Hello,
my apologies for that. Anyway i put the board model in the first post from the beginning, but not the library, sorry again por that. I was doubt about the same question.... write in the same post or open a new and i decide to open a new because i think it's different issue.
Anyway i edit the post with all the info, now you can see the display in the full code (2,13" B/W Waveshare) and yes, i have resistors for asure 3.3v.
Thanks for your understanding and help. I see all libraries info from the beginning and i don't understand anything about this issue, anyway i will check it again, meanwhile if you want/can add some info with my full edited information i apreciate a lot
I will check your suggestions.
Thanks for your attention.
Regards.
