Macro to simplify periodic function call by regular interval in Arduino loop()

loopcall.cpp

#define CALL_LOOP(TIME, FUNC) {static unsigned long cnt_##FUNC_##TIME_counter;\
  if (millis() - cnt_##FUNC_##TIME_counter > (TIME)) {\
    cnt_##FUNC_##TIME_counter = millis();\
    FUNC();}\
  }

void TestFunc()
{
}

void loop()
{
  CALL_LOOP(5000, TestFunc);
}
