Generating two digital waveform signals triggered by an X Series input channel with NI-DAQmx

[did.rider38]

Hello,
I need your help. I am unable to generate two signals from a table on port 0 simultaneously. The DAQmx “write” function indicates that it is already busy. Do you have any idea what the program structure should be to send a waveform signal created from a digital array to channel port0(0) and another waveform signal of the same array size to channel port 0(1) at the same time? Please note that I am using a virtual channel to trigger the generation of these two channels.
Best regards

You need to combine all hardware timed DIO channels into the same task as there is only one DO timing engine on X-series DAQ.

Okay, I put the physical DIO channels on the same task, at least I hope so. You'll find the IV in your email.
But now I'm getting another error saying: 1 task and 2 data points...

Please try with the option "one channel for each line"

Great!
The Vi no longer has any bugs!!!
Well, I don't have any output signal....
