I’m trying to write samples acquired with the couple USRP2-WBX directly
the hard disk thanks to the file sink. I’m using GRC and the decim
set to 10 (idealy i need a factor 3). Unfortunately the program overruns
(SSSS… on the terminal) that it seems normal to me considering the
write speed of an hard drive.
I’m looking for some “tricks” to be able to write at this sample rate. I
found a previous similar message in the mailing list but i have some
- Instead of write complex floats directly on the disk can i make this
USRP2 source in short mode -> type conversion : short in char -> writing
the disk with file_sink in char mode?
- I read that it was possible to write directly on the RAM with the
command tmpfs. Any description of the procedure ?
- Other tricks or advice ?
Thanks in advance at all
