目前市场上最新的三轴数字微机电系统(MEMS)加速度计,大多具备一或两个中断输出接脚,并可根据所侦测到的加速度数据,实现各种中断功能;同时让外部主处理器能同步执行其它任务,或进入低功耗睡眠模式,减少电力消耗。数字MEMS加速度计通常有一或两个中断输出接脚,用于连接一个外部主处理器的输入/输出(I/O)接脚,可在后台监控目标物体的加速度动作,同时让外部主处理器可同步执行其它任务,或进入低功耗睡眠模式。当加速度计发现一个中断信息时,主处理器立即从睡眠中唤醒,检查中断是否须处理。
Most recent triaxial digital MEMS accelerometers currently on the market have one or two interrupt output pins and can perform various interrupt functions based on the detected acceleration data while allowing external main processing The device can perform other tasks simultaneously, or enter low-power sleep mode to reduce power consumption. Digital MEMS accelerometers typically have one or two interrupt output pins that connect to an external host processor’s input / output (I / O) pin to monitor the acceleration of the target object in the background while allowing the external main processor Other tasks can be performed simultaneously, or into low-power sleep mode. When the accelerometer discovers an interrupt message, the main processor immediately wakes up from sleep and checks if the interrupt needs to be processed.
