Hey All...noobie here,
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.

Jeff, I would use I2C because it uses less pins and the UART is used for programming unless you use OTA programming. I have successfully used I2C to run an OLED using the esp/Arduino IDE

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