【RT1052】基于SPI接口的OLED屏显示

jinglixixi

    前面介绍了I2C接口OLED屏的使用方法，这里再介绍一下SPI接口的OLED屏用法,当然使用的还是键盘端口（KPP）。

    OLED屏与RT1052的连接关系如下：

    CS  --P1.24

    DC  --P1.26

    RST --P1.28

    DIN --P1.27  D1   

    SCLK--P1.25  D0

    使个引脚输出高低电平的定义如下：

#define OLED_CS_Clr()       GPIO_PinWrite(GPIO1, (24U), 0U);

#define OLED_CS_Set()       GPIO_PinWrite(GPIO1, (24U), 1U);

#define OLED_DC_Clr()       GPIO_PinWrite(GPIO1, (26U), 0U);

#define OLED_DC_Set()       GPIO_PinWrite(GPIO1, (26U), 1U);

#define OLED_RST_Clr()     GPIO_PinWrite(GPIO1, (28U), 0U);

#define OLED_RST_Set()      GPIO_PinWrite(GPIO1, (28U), 1U);

#define OLED_SDIN_Clr()    GPIO_PinWrite(GPIO1, (27U), 0U);

#define OLED_SDIN_Set()     GPIO_PinWrite(GPIO1, (27U), 1U);

#define OLED_SCLK_Clr()    GPIO_PinWrite(GPIO1, (25U), 0U);

#define OLED_SCLK_Set()     GPIO_PinWrite(GPIO1, (25U), 1U);

    配置各引脚为输出端口的函数为：

void LCD_GPIO_Cogfig(void)

{

    gpio_pin_config_t led_config ={kGPIO_DigitalOutput, 0, kGPIO_NoIntmode};

    GPIO_PinInit(GPIO1, (25U),&led_config);

    GPIO_PinInit(GPIO1, (27U),&led_config);

    GPIO_PinInit(GPIO1, (24U),&led_config);

    GPIO_PinInit(GPIO1, (26U),&led_config);

    GPIO_PinInit(GPIO1, (28U),&led_config);

    GPIO_PinInit(GPIO1, (30U),&led_config);

    GPIO_PinInit(GPIO1, (31U),&led_config);

}

该OLED屏的初始化函数为：

void OLED_Init(void)

{

    LCD_GPIO_Cogfig();

    OLED_RST_Set();

    delay_ms(100);

    OLED_RST_Clr();

    delay_ms(100);

    OLED_RST_Set();

    OLED_WR_Byte(0xAE,OLED_CMD);//--turnoff oled panel

    OLED_WR_Byte(0x00,OLED_CMD);//---setlow column address

    OLED_WR_Byte(0x10,OLED_CMD);//---sethigh column address

    OLED_WR_Byte(0x40,OLED_CMD);//--setstart line address  Set Mapping RAM   

    OLED_WR_Byte(0x81,OLED_CMD);//--set contrastcontrol register

    OLED_WR_Byte(0xCF,OLED_CMD); //Set SEG Output Current Brightness

    OLED_WR_Byte(0xA1,OLED_CMD);//--SetSEG/Column Mapping

    OLED_WR_Byte(0xC8,OLED_CMD);//SetCOM/Row Scan Direction

    OLED_WR_Byte(0xA6,OLED_CMD);//--setnormal display

    OLED_WR_Byte(0xA8,OLED_CMD);//--setmultiplex ratio(1 to 64)

    OLED_WR_Byte(0x3f,OLED_CMD);//--1/64duty

    OLED_WR_Byte(0xD3,OLED_CMD);//-setdisplay offset

    OLED_WR_Byte(0x00,OLED_CMD);//-notoffset

    OLED_WR_Byte(0xd5,OLED_CMD);//--setdisplay clock divide ratio/oscillator frequency

    OLED_WR_Byte(0x80,OLED_CMD);//--setdivide ratio, Set Clock as 100 Frames/Sec

    OLED_WR_Byte(0xD9,OLED_CMD);//--setpre-charge period

    OLED_WR_Byte(0xF1,OLED_CMD);//SetPre-Charge as 15 Clocks & Discharge as 1 Clock

    OLED_WR_Byte(0xDA,OLED_CMD);//--setcom pins hardware configuration

    OLED_WR_Byte(0x12,OLED_CMD);

    OLED_WR_Byte(0xDB,OLED_CMD);//--setvcomh

    OLED_WR_Byte(0x40,OLED_CMD);//SetVCOM Deselect Level

    OLED_WR_Byte(0x20,OLED_CMD);//-SetPage Addressing Mode (0x00/0x01/0x02)

    OLED_WR_Byte(0x02,OLED_CMD);//

    OLED_WR_Byte(0x8D,OLED_CMD);//--setCharge Pump enable/disable

    OLED_WR_Byte(0x14,OLED_CMD);//--set(0x10)disable

    OLED_WR_Byte(0xA4,OLED_CMD);//Disable Entire Display On (0xa4/0xa5)

    OLED_WR_Byte(0xA6,OLED_CMD);//Disable Inverse Display On (0xa6/a7)

    OLED_WR_Byte(0xAF,OLED_CMD);//--turnon oled panel

    OLED_WR_Byte(0xAF,OLED_CMD);/*display ON*/

    OLED_Clear();

    OLED_Set_Pos(0,0);  

}

SPI 接口OLED屏显示效果

实现图示效果的主程序为：

int main(void)

{

    uint16_t i=0;

    gpio_pin_config_t led_config ={kGPIO_DigitalOutput, 0, kGPIO_NoIntmode};

    BOARD_ConfigMPU();

    BOARD_InitPins();

    BOARD_BootClockRUN();

    BOARD_InitDebugConsole();

    GPIO_PinInit(EXAMPLE_LED_GPIO,EXAMPLE_LED_GPIO_PIN, &led_config);

    delay();

    OLED_Init();

    OLED_Clear();

    OLED_ShowString(8,0,"OK1052-C");

    OLED_ShowString(8,2,"OLEDTEST");

    OLED_ShowString(8,4,"JINGLIXIXI");  

    OLED_ShowString(8,6,"2018/11/8");

    while(1);

}
