No problem. Actually I did google it like this "int8_t arduino". I only found examples that were not that great (I didn't understand anything). At least in the first 20 searches. I googled "int8_t" just now and there are a few info concerning int8_t in C/C++.
I will see if I understand what int8_t means.
Thank you!
PS: What I know of C/C++ comes from learning arduino. So I am trying to avoid as much as possible info that is for c/c++ and stick to proper libraries. (In this case I would say it is a crappy library.) I am not a C/C++ programmer unfortunately.
