I’m trying to setup some experiments to utilize the GRC environment. As
part of it, I’m reading samples off an ADC connected to a
connected to PC via UART/RS232 Serial, using PySerial module.
I have been trying to write a Source block for GR, where a listening
would read the ADC samples from the Serial port into a global variable,
then, another thread wud “probably” pass the data into a
(like?) block within a hier2 block.
Well, that was just the idea. But I guess the system doesn’t work this
I’m not sure whether I’m entering the message-blocks domain, which is
expected to support such packetised(?) data. I read in the GRC Wiki -
custom blocks” section that it might be possible to make such “special”
functionality encapsulated in a block-diagram-safe block. Any suitable
Conflicting again is the thought that ultimately samples from USRP and
sources are also probably caught in chunks and assembled into streams.
the sources for them look too complex and spread out for me to look into
I hope someone will make it clear for me and point me in a direction I
look for a quick hack.
