pubsubc

This is a minimal MQTT client library in C.

It comes with an adaption layer for the ioLibrary_Driver for the WizNet chips which can be found here https://github.com/Wiznet/ioLibrary_Driver.

You find a fork with a Makefile a STMCubeMX generated project here https://home.hottis.de/gitlab/wolutator/ioLibrary_Driver/-/tree/WolfgangsOwnBranch.

Using this adaption layer you should find it easy to adjust it for other platforms.

This work is directly derived from the famous PubSubClient library of Nick O'Leary, which can be found at https://pubsubclient.knolleary.net/

It is most or less a plain C rewrite.

All honour for this working MQTT client library goes to Nick O'Leary, all blame for bugs in the C port shall go to me.
