I made an ESP8266 fetch the time from the internet and display it on a 0.96'' oled through i2c. It works fine with my nodeMCU, but does not display anything on the screen when I switch to an esp-m3 (esp8285 based board). It still fetches the time and prints it to the serial monitor, and I have confirmed that power is getting to the oled, so I'm a bit lost as to why the screen is not turning on. Does it have something to do with the digital pins I am using? I really don't know much about i2c and how it could go wrong.
