STM32+OLED显示屏制作指针式电子钟

一、硬件环境介绍

单片机: STM32F103C8T6

RTC时钟来源: 使用STM32内部RTC定时器得到时间。

显示屏：中景园0.96寸 SPI接口的OLED显示屏

编程软件：keil5

二、实现效果图与代码技术部分介绍

2.1 实现的效果图

2.2 代码技术部分介绍

核心代码内容里分为以下几个部分：

1. RTC时钟代码部分：该电子钟使用的是STM32内部RTC实时时钟，需要编写RTC初始化代码。

2. 电子钟界面逻辑代码部分：电子钟的界面仪表盘画面更新是在RTC秒中断里调用，实现时间指针的更新。

3. OLED驱动代码部分：编写OLED驱动代码，编写常用的OLED接口函数，比如：字符串显示，画点，划线等。

OLED在程序的驱动方式采用显存的方式驱动，定义一个显存数组，程序里的所有逻辑代码先绘制在显存数组里，然后再刷新到OLED显示屏上。
