Copy-paste the following code to your user application:

uint32_t measure_result;
enum freqm_status status;

freqm_start_measure(&freqm_instance);
while ((status = freqm_get_result_value(&freqm_instance, &measure_result))
        == FREQM_STATUS_MEASURE_BUSY) {
};
switch(status) {
    case FREQM_STATUS_MEASURE_DONE:
        LED_On(LED_0_PIN);
        while (true) {
        }
    case FREQM_STATUS_CNT_OVERFLOW:
        freqm_clear_overflow(&freqm_instance);
        while (true) {
            LED_Toggle(LED_0_PIN);
            volatile uint32_t delay = 50000;
            while(delay--) {
            }
        }
    default:
