I have my nodemcu v0.9 up and running reading my woodstove internal temperture from SPI (thermocouple). Now I would to add a local display at the stove. I just purchased a Digole OLED which can be uart/spi or I2C. What should I choose ? any advice or experience is greatly appreciated. Final goal would be a dial gauge display.

Ok Thanks Bob...my screen is a Digole. I will start testing I2C with their samples
