I looked at your article on using a NodeMCU with LCU using I2C and I can’t get it to work nor understand it. I’m able to connect the I2C/LCD to an Arduino UNO and it works fine but SCL and SDA are connected to address pins and your article connects to digital pins. How is it able to get an address from data pins? Can you please elaborate? Am I missing something?
UPDATE: I figured it out. The I2cScanner doesn’t work for ESP8266. I found another here:
The address was 0x27.
