【屏幕驱动移植】点亮OLED屏幕并播放视频

2023-05-16

写在前面

硬件软件准备:

名称	备注
屏幕`SSD1106`	本文章所使用的的屏幕型号，仅仅作为驱动移植示例，其他型号的都可以按照本文的方法推广
树莓派3B	用于驱动屏幕，树莓派2B3B4B等型号都可以
`ESP32`开发板	用于驱动屏幕，具体是ESP32还是ESP32-C3/S2/S3/C6等都可以，树莓派和ESP32选一就可以
VScode	用来写代码，如果路子比较野用txt也可以
`ESP-IDF`	ESP32开发框架，使用的是发行版v5.0，获取方法见官网,如果不用ESP32就不需要
Ubuntu22.04	windows也可以，但是这里以ubuntu系统为例

因为在嵌入式系统中，由于硬件的多样性，移植驱动是常见的事情，本文适合作为驱动移植的小练习。个人认为，驱动移植主要考察读代码和修改代码，说白了就是把别人写好的东西搬运一下，然后将其修改以适应目标平台，使目标平台可以成功运行，就完成了移植的工作。

整体思路：就是我买来了一块屏幕SSD1106,然后一般买一个设备，厂家会提供datasheet，甚至使一些开发文件。如果仅仅有datasheet，要么就自己写驱动，要么就去网上找下载驱动。如果厂家提供了，那么就可以移植。这里厂家是给我提供了驱动资料的，但是我一打开发现只有arduino和STM32的，因此着手准备驱动移植吧。任务目标就是分别使用树莓派和ESP32点亮这块屏幕。

本文的相关代码见我的GitHub：https://github.com/SuperiorLQF/oled_drive

1 原驱动文件

打开厂家提供的驱动例程，在HARDWARE文件夹下的OLED文件夹下，可以看到以下四个C文件
在这里插入图片描述

然后发现核心驱动程序是oled.c和oled.h文件，bmp.h是用来显示特定图片的，而oledfont.h是用来显示

文件内容分别如下，供参考

2 移植方法

我们从这几个文件入手，读懂它们，是移植的关键。

条件编译

首先，我们发现，厂家的.h文件，都是这样的结构:

#ifndef XXX
#define XXX
<程序段1>
...
#else
<程序段2>
...
#endif

这是条件编译，我们知道在嵌入式软开课程中学过，C语言编译包括预处理，编译和链接，我们曾经还学习过用gcc控制只编译不链接等练习。而这里的条件编译就是在预处理过程中，先根据#ifdef XXX判断XXX是否被宏定义过，如果没有，则用#define XXX定义XXX,并且编译接下来的程序段1。否则直接编译程序段2，忽视程序段1.
条件编译的好处是，防止重复编译。例如C包含了头文件A和头文件B，而头文件B又包含了头文件A。这样子头文件A中的东西会被定义两次，在编译时会报重复定义的错误。而如果加入了条件编译，因为在第二次遇到时，#ifndef条件为假，就不会编译相应程序段造成重复定义错误了。

C文件和头文件的关系

习惯上是，将实现相同功能的.c和.h用一样的命名，例如我需要移植的驱动，我就为源文件和头文件分别命名为oleddriver.c和oledfriver.h
其中.c主要是函数实现，.h主要包含函数原型、函数声明、以及一些宏定义。当然，在该.c文件中还要通过#include加入.h，可以简单理解为，#include xxx,h，就是把这个.h的内容cpoy进这个.c文件中，预处理器用头文件内容来代替这句#include。因为.c函数实现不能单独被编译，需要有函数声明，否则会报implicit function define，就是函数没有声明，还有函数中用到的一些宏定义也找不到，因此需要用#include将头文件加入进来，用于链接之前的分别编译。

C语言定义、声明和引用的关系

C语言时从上到下编译顺序执行，按理来说应当先定义再引用，而如果没有先定义就要引用，应该在之前先声明一下，就是告知编译器，我之后会定义的，你可以先用。例子就是C语言函数的定义，如果你定义在main前面，就不需要声明，如果你定义在main后面，就需要声明，#include xxx.h就是这个作用，因为将要引用的函数在其他的.c文件中，编译到引用的地方会发现还没定义，因此先通过添加头文件来实现声明。

具体C语言自己写main文件之外的.c文件和.h文件时，可以参考这个步骤
注意，这种方法时不生成库的，只是把多个c文件编译链接，如果要生成库应该使用CMake中target_link_libraries等命令。

因此，我们只需要删去头文件以及C文件中独立的部分，比如系统头文件，STM32专属的GPIO语句，都可以删去并且寻求目标系统的取代语句。例如树莓派中使用的是wiringPi库中的digitalWrite函数来操作GPIO，使用usleep实现微秒延时。而在ESP32中使用idf提供的driver/gpio库,使用idf自带的freertos函数vTaskdelay实现微秒延时。
当然，我另外把打篮球的视频通过pic2lcd软件生产了C语言数组，然后用python把每一帧的数组拼成二维数组（这一块文件批处理确实挺麻烦的，但我认为不是本次的重点，这里就略过了）
