Hi, which OLED are you using? Is it Grove 1305? Have you checked your OLED separately? With a simple Arduino UNO?
There is nothing wrong with the upstairs way of troubleshooting. From experience, this OLED screen is very fragile and we suggest trying to use the Arduino UNO to test if the screen is working properly first. We look forward to hearing from you.
