鸿蒙开发板Hi3861_驱动0.95_oled显示屏ssd1306_code-2.0-CANARY_双显示屏效果
2.0支持windows编译与上传，不需要ubuntu编译
环境搭建需要有耐心：
https://www.cnblogs.com/txwtech/p/15041927.html
首先学会点亮LED的实验
https://www.cnblogs.com/txwtech/p/15139405.html
//驱动oled源代码
源码下载：
https://gitee.com/hihopeorg/harmonyos-ssd1306
下载的源代码有三个文件夹，examples，libm_portm,ssd1306，拷贝到如下目录
F:\code-2.0-canary\applications\sample\wifi-iot\app
参考链接：
https://harmonyos.51cto.com/posts/2126#comment
oled SDA接gpio13
oled SCL接gpio14
VCC --3V3
GND--GND
打开vscode,源码是1.0的，参考如下方法修改：
https://blog.csdn.net/YangHxuan/article/details/119116051
需要修改的几个关键文件：
F:\code-2.0-canary\device\hisilicon\hispark_pegasus\sdk_liteos\build\config
找到usr_config.mk修改
添加：
CONFIG_I2C_SUPPORT=y
ssd1306_demo.c,这个是根据1.0修改为2.0版本的
