本样例提供了一个HarmonyOS IoT硬件接口的SSD1306 OLED屏驱动库其功能如下
内置了128*64 bit的内存缓冲区支持全屏刷新;优化了屏幕刷新速率实测最大帧率10fps;libm_port
是从musl libc中抽取的 sin和 cos的实现
用于规避链接Hi3861 SDK中的libm_flash.a报错的问题;gif2imgs.py
可用于将gif动图中的帧分离出来;
依赖 pillow 包可以使用 pip install pillow 命令安装img2code.py
可用于将图片转为C数组每个字节表示8个像素
依赖 opecv-python 包可以使用 pip install opencv-python 命令安装使用Harmony OS的IoT硬件接口;接口简洁易于使用、易于移植;内置了测试程序可直接进行测试;
