Re: [Discuss-gnuradio] Where to Start?

[dave]

Ok, I will look into using the GRC as a first step.

I am hoping to work with the USRP eventually.  If someone knows some up to date tutorials specifically for USRP that would be appreciated as well. 

I see now that the mc4020 code was intended to gather the FM from a cable modem over a parallel port.  That is not general code or USRP code at all.

The info at:   http://www.joshknows.com/gnuradio    ...does have some gnuradio + USRP specific code, but it's very short.  Maybe I can figure it out by looking at that along with the "how to write a signal block" page.

Thanks,
Dave

Hello,

here:

It has many problems as you know.  I found a page on 
joshknows.com:

shame as it was interesting.  I'm not sure where to 
go.

The MC4020 example was unrelated to USRP1 in any way as far as I know.  It was for a piece of

For now I will continue reading this and then try the "how to write a

page.

My ultimate goal is to emulate 802.15.4 in USRP (which has been done 
before)
and test some variations in the MAC layer.  For now, I just need to 
learn
gnuradio 
though!

Many thought experiments can be conducted using Gnu Radio Companion (GRC), which gives you a graphical, Lego-Like
