Hi,

To do a recording of data to an xml file each trigger, you will need to write an app that does it. The existing applications don't have that functionality.

You can start with edgo's calibration aware acquire tool and modify it to suit your needs. You'd need to set the trigger correctly, and then include a mechanism to write xml data from the acquired samples when a trigger event occurs.

Happy hacking

I'd say, if it is a train of digital pulses, connect it to the external trigger input on E1.

I am pretty sure that the Red Pitaya does not have any software to write excel files. As before with the xml, you would need to come up with your own. Search the googles and stackoverflows for suitable solutions.

okk


then tell me other technique to store my acquired file.

For example we have PuTTy commands and with the use of acquire utility i can save the acquired file into tmp file in <root >. and then it can be copied with winSCP. so can u suggest me the what should i do for this at the time of triggering??

You will need to change the acquire utility.
Right now, acquire can only do "Auto"-trigger. You must change acquire.c so that it can set trigger mode "Normal" and trigger source "External".
Then, each time you call acquire, it will wait until a trigger event occurs and output the acquired data. Save these values and call acquire again ...

Hello,

Currently not. But we hope that drivers for LabVIEW will be available in a month or two.

Stay tuned!
