    有一点思考,有一点想法,有一点理性

    概述

    某宝上买的OLED,IIC/SPI都可以,买来看的时候发现背面焊的是SPI。板子上又没有硬件SPI,只好用软件模拟SPI。很久之前学的了,现在把它写在CSDN上,各位大佬如有什么想法,欢迎评论!(PS:==文末会附上此工程的全部文件,欢迎下载交流==)

    3.1硬件设计

    硬件方面不多讲,直接看某宝上图片。

    某宝上介绍的比较详细,需要注意的是==这个OLED可以焊接电阻R1~R4中的某几个来选择IIC或者SPI协议==,详情见以下图片 在这里插入图片描述

    3.2软件设计

    3.2.1编程要点

    1、初始化GPIO口来模拟SPI,每个人设置的GPIO口不同,开发板与OLED接线也会不同,所以在拿到别人的程序代码时,==一定要看看ta是用那几个GPIO口来模拟的,不要看ta程序开头的注释,很有可能ta后面把模拟的GPIO口改过,而注释没改==
    2、OLED驱动程序,这里的驱动程序可以参考别人写的,然后自己再加以修改或者补充。
    3、取模,包括文字取模和图片取模。根据自己的需要来取模。需要取模软件的可以私信我。

    3.2.2代码分析

    1、OLED驱动头文件oled.h

    4、主函数

    #include "stm32f4xx.h"
    #include "oled.h"
    #include "bmp.h"
    #include "delay.h"
    void delay(uint32_t count)
    {
      for( ;count!=0;count--);
    }
    int main()
     { //u8 t;
      delay_init();       //延时函数初始化   
       OLED_Init();        //初始化OLED  
       while(1)
      {
       OLED_DrawBMP(0,0,128,8,BMP5);
       delay(0x888888);delay(0x888888);OLED_Clear();   
       
       OLED_DrawBMP(0,0,128,8,BMP6);
       delay(0x888888);delay(0x888888);OLED_Clear();
       
       OLED_DrawBMP(0,0,128,8,BMP7);
       delay(0x888888);delay(0x888888);OLED_Clear();
       
       OLED_DrawBMP(0,0,128,8,BMP8);
       delay(0x888888);delay(0x888888);OLED_Clear();
      } 
    }
    

    主函数说明:该程序显示了四张图片,分别是“鼠” “年” “大” “吉”。今年是鼠年,显示了这四个字,准确的说是四张图片,寓意鼠年能够美好!
    这几个字可以流动显示的,本来准备放视频在上面的,可惜放不了本地视频,我就截图给大家看啦! 如果想看流动效果的可以再b站关注我(b站搜索AXYZdong)查看视频。

    但是这个鼠年从一个蝙蝠说起,在家老老实实码代码吧,233!
