请教: 大神帮忙看看 LVGL 8.0 表盘设置动态刷新导致重启
平台：esp32platformio 加插件方式开发arduino esp32 导入了LVGL 8.0arduino 这里使用C++ 开发的 搞起来非常不方便，很多函数不知道如何调用。
现在打算用LVGL 做个车速表盘，用lv_meter 的demo 跑起来，但是demo只初始化一次就用动画方式无线刷新表盘了。
实际用起来需要函数调用周期性刷新的 所以 将 动态刷新部分抽象出了一个函数供外部调用，就是这个接口 TemplateView::Screen_update(int speed)
这个接口放到TemplateView 文件中 初始化部分调用 是能够正常显示的，说明函数功能正常的。
但是把这个接口放到
/*2022-6-5 19:07:31
**共外部调用
**
*/
void TemplateView::Screen_update(int speed)
{
static int pre_value =0;
TemplateView* instance = (TemplateView*)timer->user_data;
Serial.println(speed);
/*2022年6月5日 20:15:34
**全注释掉这里就不重启了
**
*/
#if 0
if(speed>1)
{
lv_anim_init(&a);
lv_anim_set_exec_cb(&a,set_value);
lv_anim_set_var(&a, indic);
lv_anim_set_values(&a, pre_value, speed);
Serial.println(pre_value);
lv_anim_set_time(&a, 100);
lv_anim_set_path_cb(&a, &lv_anim_path_overshoot); /* 设置路径（曲线） */
lv_anim_start(&a);
pre_value = speed;
}
#endif
}
外部文件 Template调用时 不注释 lv_meter 相关代码（#if 0注释部分）就会重启， 注释掉lv_meter 就不会重启，说明lv_meter 相关代码导致的重启。
请大神帮忙定位原因，是不是lv_meter 不能放到别的文件里去调用？ 为什么一执行就重启？主要还是想通过外部的速度去刷新表盘指针。
崩溃时捕获的日志：
