板子还没有到。。。做项目,想先确认再买。 我下载了资料,里面bk7252手册里关于电源管理是这样描述的,英语不太好,感觉deep sleep mode描述是说外部中断和定时器超时都可以唤醒该模式,不知道这个模式实际功耗多少。 To reduce power, the BK7252 can be put in three low power modes as follows. Shutdown – In this mode all circuits are powered down when CEN = 0, and the system will power on only after CEN back and keep high for a few milliseconds. The software could also shut down the system and could wake up from GPIO13. Deep sleep mode – In this mode all circuits are powered down except the GPIO and always on logic, that any GPIO edge transition or always on timer time out event can power up the system again. The retention register could keep it contents at this mode. Normal Standby – In this mode the MCU stop running and all peripheral interrupt can resume MCU. Low voltage Standby – In this mode the MCU and all digital logic stop their clock, and the power supply of them decrease to a much lower retention voltage, that the current could be much lower. In this mode, only GPIO and RTC timer could resume the system to run mode with normal voltage. 电流描述里说的是可以,不确认实际上能不能实现。 另外这颗芯片adc准不准,之前用bk3633,adc偏差几乎不能用。 |
