Having issues with a snowy display on my ssd1306 128x64 breakout board
Version Info Micropython:
(sysname='esp32', nodename='esp32', release='1.17.0', version='v1.17 on 2021-09-02', machine='ESP32 module with ESP32')
1. Firstly, when I tried to install the "micropython-ssd1306" (v 0.3 latest stable version) from the plug-in manager in Thonny v3.3.13 I got the following error from PyPi:

I am not sure what's going on there but I do have issues using PIP at the command prompt and have attempted to solve that by fixing path problems, but to no avail.
I am thinking this is the most viable version, and looks like Adafruit only supports Circuit Python now, but unable to find a repository I went out and tried random copy / paste sessions from online tutorials and saving ssd1306.py to the board, which led me to a version that at least would not cause Traceback errors.
2. Second issue was with i2c - I believe SoftI2C should be used now? I didn't capture the Traceback I was getting with I2C, but I get none with SoftI2C and can scan and find address 60 dec... so the comms seem good.
I read an obscure post about a reset pin needing to be triggered after power up some ssd1306 boards, but there is no exposed reset pin on my breakout board.
I have tried to use various combinations of other pins on the ESP32 to no avail, and again, whichever pins I use I can scan.
Not sure what to do now - Are pullup resistors required? Can anyone else think of what else I can check for?

Re: SSD1306 i2c static or snowy display
Nevermind!
…was using the wrong driver. Mine is an sh1106 display, not an ssd1306
If anyone else runs into this the correct driver is located here:
