Hello,
I'm looking to customize SR select commands on a Portsdown 2020 or 4. Let me explain, when I select SR 2000 or SR 4000 I would like to launch a bash script that sends a command to an external module. Writing the script is not a problem for me but where to place the command line to launch it is my question. I've already looked in the scripts directory but I admit I'm a little lost. Help would be welcome.

Hi Robert

There is no in-built mechanism to run a script when the SR is changed.

You would either need to modify the selectSR function in rpidatvtouch4.c https://github.com/davecrump/portsdown4 ... h4.c#L8163 and then recompile, or modify ctlSR.sh https://github.com/davecrump/portsdown4 ... s/ctlSR.sh to call a script.

Both of these changes would be over-written by future software updates.

Hi Dave,

Thanks for info.

I had an intuition as to the obligation to modify a source file and to have to recompile, you confirm it to me.
I plan to run in IQ mode and seeing the ctlsr.sh file in which limeSDR is mentioned I thought to myself that this isn't the right file. Can you confirm it?

It is obvious that this kind of customization is overwritten by a software update and therefore it must be managed.

Hi Robert

If you are running in IQ mode then you must be using a Portsdown 2020, so the correct link is https://github.com/davecrump/portsdown- ... s/ctlSR.sh

This script is called on SR Change, but I think is called at other times as well. You'll need tio do some tests to check.

Hi Dave,

Thanks for the info about the IQ mode which only works with Portsdown 2020. A few days ago I analyzed the differences between the GPIO breakout boards of each versions. Unsure of being able to use Portsdown 4 in this mode, I ordered the board for 2020. I also have a Raspberry PI 3B+ in my stock so ready to experiment.

Thanks again for your help.

Robert.
