C++ (Cpp) Sign::segmentCount示例

void WavePixels::run(Sign &sign, EffectData &data, uint8_t ci){
  uint16_t angle = (millis() % cycleTime[ci])*UINT16_MAX/cycleTime[ci];

  int16_t delta_hue = hueA[ci] * sin16(angle)/UINT16_MAX;
  uint16_t seg_count = sign.segmentCount();

  bool on = (ci == 0);

  for(uint8_t i=0; i < seg_count; i++){
    Segment *curr_seg = sign.segments[i];

    if(curr_seg -> isOn == on){
      curr_seg -> setColor(color[ci]);
      delta_hue = -delta_hue;
      int16_t hue_add = delta_hue;

      uint8_t pixel_count = curr_seg -> pixelCount();
