Hey guys, I got this cheap oled screen from china. My photon just arrived and so I decided to help our local Hacklab (maker space) in creating an rfid reader with this oled screen. I’ve seen a few posts on the subject but am still not sure which library to use with this display? There is an Adafru…

You have clicked on the library, hit the INCLUDE IN PROJECT button and then selected the target project to import the library into? If you have done that right, your project should look like this [image] You actually need to have the system “copy” the library references into your project. The #i…

@synteny , welcome to Photown! :stuck_out_tongue: If you look near the bottom of this thread, you'll find posts from someone with the exact same display: [image] Adafruit SSD1306 Library [Ported] Libraries UPDATE: Adafruit_SSD1306 Ported by @peekay123 below! https://commu…

I just tested one of these yesterday. I got mine from Amazon: Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more I think its the same product as yours. The post from peekay123 has the wiring instructions. Basically the addr…

@Carsten4207 , thanks for the info. You rock! :wink:

@Carsten4207 +1 on rocking, @peekay123 thanks for the info and the welcome. Man you guys were quick. I can’t wait to get home tonight and see what i can get done. I’ll ping back after with yay or nay and anything added i can add. Also trying to figure out how to dim some led strip (5050 led strip)…

Hi! What is it you connect to the reset pin when there is only 4 pins on the display? :thinking:

That depends on what these pins are :wink: But assuming they are Vcc, GND, Data & Clock, you just forget about reset (passing a dummy value e.g. -1).

Do youhave a pinout on how its connected to your board? I think i’m trying to do the same thing but not sure what pins to use.

Hi, I’ve tried your code. But it ends up to an error. /firmware/wiring/src/spark_wiring_random.cpp:5: multiple definition of `random(int)’ Besides, there is no [#include “Adafruit_SSD1306/Adafruit_SSD1306.h”] in the library; therefore, I change it to #include “Adafruit_SSD1306.h” from particle l…

You need to comment out the extra definition of random() in the example code. Usually the full error log provodes you with the place of all conflicting definitions.

Hi, It looks from this post that I could use SCL = A5, SDA = A4, instead of D0/D1? If so, how do I tell the software to use those pins instead? Thanks, Austin
