分享资料个
以AVR单片机ATmega8L为核心，提出了一种智能LED紧急刹车灯的软硬件设计方案。通过A/D转换电路将采集到的MMAl260加速度传感器信号输入单片机，并与门限值（设定值）相比较，控制LED车灯的闪烁，以此警示后面的司机，避免发生追尾事故。

Abstract: The hardware and software of the intelligent Led emergency stop light are designed based on ATmega8L MCU．The signals collected by MMA1260 acceleration sensor are inputted in MCU through the A/D converter circuit，and compared with the threshold (set of) to control the Scintillation of LED lights，so this can warn the driver behind to avoid rear-end accidents．
Key words: intelligent LED emergency stop light, ATmega8L, MMA1260D
