一个是0x00,一个是0x40选择好了写入的寄存器是指令还是数据后就能传递我们具体的指令或者数据了
/**********************************************
// IIC Write Command
**********************************************/
void Write_IIC_Command(unsigned char IIC_Command)
{IIC_Start();Write_IIC_Byte(0x78); //Slave address,SA00IIC_Wait_Ack(); Write_IIC_Byte(0x00); //write commandIIC_Wait_Ack(); Write_IIC_Byte(IIC_Command); IIC_Wait_Ack(); IIC_Stop();
}
/**********************************************
// IIC Write Data
**********************************************/
void Write_IIC_Data(unsigned char IIC_Data)
{IIC_Start();Write_IIC_Byte(0x78); //D/C#0; R/W#0IIC_Wait_Ack(); Write_IIC_Byte(0x40); //write dataIIC_Wait_Ack(); Write_IIC_Byte(IIC_Data);IIC_Wait_Ack(); IIC_Stop();
} 二、清屏命令
接下来讲解一下清屏命令从这个命令我们可以初步明白一下写命令与写数据具体代表什么以及8页128列究竟是怎么操作的
首先是整了一个写入函数这个函数没有别的意思就是整合了Write_IIC_Command与Write_IIC_Data(起到了有命令写命令有数据写数据的效果主要是方便后续程序编写不管写数据还是命令直接调用它就行了。
它有俩个参数第一个参数dat是数据第二个参数cmd就是选择这个dat数据是写入命令寄存器的还是写入数据寄存器的。
期间还写了俩个宏定义用来提醒自己这里的步骤是写命令寄存器的还是写数据寄存器的
#define OLED_CMD 0 //写命令
#define OLED_DATA 1 //写数据void OLED_WR_Byte(unsigned dat,unsigned cmd)
{if(cmd){ Write_IIC_Data(dat);}else { Write_IIC_Command(dat);}
}
//清屏函数,清完屏,整个屏幕是黑色的!和没点亮一样!!!
void OLED_Clear(void)
{ u8 i,n; for(i0;i8;i) { OLED_WR_Byte (0xb0i,OLED_CMD); //设置页地址0~7OLED_WR_Byte (0x00,OLED_CMD); //设置显示位置—列低地址OLED_WR_Byte (0x10,OLED_CMD); //设置显示位置—列高地址 for(n0;n128;n)OLED_WR_Byte(0,OLED_DATA); } //更新显示
}
我们可以看到整个函数一进入就是进行一个8次的循环每次循环进入
首先就会先选择哪一页需要清空而OLED共有八页因此需要循环八次来选择0~7这八个页号~
其次选择哪一列需要清空因为这是个屏幕我们使用平面直角坐标系里确定一个点来理解如果OLED是横向显示的前面的页就好比确定了Y坐标这里的列就是确定了X坐标这样先确定了Y再内套一个循环128次依次选择一列上的X进行清空。
综上这个函数总共是8*128个循环操作才使得OLED全部清空~~~ 三、初始化SSD1306显示
这部分初始化分为单片机IIC引脚的初始化、以及对SSD1306写入一些必要命令的初始化
在 单片机IIC引脚的初始化 方面不多说而对SSD1306写入一些必要命令方面我们可以通过我的注释看出有对比度、反显等可以设置具体写入什么进行设置可以百度我这配的都是正常的通用设置这种写命令一般都是先写寄存器在写数据设置
//初始化SSD1306
void OLED_Init(void)
{ GPIO_InitTypeDef GPIO_InitStructure; //定义初始化结构体RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE); //使能APB2端口时钟GPIO_InitStructure.GPIO_Pin GPIO_Pin_6|GPIO_Pin_7; //初始化B6,B7GPIO_InitStructure.GPIO_Mode GPIO_Mode_Out_PP; //推挽输出GPIO_InitStructure.GPIO_Speed GPIO_Speed_50MHz; //速度50MHzGPIO_Init(GPIOB, GPIO_InitStructure); //初始化GPIOBGPIO_SetBits(GPIOB,GPIO_Pin_6|GPIO_Pin_7); delay_ms(100); OLED_WR_Byte(0xAE,OLED_CMD);//--display off 关闭显示屏OLED_WR_Byte(0x00,OLED_CMD);//---set low column address 设置低列地址 OLED_WR_Byte(0x10,OLED_CMD);//---set high column address 设置高列地址OLED_WR_Byte(0x40,OLED_CMD);//--set start line address 设置起始行地址OLED_WR_Byte(0xB0,OLED_CMD);//--set page address 设置页地址OLED_WR_Byte(0x81,OLED_CMD); // contract control 设置对比度控制OLED_WR_Byte(0xFF,OLED_CMD);//--128 对比度值设置为128OLED_WR_Byte(0xA1,OLED_CMD);//set segment remap 设置段重映射OLED_WR_Byte(0xA6,OLED_CMD);//--normal / reverse 设置正常显示/反向显示OLED_WR_Byte(0xA8,OLED_CMD);//--set multiplex ratio(1 to 64) 设置多路复用比率1到64OLED_WR_Byte(0x3F,OLED_CMD);//--1/32 duty 设置Duty值为1/32OLED_WR_Byte(0xC8,OLED_CMD);//Com scan direction 设置COM扫描方向OLED_WR_Byte(0xD3,OLED_CMD);//-set display offset 设置显示偏移OLED_WR_Byte(0x00,OLED_CMD);// 设置显示起始行OLED_WR_Byte(0xD5,OLED_CMD);//set osc division 设置振荡器分频OLED_WR_Byte(0x80,OLED_CMD);// 设置振荡器分频值为80OLED_WR_Byte(0xD8,OLED_CMD);//set area color mode off 设置区域颜色模式关闭OLED_WR_Byte(0x05,OLED_CMD);// 设置区域颜色模式值为05OLED_WR_Byte(0xD9,OLED_CMD);//Set Pre-Charge Period 设置预充电周期OLED_WR_Byte(0xF1,OLED_CMD);// 设置预充电周期值为F1OLED_WR_Byte(0xDA,OLED_CMD);//set com pin configuartion 设置COM引脚配置OLED_WR_Byte(0x12,OLED_CMD);// 设置COM引脚配置值为12OLED_WR_Byte(0xDB,OLED_CMD);//set Vcomh 设置VcomhOLED_WR_Byte(0x30,OLED_CMD);// 设置Vcomh值为30OLED_WR_Byte(0x8D,OLED_CMD);//set charge pump enable 设置充电泵使能OLED_WR_Byte(0x14,OLED_CMD);// 设置充电泵使能值为14OLED_WR_Byte(0xAF,OLED_CMD);//--turn on oled panel 打开显示屏
} 四、开启与关闭指令
这是OLED开启与关闭的函数主要原理也是向它的寄存器写数据命令可以快捷开启关闭OLED一般程序初始化时会关闭OLED防止乱显示初始化完成后打开即可
有时开机刷新比较慢像素可能会一行一行刷出来这时可以先调用 OLED_Display_Off在紧接着调用刷新显示的函数然后在调用OLED_Display_On像素就不会一行一行刷出来了~~原理就是等他刷新显示的函数循环加载完成了再整个打开OLED
//开启OLED显示
void OLED_Display_On(void)
{OLED_WR_Byte(0X8D,OLED_CMD); //SET DCDC命令OLED_WR_Byte(0X14,OLED_CMD); //DCDC ONOLED_WR_Byte(0XAF,OLED_CMD); //DISPLAY ON
}
//关闭OLED显示
void OLED_Display_Off(void)
{OLED_WR_Byte(0X8D,OLED_CMD); //SET DCDC命令OLED_WR_Byte(0X10,OLED_CMD); //DCDC OFFOLED_WR_Byte(0XAE,OLED_CMD); //DISPLAY OFF
} 五、OLED坐标设置
这是设置OLED显示绘制起点的函数每种文字图像都有占用的范围比如宋体汉字每个字一般占用16*16像素,而字母可以占用更少的像素区域~~
//坐标设置
void OLED_Set_Pos(unsigned char x, unsigned char y)
{ OLED_WR_Byte(0xb0y,OLED_CMD);OLED_WR_Byte(((x0xf0)4)|0x10,OLED_CMD);OLED_WR_Byte((x0x0f),OLED_CMD);
} 如图可以更直观理解一个中文字是怎么点亮的小框代表一个中文字需要占用的像素区大框就是OLED全部显示区Y坐标代表页X坐标代表列。 六、常用ASCLL码字符字库 这是常用ASCLL码字符字库分俩种大小12*6以及16*8的字母这个直接复制使用即可
//常用ASCII表
//偏移量32
//ASCII字符集
//偏移量32
//大小:12*6

七、字符显示函数 这是在指定位置显示一个字符的函数X,Y是它的起始区域chr就是该字符的ASCLL码Size是选择它的显示占用像素点16*8还是12*6本质上是引用六中的常用字库
//在指定位置显示一个字符,包括部分字符
//x:0~127
//y:0~63
//mode:0,反白显示;1,正常显示
//size:选择字体 16/12
void OLED_ShowChar(u8 x,u8 y,u8 chr,u8 Char_Size)
{ unsigned char c0,i0; cchr- ;//得到偏移后的值 if(xMax_Column-1){x0;yy2;}if(Char_Size 16){OLED_Set_Pos(x,y); for(i0;i8;i)OLED_WR_Byte(F8X16[c*16i],OLED_DATA);OLED_Set_Pos(x,y1);for(i0;i8;i)OLED_WR_Byte(F8X16[c*16i8],OLED_DATA);}else { OLED_Set_Pos(x,y);for(i0;i6;i)OLED_WR_Byte(F6x8[c][i],OLED_DATA);}
} 程序设计 在坐标0,0处打印一个大写的A16*8像素 在坐标12,0处打印一个小写的b12*6像素 并全屏闪烁每0.5秒。 主函数代码
之前 其余函数代码都一个个讲了因此这里只贴出主函数代码
