目录
1、简介
本文通过STM32F103C8T6单片机(HAL库)通过软件IIC方式对OLED进行驱动。
2、CubeMX初始化配置
2.1 基础配置
2.1.1 SYS配置
2.1.2 RCC配置
2.2 软件IIC引脚配置
2.3 项目生成
3、KEIL端程序整合
3.1 OLED驱动添加
首先在建立Hardware文件,添加OLED.c如下图所示:
接着对OLED.H进行添加如下图所示:
OLED驱动链接:
OLED https://www.aliyundrive.com/s/BM82mufCiQc 点击链接保存,或者复制本段内容,打开「阿里云盘」APP ,无需下载极速在线查看,视频原画倍速播放。
3.3 主函数代码
首先引用头文件,如下所示:
#include "OLED.h"
接着初始化OLED,如下所示:
OLED_Init(); //初始化OLED
最后进行数据读取打印,如下所示:
OLED_ShowString(1, 1, "1");
main.c如下所示:
