Thanks Neel and Johnathan. I have used UNetBootin to create a new GNU Radio
live but I have set the persistent memory to 4 GB (Thanks to Richard Bell
advice). It is zero by default so you end up with no memory to save your
work by default and it seems it does not set it beyond 4GB. It feels like

Hi Marcus,
My first idea is: python has to sample the 256 samples (for one
period) from lookup table in exactly one second. So i think i need a
timer which calls the next sample in the lookup table all 3,9 ms.
My first idea above was to produce the sine wave from the lookup table
(which i ha

yes, this is DSP, so all we care about is rates relative to the sampling
rate. I got into the habit of thinking of the sampling rate as always
being "1"
Hi Marcus,
Well, first:
Signal Source can't produce 8bit signed integers by itself, so you'll
have to convert whatever you configure the signal source for to char,
eg. you could set it to "float" and use the "float to char"
conversion. Make sure the result has amplitude 127. Properly configur
Hi Andy,
this is python, so batteries included :)
Use the "import" block to "import math".
then, in the vector source's value field:
[ math.sin(x/(2*math.pi)/num_samples) for x in xrange(num_samples) ]
alternatively, "import numpy" and
numpy.sin(numpy.linspace(0, 2*numpy.pi, num_samples))

Hi Martin,
You can create a lookup table for pretty much anything using a vector
source, it'll accept Python structures as inputs through GRC.
i tested your suggestion and i am asking myself if there is an easy way
to get a lot of lookup table values in to the vector value field of the
vector s
