Hi!
They say there is nothing worse than a free gift as you end up paying for it multiple times.
Well I say it´s even worse when you decide to do this to yourself.
So I was browsing ebay the other day and I decided that my next little project would have an oled display, nothing serious just to torment myself for fun and gather some exp..
I came across this nice little thing:
https://www.ebay.com/itm/0-91-0-91in-White-Blue-OLED-Module-Display-IIC-Interface-128x32-SSD1306/142831922310?ssPageName=STRK%3AMEBIDX%3AIT&var=441833372791&_trksid=p2057872.m2749.l2649Everything seems to have something like that inside nowadays, from toaster to soldering iron, so why not kill some time trying to program it, find what makes it tick and so on and so forth.
From what I gathered it was using a SSD1306 chip inside, or at least a knock-off controller like that one, made from pure chinesium. Good stuff! Good times!
Since most of the blogs documenting it and "ready to use" modules were either configured as SPI or I2C, I said great, I really don´t like coding for I2C but I love SPI, so that´s great!
After some weeks product arrives and I try to find a datasheet! (BTW I am still looking for one so if anyone has a link, please feel free to help :-) )
And what I find out leaves me so dumb-fu€ked that I try to let out my frustration in this post.
There are 2 versions of it. One 14pin and one 15pin... 15pin version supports both protocols, 14pin version is only i2c and of course I got this one.
Why? How can this be any cheaper in the end? It is probably a question of which clone came first but still... why?
You go through the effort to clone the shit! Why? Just why...
I kinda don´t what to wait more for me to play around, then again, I feel kinda bored trying to do my own PCBs, so I might as well design and order...
I´ll see, whether or not I force myself to go through writing a proper i2c library or order the also SPI enabled part. I know the adafruit library exists, what did I tell you earlier though?
So well... it´s one thing being careful of what you order and another this being true evil...
Best Regards,
Lefteris
