## phase bare-metal
### RTC
- [ ] 每秒打印RTC
- [ ] usart 菜单更新设置RTC time
- [ ] save RTC to flash, restore after power on
- [ ] 倒计时闹钟，支持多个，且不重复时间




### KEY & LED
- [x] 1个 heartbeat led， 周期默认2s,使用systick中断
- [x] default 每5秒两个流水灯切换
- [ ] 中断捕捉按键，sw1按键控制流水灯切换周期+1, sw2 控制周期 -1,上下限10s:1s

### system
- [ ] OTA
- [ ] record run time long


## phase rtos
- [ ] porting freeRTOS
- [ ] include bare-metal tasks
- [ ] add ble tasks
- [ ] add ESP8266 AT cmd task
- [ ] add NFC task
- [ ] add finger sensor task
- [ ] add EPD task
- [ ] add fatFS

## external module
- [ ] RGB LED
- [ ] EPD as display
save and restore rtc from register
epd display
epd display with LVGL
from bare-metal to freeRTOS
from bare-metal to zeyphr
from bare-metal to rt-thread
- [ ] 超声波模块




# question
* flash 从第206page开始，erase会进入hardfault。
实际page只有 205page， datasheet 显示255page.


# manual
 read flash, usart
