最佳答案你不清空buff,buff里面的数据还是上次的12345,USART_RX_STA&0x3fff=5,这次接收到的数据是67,那么buff里的数据是67345,但是此时的USART_RX_STA&0x3fff=2了。然后你现实的是整个buff, Show_Str(320,350,400,24,USART_RX_BUF,24,0);所以才有你看到的残留

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。 |
