I wanted to use RTC Circuit for Supercap.I have designed circuit (Check Attached snapshot).but i dont get back up time? can anyone explain do we need to do any provision in controller.It seems that capacitor is discharging very fast
Hi AScha,Thank You.For better understanding, I have attached Snapshot form STM32F777 Datasheet.Also please confirm it is applicable for SPI Channel as well.In my Case, I have VDD:3.3VSo VIH=(0.45*VDD+0.3)/(0.7*VDD)=(0.45*3.3+0.3)/(0.7*3.3)=0.77Vis it...
Thanks Eleon.Sometime i could read 3014 mg when i placed from one location to another.How acceleration it calculated? can you brief one example (Sorry for Dumb question but i am new for this)
I am using STEVAL-SMARTAG1 anf NFC Phone,With the help of App ST NFC Sensor app.. i only can read 1024 mg acceleration/min.What does this means? can you explain how mg is related with Acceleration?
Yes.. by removing zener.. Supercap voltage is decreasing as per expectations.BZX84-B zener diode has reverse current of 5uA at Reverse leakage voltage of 1V.in our case we have zero reverse voltage.Still i dont understand which parameter of Datasheet...
