今天主要对上边的一个模块进行操作,就是这个OLED模块,就是使用I2C驱动0.96’OLED屏幕,因为不习惯用ST的硬件IIC,所以我直接是用了软件模拟IIC配置IIC端口
添加库文件 我们这里直接使用现成的库,因为是模拟IIC,所以只用修改GPIO驱动即可(驱动在**末尾可以下载) 我们需要4个文件oled.c,oled.h,bmp.h,oledfont.h oled.c:IIC驱动,OLED初始化函数以及显示函数 oled.h:GPIO操作的宏定义 bmp.h:图片取的模 oledfont.h:字模 修改GPIO驱动 view plaincopy to clipboardprint?
- #define OLED_SCLK_Clr() HAL_GPIO_WritePin(SCL_GPIO_Port,SCL_Pin,GPIO_PIN_RESET) //SCL
- #define OLED_SCLK_Set() HAL_GPIO_WritePin(SCL_GPIO_Port,SCL_Pin,GPIO_PIN_SET)
- #define OLED_SDIN_Clr() HAL_GPIO_WritePin(SDA_GPIO_Port,SDA_Pin,GPIO_PIN_RESET); //SDA
- #define OLED_SDIN_Set() HAL_GPIO_WritePin(SDA_GPIO_Port,SDA_Pin,GPIO_PIN_SET)
编写函数 首先main函数中以用头文件 view plaincopy to clipboardprint?
- #include "oled.h"
- #include "bmp.h"
然后初始化OLED屏,添加一个变量和一个数组,让OLED显示变量 view plaincopy to clipboardprint?
- OLED_Init();
- uint8_t num = 0;
- uint8_t buf[3];
然后while(1)中编写程序 view plaincopy to clipboardprint?
- num++;
- OLED_Fill(0x00);
- OLED_ShowCHinese(0u,0u,0);
- OLED_ShowCHinese(16u,0u,1);
- OLED_ShowCHinese(32u,0u,2);
- OLED_ShowCHinese(48u,0u,3);
- OLED_ShowCHinese(64u,0u,4);
- OLED_ShowCHinese(80u,0u,5);
- OLED_P8x16Str(16u,2u,(uint8_t *)"EEPW & STM32");
- OLED_P8x16Str(0u,4u,(uint8_t *)"variable:");
- sprintf(buf,"%d",num);
- OLED_P8x16Str(73u,4u,(uint8_t *)buf);
- HAL_Delay(5000);
- OLED_Fill(0x00);
- Draw_BMP(0u,0u,128u,8u,BMP1);
- HAL_Delay(5000);
效果如下
下边写一下如何取字模 首先到网上下载这个软件
下载打开
修改选项
点生成字模,生成的字模复制到oledfont.h中Hzk数组里 view plaincopy to clipboardprint?
- char Hzk[][32]={
- {0x00,0x00,0xF8,0x88,0x88,0x88,0x88,0xFF,0x88,0x88,0x88,0x88,0xF8,0x00,0x00,0x00},
- {0x00,0x00,0x1F,0x08,0x08,0x08,0x08,0x7F,0x88,0x88,0x88,0x88,0x9F,0x80,0xF0,0x00},/*"电",0*/
- /* (16 X 16 , 宋体 )*/
- {0x80,0x82,0x82,0x82,0x82,0x82,0x82,0xE2,0xA2,0x92,0x8A,0x86,0x82,0x80,0x80,0x00},
- {0x00,0x00,0x00,0x00,0x00,0x40,0x80,0x7F,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00},/*"子",1*/

- {0x80,0x60,0x1F,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00},/*"产",2*/

- {0x00,0xFE,0x42,0x42,0x42,0xFE,0x00,0x00,0x00,0xFE,0x42,0x42,0x42,0xFE,0x00,0x00},/*"品",3*/
- /* (16 X 16 , 宋体 )*/
- {0x20,0x20,0x20,0xFE,0x20,0x20,0xFF,0x20,0x20,0x20,0xFF,0x20,0x20,0x20,0x20,0x00},
- {0x00,0x00,0x00,0x7F,0x40,0x40,0x47,0x44,0x44,0x44,0x47,0x40,0x40,0x40,0x00,0x00},/*"世",4*/
- /* (16 X 16 , 宋体 )*/
- {0x00,0x00,0x00,0xFE,0x92,0x92,0x92,0xFE,0x92,0x92,0x92,0xFE,0x00,0x00,0x00,0x00},

- /* (16 X 16 , 宋体 )*/
- };
然后按顺序显示即可 view plaincopy to clipboardprint?
- OLED_ShowCHinese(0u,0u,0);
- OLED_ShowCHinese(16u,0u,1);
- OLED_ShowCHinese(32u,0u,2);
- OLED_ShowCHinese(48u,0u,3);
- OLED_ShowCHinese(64u,0u,4);
- OLED_ShowCHinese(80u,0u,5);
