synchronizing counters output using NI9401

[domcar]

Hi,

I'm using cDAQ9174 and NI9401; I need to generate two synchronized square waves (using two counters). The two waves could have different frequencies (from 500Hz to 7KHz) and duty cycles, but I need they start at the same time (first rising edge together). Is there a way to synchronize the two tasks? I would prefer without using an external trigger.

Thank you in advance for the answers

Hello Domcar,

 I think the best way to synchronize your two counter outputs would be to use a dummy task as shown in the following link. Could you please take a look?
