- Tue Aug 04, 2015 10:23 am #25006 Hello,

I've been trying to setup a screen on the ESP8266 but without success (ESP12/nodemcu 0.9 + LCD 1602/I2C + LiquidCrystal library)

I don't know which pin to use for the I2C communication on the ESP12 (which PIN are SDA and SCK).

Has anyone some experience with this LCD1602 and the ESP12 with the Arduino IDE ?

Or which screen are using for your projects ?

See http://playground.arduino.cc/Code/PCD8544 for some basic code to start with.

- Mon Jan 25, 2016 1:58 pm #39667 I have a 1602 with I2C module and I am able to make it work with my Arduino Uno and Mega just fine using LiquidCrystal_i2c library. I would like to use it with NodeMCU in Arduino environment. The major question is the same as the original poster's, which pins should I connect SDA and SCL to? Also what, if any, modifications need to be done to the LiquidCrystal_i2c library or Wire library etc. Could you please shed some light on it?
