The Table below describes the various configuration parameters corresponding to the ATtiny20.
162
Setup the desired device clock using the init_system() in main.c
Using the init_timer(), setup the Timer ISR such that the Timer Interrupt occurs every
20ms . Enable the ADC and configure in Free running mode.
Using the touch_config_tiny20.h configuration file,
1. Set the desired number of Sensors.
2. Set the Individual sensor Threshold, Hysteresis, Recalibration Threshold and Delay
cycle values.
3. Set the desired Sensor Global acquisition parameters using the
IAR Project->Linker options.
4. The DEF_QT_ADC_CHANNEL_START_INDEX Linker option can be used to set
the starting ADC Channel.
Add any Host Application
(a Sample LED application is available with the Tin20 EK IAR Example project).
