generic LIN
Hi Fabian,
this is not really an issue, more a proposal. I am really impressed of the code and the encapsulation. It looks like a lot of effort has been put in the driver.
Since a long time I wanted to write a LIN driver especially for ESPhome. With this excellent code I started to build something like the CAN bus component for the LIN.
I can write assemblercode a lot easier than latest C++. So I would like to ask if you could help out with a code review for a generic component? A generic LIN would be a dream as tons off cheap hardwre from scrapped cars would be available for esphome like sensors, shunts, motors, pumps, fans ....
you can find my repo here: https://github.com/swifty99/linbus
not in the best state yet, steep learning python and c++ at the same time...
I had a generic driver in mind when writing this, but I don't have access to any Lin devices. The current state has some Truma specifics baked into the low level. As the Truma Tin Bus is not 100% compliant with the Lin Bus specs. Also this is (and will stay) a Lin Client piece. I am aware of the challenges a Lin Master implementation must solve.
yes, the truma app on top of a generix LIN in Esphome would be no fun, and seems to work anyway. I would be happy, if you could look over the generic part every now and then. I know to write assembly, C++ ist still very fancy. I have a lot of LIN devices left over from scrapping cars.. I think you live in Berlin? No problem if you like to get some. And these parts are way easier to control, set the right byte and of they go.
