延迟脉冲上电

arthur568 — 2018年4月14日星期六00:59:40 +0000

对于如此长的持续时间，我们级联两个CNT/DLY块，其中第一个组件被配置为一个计数器，并用作第二个组件的时钟，第二个组件被配置为一个延迟块。我们试过在DLY IN端口上使用POR，但这导致信号马上上升。似乎一旦POR完成(POR变高)，Delay块就会对值进行采样，从而最终得到初始值。

解决方案，似乎是工作是使用DFF与POR在nRESET设置初始极性为低。DFF的时钟来自第一个计数器使用的相同的OSC0/64。这是产生这种延迟正脉冲的可靠方法吗?你有更好的方法来完成这个简单的任务吗?

谢谢，我们真的很感谢你的帮助!

I saw that the question of possibly using the quadrature decoder for this came up in the forum a while ago but it wasn't answered. Could the quadrature decoder be used to count low frequency pulses? The plan would be to poll periodically to calculate event rates reported by the sensor.

If this is possible, are the quadrature decoder counters running in extended sleep mode? We'd like to perform this function without a GPIO interrupt for each pulse that would require the system to be awake to count pulses..

Thanks, Max
