=== I2C接口 ===

I2C（Inter－Integrated Circuit）总线是由PHILIPS公司开发的两线式串行总线。I2C 串行总线有两根信号线：一根双向的数据线 SDA；另一根是时钟线 SCL。所有接到 I2C 总线上的设备的串行数据都接到总线的 SDA 线，各设备的时钟线 SCL接到总线的 SCL，每个设备都有唯一的地址。

本讲实际接线采用了[[Microduino-Weather/zh|Microduino Weather]]模块，将OLED转接线直接插在[[Microduino-Weather/zh|Microduino Weather]]模块上即可。

'''  程序说明：'''
 +
*程序实现了两次刷屏和一次图片的循环显示。
 +
*本教程需要使用Wire库，在初始化I2C时不能用Wire.begin()初始化，因为库里默认的SDA和SCL为20和21引脚，需要用Wire.begin(18,19)初始化，或者在Wire.h文件中的引脚定义改为18和19。
 +
*Initial_OLED()为初始化OLED显示屏。
 +
*show1[]数组保存一张图片，在picture_1()调用显示。

目的

了解Microduino OLED，并掌握如何驱动OLED显示屏。

设备

Microduino-Oled是基于SSD1306的0.96吋128x64 OLED显示模块。采用I2C接口，3.3V 电源供电。像素为128*64（128列*64行）。

Microduino-CoreSTM32小巧精悍，其内核来自于ARM公司具有突破性的Cortex-M3内核的32位闪存微控制器。该内核是专门设计于满足集高性能、低功耗、实时应用、具有竞争性价格于一体的嵌入式领域的要求。

Microduino Weather模块集成了三种传感器，分别是光照强度传感器（TSL2561），数字气压传感器（BMP180），数字温湿度传感器（AM2321）。采用I2C接口与核心相连。广泛用于气象监测。

  • 其他硬件设备
  • OLED转接线 一根
  • USB数据线 一根

原理

I2C接口

I2C（Inter－Integrated Circuit）总线是由PHILIPS公司开发的两线式串行总线。I2C 串行总线有两根信号线：一根双向的数据线 SDA；另一根是时钟线 SCL。所有接到 I2C 总线上的设备的串行数据都接到总线的 SDA 线，各设备的时钟线 SCL接到总线的 SCL，每个设备都有唯一的地址。

I2C通讯接法如下：

本讲实际接线采用了Microduino Weather模块，将OLED转接线直接插在Microduino Weather模块上即可。

注意:OLED转接线不要用错。SCL接Microduino-CoreSTM32/zh的SCL，SDA接Microduino-CoreSTM32/zh的SDA,

程序说明：

  • 程序实现了两次刷屏和一次图片的循环显示。
  • 本教程需要使用Wire库，在初始化I2C时不能用Wire.begin()初始化，因为库里默认的SDA和SCL为20和21引脚，需要用Wire.begin(18,19)初始化，或者在Wire.h文件中的引脚定义改为18和19。
  • Initial_OLED()为初始化OLED显示屏。
  • show1[]数组保存一张图片，在picture_1()调用显示。

调试

步骤一：连接好电路。

步骤二：复制程序代码到Maple IDE编译。

步骤三：下载程序代码，观察OLED显示屏的变化。

结果

  • 由上而下依次变白，
文件:Advance9 6.jpg
