Hi Andrius,
Thank you very much.
I haven't testes i2c yet, but I will do it soon. I am very curious!
I just went again through the code and I see no documentation yet.
Please understand that documentation is a very important (I would say
critical) art of your programming activity. Without documentation your
code is not as valuable as it could be! Please document serial and i2c
properly before continuing developing code.
It is not only necessary to add comments to your code, but also (and
this is necessary if you want your project to be released publicly, or
ever migrate to core) add documentation for the user in the help
string.
Do not underestimate the time and difficulty of documenting your
functions. A professor of mine used to say documenting is about 30% of
the time of a project.
Keep up the good job.
