我们之后会再写一篇。
现在我们就是用OLED当一个调试的显示屏方便我们调试程序。
为什么要调试呢是为了方便我们看现象从而判断代码的正误。
单片机编程而言经常遇到一个很大的问题就是程序调试。但是单片机不像电脑电脑有很大的屏幕想看什么变量参数直接打印到屏幕就可以了。但是单片机不一样很多时候由于成本和电路结构的限制。它并不会有一个像电脑屏幕那样强大的显示屏这就对我们调试造成了困难
比如让你学习C语言但是不允许使用printf这个打印函数那你想一下C语言是不是根本没法学同样给你一个单片机但是没有任何显示参数的东西那你也没法学单片机。
我们先来看看程序调试有哪些方法 当然串口调试和显示屏调试 也是各有利弊。串口的优势是可以借助强大的电脑电脑端的软件不仅可以显示单独的参数而且可以显示曲线图形图像等。弊端就是需要拖着电脑。而且通常的串口助手只能以信息流的方式呈现数据只能一行一行的打印如果有很多不断变化的数据要显示那就只能在电脑上刷屏显示这样用起来不太方便
显示屏调试的优势是对于不断变化的数据可以覆盖刷新显示。而且显示屏可以始终接在单片机上显示方式很直接。还有我们做一些稍微复杂的东西都会需要一个人机交互界面。这样就可以直接把显示屏当做产品的一部分还是比较好用的。显示屏的弊端就是屏幕太小显示内容有限没有电脑软件强大的功能
所以这两种方法各有各的适用场景需要根据实际情况选择合适的方法。
除了这三种调试方法还有很多种程序的调试方法
OLED介绍 左边四引脚SCL和SDA是I2C的通信引脚需要接到I2C通信引脚上
我下面给的驱动函数模块是GPIO口模拟的I2C通信。所以这两个端口就可以接在任意的GPIO端口上
右边7引脚是SPI通信协议的引脚如果是GPIO口模拟的通信协议就可以接在任意的GPIO端口上
下面看看驱动函数模块有哪些东西吧 根据上述接线图PB6,PB7为0或1因为OLED要接0和1 正好影响到了不过这个也是没关系的我们直接不初始化这两个引脚就行了如果STM32的引脚上电后如果不初始化默认是浮空输入模式。在这个模式下引脚不会输出电平所以不会有什么影响。当然也可以不接上面PB6,7这两个跳线直接PB6输出低电平PB7输出高电平。用GPIO口直接给OLED供电这个也是没有问题的因为OLED功率很小所以可以驱动。但是用GPIO口供电不是很规范。

这里存的是OLED的字库数据因为OLED显示屏是不带字库的想要显示字符图形还要先定义字符的点阵数据下面就是这些字符的点阵数据也就是字库。OLED.c文件会用到这些字库当然这些字库都是不用修改的。
