Posted on March 05, 2015 at 14:17Dear friends, please help.
I make a touch switch on the 3 buttons. I use microcontroller STM32L151 and its hardware ''touch sensing''.
The challenge is to ''touch switch'' with CR2032 battery (225mAh) worked for several years. Average consumption should fall less than 10 microamps.
Tell me please, what is the minimum time to poll the key-touch enough?
It need for wake up the microcontroller on the minimum amount of time.
Sincerely, Roman.
