串口通讯解析数据时需要花时间,如果在解析数据时,串口又接收1帧数据该怎么办啊? |

最佳答案处理跟不上接收只能舍弃或者换高性能单片机,比如池子进水快出水慢早晚要溢出 dma也只是稍微缓解点节约点接收时间,节约的这一点时间还不够处理用就换主频高的单片机要么间隔着舍弃一些帧

He who fights with monsters should look to it that he himself does not become a monster, when you gaze long into the abyss, the abyss also gazes into you.
过于执着就会陷入其中,迷失自己,困住自己。 |
