(HAL库学习8)STM32CubeMX 驱动0.96寸IIC oled(取字模，取图模)

这一篇讲解用STM32CubeMX来使用0.96寸的IIC oled（128*64，VCC,GND,SCL,SDA四脚）

这篇文章我重新写了，如果你是第二次读到这篇文章，对不起，之前卧病额米有讲清楚，只把源码教给大家，没有教大家移植的核心，如何在我们的工程中添加文件我也没有说清楚，我应该照顾所有人的感受，有一些萌新不知道如何移植模块，我应该照顾他们的感受，我会补上一篇专门移植模块的博文，不会移植的去看看。第三，在Cube生成的工程中有一点小地方需要改我忘记说了。对不起。

先给大家看看HAL库驱动的结果

灵魂画师不必在意哈，0.0.

第一步：在CubeMX上开启iic1

第二步：移植我的最下面这三个文件

移植我文章末尾的三个文件，移植方法不会的参考我另外一篇模块移植教程，很简单。这里要先告诉大家，我们使用的是硬件iic驱动的，所以才在Cube中直接开启了IIC1，可以i2c.c中找到I2C_HandleTypeDef hi2c1; 我们就是利用hi2c1对屏幕进行操作的。可以在 oled.c里面找到void WriteCmd(unsigned char I2C_Command)//写命令 void WriteDat(unsigned char I2C_Data)//写数据这两个函数，经常玩大包片机的人肯定懂了，这其实就是核心了，只要写数据的函数移植好了，剩下的都是体力活儿而不是脑力活儿，按照官方的资料网oled写数据就行了。

这里加一步，改一下iic.c

第三步：教大家取字模

用的就是这个烂大街打的取字模软件，你买的oled资料页面下载的资料里面一定有哈，没有就随便找个淘宝卖这个oled的资料页面下载资料，里面一定有，点击上面的选项，跟着上面图片上的设置就可以了，取下来的字模放到你移植好的ascii.h那个文件里面，放到哪里进去一看便知，因为我已经放了一部分了

第四步：教大家取图模

首先这个软件取图模必须是bmp文件哈，而且要黑白二值图像，因为我们的oled就是二值屏幕，想让他五颜六色基本只有梦里能办到哈

按照上面的来即可。

第五步：给大家讲一下都移植好了什么内容

1.输出字符串（两种大小）
2.输出中文（要自己去取字模）还自己写了一个输出中文字符串的函数在oled.c里面
3.输出bmp图像
4.输出数字
5.全屏填充
这些函数的用法自己看oled.c里面讲的很清楚了

下面是那三个文件

这是oled.h
