上次在我的树莓派上接入了达特的甲醛传感器，可以把测的甲醛数据上传到服务器上。但是数据还是不够直观，想看数据还得依赖网络、依赖web页面。所以后来买了一块0.9英寸的OLED屏幕，接到了树莓派上，分辨率是128x64，也用了一段时间了，基本满足需求，能够实时显示浓度、时间、网络状态。所以这次分享下用.NET CORE如何驱动一块OLED 屏幕。
准备
- 杜邦线若干
- 一块OLED屏幕，驱动芯片是SSD1306
- 一个开启了GPIO的树莓派，需要支持I2C。如何开启，可参考之前博文。
接线
树莓派的引脚图可以参考之前的博文或者网上自行搜索。
接线比较简单：
- oled的vcc接树莓派的3.3v
- GND 接树莓派的GND
- SCL接树莓派的SCL
- SDA接树莓派的SDA
调试
输入sudo i2cdetect -y 1检查树莓派能否识别到I2C设备，正常的话，会看到如下的结果：
3c就是I2C设备的地址。
然后新建控制台项目，添加nuget包System.Device.Gpio。
写代码来创建I2C设备对象：
_i2c = I2cDevice.Create(new I2cConnectionSettings(1, 0x3c));//创建i2c设备,第一个参数1是busId，
if (_i2c == null)
{
ConsoleHelper.Error("i2c创建失败");
return;
}
I2cConnectionSettings的第一个参数是busId，树莓派3B+就是1。第二个参数是设备的地址，在上面的图中我们看到地址是0x3C
接下来就向I2C设备写数据了，直接调用_i2c.Write(data)方法即可。
SSD1306驱动芯片
简单来说这个芯片是来驱动屏幕，让屏幕显示出各种文字和图案。我们的程序只需要和这个芯片打交道即可，芯片定义了调用_i2c.Write(data)方法时入参data的格式。SSD1306支持的点阵是128x64，即128列，64行。64行有被分成了8份，叫做8个page。每个page在每一列上有8个像素点。所以向芯片写数据时，数据的基本单位就是这8个像素点的数据，xi将这8个像素点的数据绘制到屏幕上。因为SSD1306不带字库，理解芯片的绘制方式对于以后自定义显示文字和图像很重要。
驱动代码如下：
public class SSD1306
{
private I2cDevice _i2c;
