【ACM32G103RCT6】spi驱动SH1106OLED [复制链接]

最新入手一个1.3寸sh1106的OLED屏，spi接口，这样显示速度相比IIC就会高很多。

【移植】

1、拷贝官方的驱动例程到工程，并把他添加进工程中。

2、选择驱动IO，定义端口与PIN如下：

#define OLED_PORT   GPIOA
#define OLED_SCL_PIN  GPIO_PIN_5
#define OLED_SDA_PIN  GPIO_PIN_7
#define OLED_RES_PIN  GPIO_PIN_2
#define OLED_DC_PIN   GPIO_PIN_3
#define OLED_CS_PIN   GPIO_PIN_4

3、修改SLC与SDA、RES、DC、CS的高平电平：


#define OLED_SCL_Clr()   OLED_PORT->BSC = OLED_SCL_PIN << 16U //SCL
#define OLED_SCL_Set()   OLED_PORT->BSC = OLED_SCL_PIN  

#define OLED_SDA_Clr() OLED_PORT->BSC = OLED_SDA_PIN << 16U //SDA
#define OLED_SDA_Set() OLED_PORT->BSC = OLED_SDA_PIN

#define OLED_RES_Clr() OLED_PORT->BSC = OLED_RES_PIN << 16U //RES
#define OLED_RES_Set() OLED_PORT->BSC = OLED_RES_PIN

#define OLED_DC_Clr()  OLED_PORT->BSC = OLED_DC_PIN << 16U //DC
#define OLED_DC_Set()  OLED_PORT->BSC = OLED_DC_PIN

#define OLED_CS_Clr()  OLED_PORT->BSC = OLED_CS_PIN << 16U  //CS
#define OLED_CS_Set()  OLED_PORT->BSC = OLED_CS_PIN

4、修改OLED—INIT如下：

//OLED的初始化
void OLED_Init(void)
{
	GPIO_InitTypeDef  GPIO_InitStruct;

	__HAL_RCC_GPIOA_CLK_ENABLE();
	
	  GPIO_InitStruct.Pin       = OLED_SCL_PIN | OLED_SDA_PIN | OLED_RES_PIN | OLED_DC_PIN | OLED_CS_PIN ;
    GPIO_InitStruct.Mode      = GPIO_MODE_OUTPUT_PP;
    GPIO_InitStruct.Pull      = GPIO_PULLUP;
    GPIO_InitStruct.Drive     = GPIO_DRIVE_LEVEL3;
    GPIO_InitStruct.Alternate = GPIO_FUNCTION_0;

    HAL_GPIO_Init(OLED_PORT, &GPIO_InitStruct);

	OLED_RES_Clr();
	HAL_Delay(200);
	OLED_RES_Set();
	
	OLED_WR_Byte(0xAE,OLED_CMD); /*display off*/ 
	OLED_WR_Byte(0x02,OLED_CMD); /*set lower column address*/ 
	OLED_WR_Byte(0x10,OLED_CMD); /*set higher column address*/ 
	OLED_WR_Byte(0x40,OLED_CMD); /*set display start line*/ 
	OLED_WR_Byte(0xB0,OLED_CMD); /*set page address*/
	OLED_WR_Byte(0x81,OLED_CMD); /*contract control*/ 
	OLED_WR_Byte(0xcf,OLED_CMD); /*128*/ 
	OLED_WR_Byte(0xA1,OLED_CMD); /*set segment remap*/ 
	OLED_WR_Byte(0xA6,OLED_CMD); /*normal / reverse*/ 
	OLED_WR_Byte(0xA8,OLED_CMD); /*multiplex ratio*/ 
	OLED_WR_Byte(0x3F,OLED_CMD); /*duty = 1/64*/ 
	OLED_WR_Byte(0xad,OLED_CMD); /*set charge pump enable*/ 
	OLED_WR_Byte(0x8b,OLED_CMD); /* 0x8B 内供 VCC */ 
	OLED_WR_Byte(0x33,OLED_CMD); /*0X30---0X33 set VPP 9V */ 
	OLED_WR_Byte(0xC8,OLED_CMD); /*Com scan direction*/ 
	OLED_WR_Byte(0xD3,OLED_CMD); /*set display offset*/ 
	OLED_WR_Byte(0x00,OLED_CMD); /* 0x20 */ 
	OLED_WR_Byte(0xD5,OLED_CMD); /*set osc division*/ 
	OLED_WR_Byte(0x80,OLED_CMD); 
	OLED_WR_Byte(0xD9,OLED_CMD); /*set pre-charge period*/ 
	OLED_WR_Byte(0x1f,OLED_CMD); /*0x22*/ 
	OLED_WR_Byte(0xDA,OLED_CMD); /*set COM pins*/ 
	OLED_WR_Byte(0x12,OLED_CMD); 
	OLED_WR_Byte(0xdb,OLED_CMD); /*set vcomh*/ 
	OLED_WR_Byte(0x40,OLED_CMD);
	OLED_Clear();
	OLED_WR_Byte(0xAF,OLED_CMD); /*display ON*/
}

到此移植驱动结束。

对的，看能不能做个曲线，没得经验，大佬带我
