OLED SSD1306 4PIN简介

SSD1306是一款带控制器的用于OLED点阵图形显示系统的单片CMOS OLED/PLED驱动器。它由128个SEG（列输出）和64个COM（行输出）组成。该芯片专为共阴极OLED面板设计。

SSD1306内置对比度控制器、显示RAM（GDDRAM）和振荡器，以此减少了外部元件的数量和功耗。该芯片有256级亮度控制。数据或命令由通用微控制器通过硬件选择的6800/8000系通用并行接口、I2C接口或==SPI（串行外围接口）==发送。该芯片适用于许多小型便携式应用，如手机副显示屏、MP3播放器和计算器等。

内部结构见下图：

利用Arduino IDE对STM32和OLED进行编程

根据原理图，STM32和OLED的引脚接线应为：3.3V接VCC，GND接GND，PB6接SCL，PB7接SDA。

OLED的图形显示利用u8g2库，这个库在Arduino IDE里也有移植，需要第三方下载。

下面提供一个示例：
