Power consumption??
Hi.
I have an application that requires low power. The lowest I get is about 0.6mA in deepsleep. To my understanding it should be able to achieve a lower level (a few uAmps).
I have found there is a header in the hal library called STM32L1xx_hal_pwr_h, that provides some functions but I don't know how to use them properly...
Does anyone have an example or some info on how to reduce power consumption?
Thanks.

In the SetRTC.lib, you will see void goto_standby(void) function.
You can modify clock on/off control and others.

In addition, you can see my BMP180 program at below.

Sorry this is only Japanese but I have reached 16.5uA. total current at STOP mode.
