关于ledseq逻辑思路解释，看了3边了，都是卡在这里，还有遥控器的beepseq也是这个

static void runLedseq( xTimerHandle xTimer )
{
bool leave = false;
const ledseq_t *step;
led_e led = (led_e)pvTimerGetTimerID(xTimer);
if (!ledseqEnabled) return;
while(!leave)
{
  int prio = activeSeq[led];
  if (prio == LEDSEQ_STOP)
return;
  step = &sequences[prio][state[led][prio]];
  state[led][prio]++;
  xSemaphoreTake(ledseqSem, portMAX_DELAY);
  switch(step->action)
  {
case LEDSEQ_LOOP:
state[led][prio] = 0;
break;
case LEDSEQ_STOP:
state[led][prio] = LEDSEQ_STOP;
updateActive(led);
break;
default:  /*LED定时*/
ledSet(led, step->value); /*定时step->value*/
if (step->action == 0)
   break;
xTimerChangePeriod(xTimer, step->action, 0);
xTimerStart(xTimer, 0);
leave=true;
break;
  }
  xSemaphoreGive(ledseqSem);
}
我想不明白这个文件是怎么确定led的逻辑的，想大佬解释一下，卡了很久了
