into a sampling capacitor until the voltage across this capacitor has reached a specific
threshold. The capacitive sensing acquisition only requires few external components to
operate.
Reliable touch sensing functionality can be quickly and easily implemented using the free
STM32L1xx STMTouch touch sensing firmware library.
3.15 Timers and watchdogs
The ultralow power STM32L15xxx devices include six general-purpose timers, two basic
timers and two watchdog timers.
Table 6 compares the features of the general-purpose and basic timers.
