OLED 屏有多种形式，既有单色、双色屏，也有彩色屏；既有I2C接口的，也有SPI接口的。

本次使用的是SPI接口的彩色屏，其分辨率是160*80点像素，16位色彩。

OLED 屏与AC7811的连接关系如下：

SCL ---PA5

SDA ---PA6

RES ---PA7

DC ---PD14

CS ---PD15

BLK ---F12

定义相关引脚输出高低电平的语句为：

#define OLED_SCLK_Clr()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5, GPIO_PIN_RESET) //CLK

#define OLED_SCLK_Set()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5, GPIO_PIN_SET)

#define OLED_SDIN_Clr()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_6, GPIO_PIN_RESET) //DIN

#define OLED_SDIN_Set()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_6, GPIO_PIN_SET)

#define OLED_RST_Clr()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_7, GPIO_PIN_RESET) //RES

#define OLED_RST_Set()HAL_GPIO_WritePin(GPIOA,GPIO_PIN_7, GPIO_PIN_SET)

#define OLED_DC_Clr()HAL_GPIO_WritePin(GPIOD,GPIO_PIN_14, GPIO_PIN_RESET) //DC

#define OLED_DC_Set()HAL_GPIO_WritePin(GPIOD,GPIO_PIN_14, GPIO_PIN_SET)

#define OLED_CS_Clr() HAL_GPIO_WritePin(GPIOD,GPIO_PIN_15, GPIO_PIN_RESET) //CS

#define OLED_CS_Set() HAL_GPIO_WritePin(GPIOD,GPIO_PIN_15, GPIO_PIN_SET)

#define OLED_BLK_Clr() HAL_GPIO_WritePin(GPIOF,GPIO_PIN_12, GPIO_PIN_RESET) //BLK

#define OLED_BLK_Set() HAL_GPIO_WritePin(GPIOF,GPIO_PIN_12, GPIO_PIN_SET)

OLED屏的初始化函数为：
