24.8.2.1.2 Code
Add to the main application source file, before any functions:
- SAM D21 Xplained Pro.
#define PWM_MODULE EXT1_PWM_MODULE
#define PWM_OUT_PIN EXT1_PWM_0_PIN
#define PWM_OUT_MUX EXT1_PWM_0_MUX
- SAM D20 Xplained Pro.
Add to the main application source file, outside of any functions:#define PWM_MODULE EXT1_PWM_MODULE
#define PWM_OUT_PIN EXT1_PWM_0_PIN
#define PWM_OUT_MUX EXT1_PWM_0_MUX
Copy-paste the following setup code to your user application:struct
tc_module tc_instance;
Add to user application initialization (typically the start of main()):void
configure_tc(
void
)
{
struct
tc_config config_tc;
tc_get_config_defaults(&config_tc);
config_tc.counter_size = TC_COUNTER_SIZE_16BIT;
config_tc.wave_generation = TC_WAVE_GENERATION_MATCH_FREQ;
config_tc.counter_16_bit.compare_capture_channel[0] = 4000;
config_tc.pwm_channel[0].enabled =
true
;
config_tc.pwm_channel[0].pin_out = PWM_OUT_PIN;
config_tc.pwm_channel[0].pin_mux = PWM_OUT_MUX;
tc_init(&tc_instance, PWM_MODULE, &config_tc);
tc_enable(&tc_instance);
}
configure_tc();
