Review on 📺 Bicool 1.3" OLED Display Module - Black/White - 64×128 Resolution - Embedded SH1107 Driver - SPI / I2C Interface - Compatible with Arduino/Raspberry Pi/STM32 by Aaron Lewis

I'm fairly new to the world of crafting so my review will be from a position with little experience. comes with documentation which is a little frustrating but seems normal for the various breakouts I've played with. As you can see, in the end everything worked out for me on the Arduino nano. What I did: I searched for the driver chip (GC9A01) on github and found Arduino_GFX from moononournation. The Arduino IDE found this normal in the library manager so I didn't have to do it manually. Then: HelloWorld downloaded from the examples. The line starting with "Arduino_GFX" has been changed to " (I wasn't sure how that would work.) The GFX library seems to be poorly documented, so code review and trial and error are required to do what you want. Maybe I just didn't find it... There is no central pixel. If you want a circle along the outside edge using the Arduino_GFX library
