I am trying to get MATLAB to read a stream of incoming data via a serial port using callback ,
This is a peice of my code
s = serialport("COM4", 115200)
function readSerialData(src,evt)
src.UserData = data;
end
Whenever I type readline(S), I get a one time result but I want it to be automatic whenever a new stream of data arrive, hence my use of callback function.
So whenver I type
configureCallback ("COM4", "terminator" , @ readSerialData)
I get a non stopping error:
Error in asyncio.Channel/onDataReceived (line 487)
notify(obj.InputStream, 'DataWritten', ...
Error in asyncio.Channel>@(source,data)obj.onDataReceived() (line 425)
@(source, data) obj.onDataReceived());
> In asyncio/Channel/onDataReceived (line 487)
In asyncio.Channel>@(source,data)obj.onDataReceived() (line 425)
