STM32 CubeIDE 控制OLED显示屏

IIC配置：在STM32CubeMX中配置IIC外设为 Fast Mode （400kHz）。

配置IIC引脚

配置RCC（复位与时钟控制）保存并生成HAL库初始化代码。

配置OLED需要的相关代码函数

OLED_Init(); //初始化OLED

OLED_DisPlay_On(); //开启OLED显示

OLED_DisPlay_Off(); //关闭OLED显示

OLED_NewFrame(); //清空显存

OLED_ShowFrame(); //将当前显存显示到屏幕上

OLED_SetPixel(uint8_t x, uint8_t y, OLED_ColorMode color); //设置一个像素点

OLED_DrawLine(uint8_t x1, uint8_t y1, uint8_t x2, uint8_t y2, OLED_ColorMode color);

// 绘制一条线段

OLED_DrawRectangle(uint8_t x, uint8_t y, uint8_t w, uint8_t h, OLED_ColorMode color);

//绘制一个矩形

OLED_DrawFilledRectangle(uint8_t x, uint8_t y, uint8_t w, uint8_t h, OLED_ColorMode color);

//绘制一个填充矩形

OLED_DrawTriangle(uint8_t x1, uint8_t y1, uint8_t x2, uint8_t y2, uint8_t x3, uint8_t y3, OLED_ColorMode color);//绘制一个三角形

OLED_DrawFilledTriangle(uint8_t x1, uint8_t y1, uint8_t x2, uint8_t y2, uint8_t x3, uint8_t y3, OLED_ColorMode color);//绘制一个填充三角形

OLED_DrawCircle(uint8_t x, uint8_t y, uint8_t r, OLED_ColorMode color); //绘制一个圆

OLED_DrawFilledCircle(uint8_t x, uint8_t y, uint8_t r, OLED_ColorMode color); // 绘制一个填充圆

OLED_DrawEllipse(uint8_t x, uint8_t y, uint8_t a, uint8_t b, OLED_ColorMode color);

//绘制一个椭圆

OLED_DrawImage(uint8_t x, uint8_t y, const Image *img, OLED_ColorMode color);

//绘制一张图片

OLED_PrintASCIIChar(uint8_t x, uint8_t y, char ch, const ASCIIFont *font, OLED_ColorMode color); //绘制一个ASCII字符

OLED_PrintASCIIString(uint8_t x, uint8_t y, char *str, const ASCIIFont *font, OLED_ColorMode color); //绘制一个ASCII字符串

OLED_PrintString(uint8_t x, uint8_t y, char *str, const Font *font, OLED_ColorMode color);

//绘制字符串

通过取模助手将需要的图片或文字生成代码保存到font.c font.h

最后在main文件里面调用
