好久没发帖了，最近学习了一点HAL库，做了个温度显示的玩意，没啥事了，发个文章记录一下自己的菜。
分以下几步来吧
1.你要有块屏，0.96寸OLED的那种，单色显示
2.你要有个STM32开发板（我用的是STM32L431RCT）
3.顺便找台电脑下载一个STM32CubeIDE
4.简单的找一个OLED的驱动，我是去某宝嫖的，一般卖这个的都有，这个驱动分三个文件，是一个.c和两个.h的，我直接把这三个放在下边
这个是oled.c；基本上都打注释了
/***********************************

uint16_t const displayHeight = 64;

想要显示的汉字和图片都要提前写好字库，但是数字和ASCII码表里的不用写了，里面有。
可能存在的问题：
1.#include "stm32l4xx_hal.h"? ?这个头文件在哪找，我的芯片跟你的不一样，看图（细不细）
2.这三个文件放在哪，来来继续看图
3.文字怎么转成十六进制的那个，软件链接如下
链接：https://pan.baidu.com/s/15GqKJ-zn9kt46JBeMr53ig?
提取码：6666
?4.驱动是有了，怎么用呢，自然是有教程的
首先就是先在主函数里加入头文件
?然后，把屏幕初始化，需要用到OLED_Init()；这个函数，驱动里面有；然后你就可以去让你的屏幕显示去了，例如
?
记得在最后加一个HAL的延时函数，延长个2S
快去试试，然后告诉我怎么样！！！！！！！！
