硬件: Digital I/O (DIO)>>High-Speed Digital I/O>>PXI 6541
问题:我想在HSDIO中使用外部输入的脉冲信号来多次触发发送自定义的波形。即实现外部硬件可重复触发的功能,就是每检测到硬件端口的脉冲上升沿就发送一组自定义的波形。该如何实现?

Hi,
我在LabVIEW裡面有看到PXI 6541 trigger相關的範例,叫做「Dynamic Acquisition Hardware Start Trigger.vi」,你可以嘗試看看使用這個範例去做觸發

您好,谢谢您的回复,但是Dynamic Acquisition Hardware Start Trigger.vi这个例子我看过,好像只能首次检测到硬件上升沿时,触发一次,并不能进行连续的可重复的触发。

Hi 您好,
我在網路上有找到HSDIO做retrigger功能的文章,你看看有沒有幫助呢?
