Hello,
I have a application running very well and I was wondering in an UPGRADE to myRIO-1900, since it is based on FPGA and has wireless connection.
The basic validation was configure acquisition rate and number os samples, and it seemed not to be so straightforward (https://forums.ni.com/t5/LabVIEW/How-to-fft-the-myRIO-accelorometer-readings/td-p/3317681), the applications used in community are slow for medium frequency acquisition and not scalable.
Did I put too much credit believing that a myRIO device could make a simple acquisition and FFT transform? Is it not the correct device to embedded signal analysis, should I look for an arduino application more useful?
Hope you can help me with this issue, I still believe that this application can come true
Best Regards,

Hey mbriago,
I am not sure what "medium frequency acquisition" and "not scalable" means to you, so I can't give you an answer righ off the bat. On the other hand, I can definetly say that a myRIO can have a better performance for Data Acquisition and FFT than Arduino.
Comparing Sampling Rates
Comparing Processing.
