Update libroboint?

The TX-Pi setup uses 0.5.3 but 0.5.4 is available:

Check if the newer version can be used easily.

There is no objection against using it. Only major change was support of some new Knobloch devices, which does not bother us in any way.

"new Knobloch devices"? What's that? A TXT successor?

Ah. Never mind. It's for those education traffic lights etc. Now Knobloch could use the TX-Pi to control these. Sounds like a nice feature.

Solution: We clone the master branch of https://gitlab.com/Humpelstilzchen/libroboint
See 6306717

Acc. to the developer the master branch should be stable.

What's the recent status of libroboint? Have lost trace a little bit...

Current state: Unsolved issue.
Erik tried to solve the issue and we discovered, that a bigger delay here:
https://gitlab.com/Humpelstilzchen/libroboint/-/blob/master/lib/libroboint.c#L253
"solves" the problem. If it is set to 2600 it works for Robo LT but not with the Robo IF,
The Robo IF needs a feedback of max. 1 sec.
Increasing the delay may not a be a solution for Robo LT either, since the controller would run 2,5 sec. without being controlled by an algorithm.

Unfortunately, I don't have a Robo IF so I cannot help to solve the problem. This is a real show stopper for our Buster release.

The setup uses the libroboint master branch which works for Pi3.
Will open another issue for the USB problems under Pi4
