SSD1306 i2c static or snowy display
Posted: Mon Jan 03, 2022 9:43 pm
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?
