Configuring the STM8S touch sensing library
In applications using the STM8S touch sensing library, all the library sources and header
files must be added to the project.
stm8_tsl_rc_api.c defines the functions used to communicate between the STM8S touch
sensing library and the user code. It is associated with stm8_tsl_rc_api.h that contains the
API function prototypes, structures, variables and constants. stm8_tsl_rc_api.h must be
included in the main() routine.
STM8_TSL_RC_Configuration.h contains the library static configuration parameters that
must be set in compliance with your application hardware. Check that the define statements
are filled in with the correct values.
See
single touch sensing button of STM8S-DISCOVERY (TS1).
The other define statements must remain unchanged (thresholds, integrator settings, IIR
filter settings,...).
The STM8_TSL_RC_Configuration.h file can be updated to support up to 24 keys and 2
wheels or sliders.
