I have one of these boards and am hoping to get a project going with it soon - so perfect timing on this video - thanks for the tips on setting up the library!

Thank you. I got MELIFE 0.96" OLED ESP-WROOM-32 for ESP32 Display 2.4GHz WiFi Bluetooth Dual Mode Development Board Display for Wemos AP STA from Amazon. It seems to be the same as your WEMOS LOLIN32. There were several reasons this didn't work out of the bag. You cleared up the last one. Nice job. Other's have noticed the pinout on display at 1:23 should say 4 is SDA and 5 is SCL.

This is a fun module. I've had one for some time and have enjoyed the joining of the OLED with the ESP32, sure can make a compact project. Thanks for more info on the board, I'd like to see you make a project with it we could build along with. Thanks for the video!

As usual. Great Vid!!

thank you so much man!!! was having such trouble getting my python code to run properly on this board ( only have experience with adafruit and arduino boards) but your video got me up and running perfectly!! keep making awesome content!!! Thanks!!!!

Very good video!

very interesting... this would be a neat potable module with an analog sensor, then display value with hi/low alarms... thanks...:) 😊

Good morning!

does it still needs RTC module to store clock time?

Is swapping SDA and SCL on line 69 intentional? (address, 5, 4). The other examples appear to be in the order of (address, SDA, SCL).

Thank-you. If its not too much trouble could I ask you to explain why this is necessary?

That is the way this module is wired. It does not work in the reverse.

Interesting. That should stop a lot of head scratching, thanks for the info, very much appreciated.

The documentation on github.com/ThingPulse/esp8266-oled-ssd1306 tells me that the call to the method display of the SSD1306.h / SSD1306Wire.h module should be as following: SSD1306Wire display(ADDRESS, SDA, SDC) Since your demoscript uses this as: SSD1306 display(0x3c, 5, 4); I believe that GPIO 5 would be SDA instead of SCK/SCL and GPIO 4 would be SCK/SCL instead of SDA. So that would mean your writing at the paper at 1:42 would be incorrect. Am I right? I'm quite a newbie to Arduino and related things so correct me if I'm wrong.

Has anyone encountered a problem hooking up an i2C device with this chip I tried with an HMC8553 Compass unit which works fine giving correct values however cant display data on integrated oled. The oled works fine on its own - presumably some i2C conflict with 1306 ?

4 years later, but yes. I could not use any I2C devices simultaneously with the OLED

​@@abdallah_m this module is waste of money

its amazing how much you can get for the price of these modules. thx china :D

A true nightmare. Not documentation nor explaini gs ehat libraries or setup should be made to control this stuff
