Re: vector source python block

Thanks Barru but i have a minor problem opening the grc file

Loading: "C:\Users\infrared\Documents\gnuradi_whatevers\MorseGen.grc"

Error: file:/C:/Users/infrared/Documents/gnuradi_whatevers/MorseGen.grc:1:1:FATAL:PARSER:ERR_DOCUMENT_EMPTY: Start tag expected, '<' not found

>>> Failure

Hi,

Without seeing your flowgraph, it is hard to tell what you plan to do
with the vectors. In gereral, the "speed" ultimately is determined by
input and/or output devices such as USB or a sound card. If you have
neither one, a throttle block will limit the throughput.

As an example of a custom vector source, see
https://github.com/duggabe/gr-morse-code-gen which generates vectors of
dots and dashes for Morse Code. If you start at the audio output (48khz)
and work backwards, you will see how the sample rates determine the
desired speed in words per minute.

If you haven't already done so, it would be helpful for you to work
through the

Let us know if you have more specific questions.

Best wishes,
