GameFi's emotional guidance has made some inferior chain games popular.A considerable number of game projects only focus on issuing tokens,selling blind boxes and selling NFT in the early stage.After the early harvest,make the P2E model more attractive and create a truly fun P2E metauniverse.The returned funds are not used for production

　　什么是元宇宙？

　　元宇宙会是由科技公司创建和运营的虚拟世界，软件I8O系统2857开发8624还是结合物理和数字化技术的增强现实体验？出现在手机上的位置服务和博物馆、商店中的虚拟物品展示都属于元宇宙这个范畴吗？以上关于元宇宙的两种观点都是正确的。

　　元宇宙是互联网的下一次迭代，人类与其的交互模式将是虚拟、实时、三维和物理体验的组合，所有人的工作、购买和消费方式都将发生翻天覆地的变化。这种变化对人类社会和生活的影响将比智能手机的影响更加深远。

　　But when it comes to the real return on investment of enterprises,we are still in the initial stage.Now is the time to experiment,invest and innovate in the scenario based on the universe.

　　Whether they happen on the Internet or in augmented reality space,the key is to focus on the business results and objectives of creating virtual world experience.Although enterprises and media pay more attention to the marketing and income-generating potential of MetaUniverse,various potential MetaUniverse applications can not be underestimated.In addition to entertainment,enterprises can also use MetaUniverse to optimize business operations and enrich staff collaboration and training experience.

　　Stack is defined here_ Size and Heap Heap_ The size of Size.The stack stores local variables and stack data during program nesting.The heap can be used for dynamic memory allocation and release.Note that global variables do not occupy the stack and heap in the BSS segment__ Vectors gives the name of the interrupt vector table and the service function.Define the corresponding service function in the C file:

　　//定时器3中断服务函数

　　void TIM3_IRQHandler(void)

　　{

　　if(TIM_GetITStatus(TIM3,TIM_IT_Update)==SET)//溢出中断

　　{

　　//OS_TimeMS++;

　　printf("frame:%drn",ov_frame);//打印帧率

　　//printf("jpeg_data_len:%drn",jpeg_data_len);//打印帧率

　　ov_frame=0;

　　}

　　TIM_ClearITPendingBit(TIM3,TIM_IT_Update);//清除中断标志位

　　}
