There is a try-catch functionality in matlab that (to me) sort of looks
like java's try-catch. There is no generic multi-threading support in
Matlab like there is in java as far as I know. That being said, Matlab
always ships with a complete JRE so you can always use java's
multi-threading. Mathworks doesn't actively advertise this fact, probably
because they want their users to use the matlab language and matlab
solutions (like their parallel computing toolbox e.g.) instead of java.
I was also thinking about a boilerplate-like function. You could even make
it universal for octave and matlab when you detect in which environment it
runs. If you are interested I could make something like that e.g. a
function that looks like this: "myioio = createIOIO('COM4');", and "myioio
= createIOIO;" to do auto probing. Or maybe a `connectIOIO` function that
also connects. I could also do other examples, e.g. to plot the analog
inputs.
But since I don't fully understand ioiolib and don't know how things like
exceptions, events, connections over TCP and bluetooth should work in this
context, I'm not sure what a proper boilerplate function should look like
beyond a simple com-port connection. Also, ideally I imagine that it would
be nice when the firmware version is detected, and automatically the proper
PC side ioiolib version is used (maybe even resolve and use the correct
versions of the dependancies, jna and purejavacomm). Or at least give a
warning when there is a mismatch.
That's why I thought I'd post just simple one-file example scripts that can
easlily be adapted for other means. That way at least I don't obstruct
other solutions by hiding or obscuring the mechanisms involved behind
potentially ill designed abstraction layers.
