关于STM32空闲中断

在使用串口接受字符串时，可以使用空闲中断（IDLEIE置1，即可使能空闲中断），这样在接收完一个字符串，进入空闲状态时（IDLE置1）便会激发一个空闲中断。在中断处理函数，我们可以解析这个字符串。需要注意的是，IDLE标志位需要软件清零，否则由于会不断进入中断，而使正常程序无法运行。当再次收到数据时（即RXNE再次置1），等到空闲便会重新进入中断。在STM32F4中，IDLE标志位清零的...[详细]
汽车电子锁屏蔽器到底有多可怕

干扰器是一种信号屏蔽器，主要是由一块芯片和一个无线电发射装置组成。当车主按下遥控器锁门键时，干扰器通过发射与汽车遥控器相同的频率来干扰电子锁接收遥控器信号，使汽车服务器得不到锁门的命令，车主锁门时，虽然也会听到“咔嗒”的声音，但车门并没有真正锁上。待车主误认为车门已锁(其实车门未锁)离开后，嫌疑人将车门打开实施盗窃在过去的几年里，有上百起案件报告了手提包，钱包，公文包和行李被盗，上述所有情...[详细]
电动汽车系统中发动机与变速箱的联系
