一、OLED
OLED使用四针的小屏幕，VCC、GND、SCL、SDA
关于OLED的代码网上有很多，随便找就行，具体的对应管脚自己修改
目前使用的管脚如下：
VCC ------VDD
GND------GND
SCL-------PA3
SDA------ PF5
这里不能使用原理图，不知道什么原因，一添加就说有敏感词，不能发表。原理图就不放了
（原因：不能复制粘贴，徐上传图片）

二、代码
1、在OLED初始化中配置SCL、SDA对应管脚代码

void OLED_Init(void)
{
    GPIO_Config_T gpioConfig;
    RCM_EnableAHBPeriphClock(RCM_AHB_PERIPH_GPIOA);
    /* SCL GPIO configuration */
    gpioConfig.pin = GPIO_PIN_3;
    gpioConfig.mode = GPIO_MODE_OUT;
    gpioConfig.outtype = GPIO_OUT_TYPE_OD;
    gpioConfig.speed = GPIO_SPEED_50MHz;
    gpioConfig.pupd = GPIO_PUPD_NO;
    GPIO_Config(GPIOA, &gpioConfig);   

     RCM_EnableAHBPeriphClock(RCM_AHB_PERIPH_GPIOF);
    /* SDA GPIO configuration */
    gpioConfig.pin = GPIO_PIN_5;
    GPIO_Config(GPIOF, &gpioConfig);

         OLED_WR_Byte(0xAE,OLED_CMD);
OLED_WR_Byte(0x00,OLED_CMD);
OLED_WR_Byte(0x10,OLED_CMD);
OLED_WR_Byte(0x40,OLED_CMD);
OLED_WR_Byte(0x81,OLED_CMD);
OLED_WR_Byte(0xCF,OLED_CMD);
OLED_WR_Byte(0xA1,OLED_CMD);
OLED_WR_Byte(0xC8,OLED_CMD);
OLED_WR_Byte(0xA6,OLED_CMD);
OLED_WR_Byte(0xA8,OLED_CMD);
OLED_WR_Byte(0x3f,OLED_CMD);
OLED_WR_Byte(0xD3,OLED_CMD);
OLED_WR_Byte(0x00,OLED_CMD);
OLED_WR_Byte(0xd5,OLED_CMD);
OLED_WR_Byte(0x80,OLED_CMD);
OLED_WR_Byte(0xD9,OLED_CMD);
OLED_WR_Byte(0xF1,OLED_CMD);
OLED_WR_Byte(0xDA,OLED_CMD);
OLED_WR_Byte(0x12,OLED_CMD);
OLED_WR_Byte(0xDB,OLED_CMD);
OLED_WR_Byte(0x40,OLED_CMD);
OLED_WR_Byte(0x20,OLED_CMD);
OLED_WR_Byte(0x02,OLED_CMD);
OLED_WR_Byte(0x8D,OLED_CMD);
OLED_WR_Byte(0x14,OLED_CMD);
OLED_WR_Byte(0xA4,OLED_CMD);
OLED_WR_Byte(0xA6,OLED_CMD);
OLED_Clear();
OLED_WR_Byte(0xAF,OLED_CMD);
}
2、OLED文件添加
网上找到OLED文件，然后添加在自己的文件夹里面，然后再keil目录里面添加文件
这里也一样的，图片就不放了

file:///C:/Users/JHC/AppData/Local/Temp/ksohtml10048/wps6.jpg
3、添加屏幕显示代码文件bmp.h
#ifndef __BMP_H
#define __BMP_H
unsigned char BMP2[] =
{

话说，为什么要选择这两个引脚。
使用GPIO来模拟时序，应该是任意一个GPIO都可以啊
