System configuration controller and routing interface
The system configuration controller provides the capability to remap some alternate
functions on different I/O ports. TIM4 and ADC1 DMA channels can also be remapped.
The highly flexible routing interface controls the routing of internal analog signals to ADC1,
COMP1, COMP2, and the internal reference voltage V
registers for efficiently managing the charge transfer acquisition sequence
Touchsensing).
Touchsensing
Low density STM8L15xxx devices provide a simple solution for adding capacitive sensing
functionality to any application. Capacitive sensing technology is able to detect finger
presence near an electrode which is protected from direct touch by a dielectric (example,
glass, plastic). The capacitive variation introduced by a finger (or any conductive object) is
measured using a proven implementation based on a surface charge transfer acquisition
principle. It consists of charging the electrode capacitance and then transferring a part of the
accumulated charges into a sampling capacitor until the voltage across this capacitor has
reached a specific threshold. In Low density STM8L15xxx devices, the acquisition sequence
is managed either by software or by hardware and it involves analog I/O groups, the routing
interface, and timers.Reliable touch sensing solutions can be quickly and easily
implemented using the free STM8 Touch Sensing Library.
Timers
Low density STM8L15x devices contain two 16-bit general purpose timers (TIM2 and TIM3)
and one 8-bit basic timer (TIM4).
All the timers can be served by DMA1.
