前言

本文主要讲解hal库配置与0.96寸oled屏的使用。

一、CubeIDE配置OLED显示屏iic引脚

OLED显示屏需要用到iic通信，此处选择了选择pb8为SCL、pb9为SDA

二、OLED驱动库

1.引入库

oled.c代码如下：

#include "oled.h"/根据数据手册可以查到，此数组为命令数据：
0xAE：关闭显示器。
0xD5 0x80：设置显示时钟分频因子/振荡器频率。
0xA8 0x3F：设置多路复用率（1/64）。
0xD3 0x00：设置显示偏移（无偏移）。
0x40：设置起始行为0。
0xA1：设置段重定向（列地址0映射到SEG0）。
0xC8：设置COM扫描方向（上至下）。
0xDA 0x12：设置COM硬件引脚配置。
0x81 0xCF：设置对比度控制。
0xD9 0xF1：设置预充电周期。
0xDB 0x40：设置VCOMH电压倍率。
0xA4：设置显示全部点亮。
0xA6：设置显示正常（非反相）模式。
0x8D 0x14：设置DC-DC电荷泵开启和电荷泵倍率。
0xAF：打开显示器，开始显示。*/
