请问用一块PCI6221上的DI/O口怎么产生脉冲信号。我需要产生两组组脉冲信号来控制步进电机。可变频率的脉冲信号由两个counter来生成，打算用DI/O口来产生方向信号，不知道这样行不行？
I'm using a PCI6221 to generate two pulse trains to control a step motor. The finite pulse train can be generated by two counters to be used as the velocity control signal. Now i want to use the DI/O to generate another pulse train as the direction control signal. Anyone konws this is right or worng? and how to generate pulse train by the DI/O without using the counters?
Thanks a lot.
