Hi everybody,
I still working when I have little time on my project, and have questions about save power.
On my project ( a wireless remote ) is a batterie Li-ion 3,7V 1000mA.
in my project I have the powerdown mode that is active everytime. The MCU is wake up by a external interrupt.
But the MCU must when is running in normal mode read a ADC to see the voltage off the battery.
In the first step, during the developpement, I don't have configure the ADC, and in powerdown mode, the circuitry is about 0,100mA.
and it's not very good results, but it's not too bad !
But now I have configure the ADC with 1,1V in internal reference, I read My battery voltage, stop the ADC disable the ADC and goes in powerdown mode. And what I don't understand is that my result is 0,485mA !!!!! HERE IS SO BAD !!!!!
I don't understand why if I disable the ADC the result is not so before (0,100mA)
Can anybody explain me why ? and give me how I can do to save the max powwer as possible ?
Thanks everybody.
Best regards
Vincent
