M5 stack chan：1、在线编程：下载安装Burner-安装UIFlow_Core2，按https://docs.m5stack.com/en/quick_start/m5core/uiflow指示得到API KEY，重启在线编辑。M5StickC PLUS2编程地址为https://uiflow2.m5stack.com；M5Stack-Core编程地址为https://flow.m5stack.com。2、M5DIAL：Select Tools->Development Board:->M5Stack Arduino, the main control used by M5Dial is M5StampS3, so select (STAMP-S3) in this option.地址：https://docs.m5stack.com/en/core/M5Dial。
3、M5StickC PLUS2：Select Tools->Development board:->M5Stack Arduino, and select the corresponding development board configuration according to the device we are using (M5StickC-Plus2)。地址：https://docs.m5stack.com/en/products?id=core
4、选中ESP32 Arduino中的M5Stack-Core-ESP32或M5Stack-Core2，忽略错误提示，上传。时间不正确，安装I2C BM8563 RTC库，使用更改示例中的BM8563_SET中的时间上传，再将日历代码重传一次。
