鸿蒙硬件HI3861-OLED扫雷版本

使用HI3861实现在OLED1602上面实现扫雷

效果请看：https://www.bilibili.com/video/BV1U54y1r78j/

1.OLED&按键

首先第一步是需要移植I2C显示屏代码

移植请看：https://bbs.elecfans.com/jishu_1999539_1_1.html

按键使用到的是OLED上面的两个按键，一个控制左一个控制右，HI3861上的按键时选中

2.扫雷代码

在OLED初始化启动之后调用mineclear_Start函数

static_library("mineclear") {sources = ["mineclear.c"]include_dirs = ["//domains/iot/link/mineclear","//kernel/liteos_m/components/cmsis/2.0","//utils/native/lite/include","//kernel/liteos_m/components/cmsis/2.0","//base/iot_hardware/interfaces/kits/wifiiot_lite","//foundation/communication/interfaces/kits/wifi_lite/wifiservice","//domains/iot/link/ssd1306",]
}
