Forum: GNU Radio Read From File

Hello,

I am trying to control a selector from an external source.  As of now, I
can control the selector with a GUI Widget and/or a variable.  The
selector chooses between signal sources that produce different sine
waves and sends it to the USRP sink.

The external source will likely be a file because I have written a C
program (acting as the user interface) to read in the data from the user
and do all of the encoding and interleaving.

If I could read in the file bit-by-bit to GNU Radio based on a sampling
rate and control the selector with it, I could transmit an ALE frame.

If anyone has done a similar task and has any guidance in the matter, I
would great appreciate it.
