NI-9263 : Get signal generation progression

[Flow75]

Hello,

I've a NI-9263 module to generate output signal.

I would like to know if there is some kind of progress value ?

I've tried EveryNSamplesWritten event but I've this message :

"NationalInstruments.DAQmx.DaqException : 'Requested Every N Samples Event Interval is not supported for the given Data Transfer Mechanism and buffer size.
To keep DMA or USB Bulk as the Data Transfer Mechanism, modify the buffer size and/or the Every N Samples Event Interval so the buffer size is an even multiple of the Every N Samples Event Interval. To keep the same Every N Samples Event Interval and buffer size, change the Data Transfer Mechanism to Interrupts if supported."

Thx.

Hello Flow75,

Before being able to help you, there are a few questions that I have:

• Which softwares and drivers are you using for your signal generation ?
• What it your OS and what are the references of your other hardware devices (especially the cDAQ device) ?
• What do you mean by a "kind of progress value" ? Does it mean that you want to generate a slowly evolving signal ? An evolving generation rate ? Or does it mean something else ?
• What is the context and the goals of this signal generation ?

By giving us more details, it's going to be easier for us to help you ! 😉
