stm8l152的DMA,uart，rtc，io中断，关机唤醒模式-stm8l152 of DMA, uart, rtc, io interruption, shutdown wake mode

stm8l系列单片机低功耗使用例程，mcu进入休眠，可通过rtc进行唤醒，从而使功耗降到更低(The stm8l series of single-chip microcomputer's low-power use routine, MCU enters dormancy, can be awakened by RTC, which can reduce the power consumption to lower)

STM8 RTC 唤醒带led显示(STM8 RTC wake band led display)

STM8 低功耗模式+rtc+中断唤醒(STM8 low power mode +rtc+ interrupt wakeup)
