Hi everybody,
I’m trying to write samples acquired with the couple USRP2-WBX directly
on
the hard disk thanks to the file sink. I’m using GRC and the decim
factor is
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
limited
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
additional questions.
- Instead of write complex floats directly on the disk can i make this
:
USRP2 source in short mode → type conversion : short in char → writing
on
the disk with file_sink in char mode? - I read that it was possible to write directly on the RAM with the
unix
command tmpfs. Any description of the procedure ? - Other tricks or advice ?
Thanks in advance at all
