Pulse Counter Example

This example demonstrates how to configure and use the Pulse Counter APIs.

 
#include <inttypes.h>
#include <stdio.h>
#include "flex.h"
 
#define APPLICATION_NAME "Pulse Counter Example"
 
// Number of pulses that will cause a wakeup event.
#define PULSE_WAKEUP_COUNT 6
 
static void RunsOnPulseCounterEvent() {
  printf("Woken up by Pulse Counter @ %u\n", (unsigned int)FLEX_TimeGet());
 
  printf("Current pulse counter value: %" PRIu32 "\n", (uint32_t)FLEX_PulseCounterGet());
}
 
void FLEX_AppInit() {
  printf("%s\n", APPLICATION_NAME);
 
  // Initialise to generate event every PULSE_WAKEUP_COUNT pulses
  if (FLEX_PulseCounterInit(PULSE_WAKEUP_COUNT, FLEX_PCNT_DEFAULT_OPTIONS)) {
    printf("Failed to initialise pulse counter\n");
  }
 
  // Enable pulse counter event
  FLEX_PulseCounterHandlerModify(RunsOnPulseCounterEvent, FLEX_HANDLER_MODIFY_ADD);
}
