If you need for your ESP Projects a LCD Display, might worth to take in consideration also ST7032i.
It has I2C compatible interface, so less data pins used.

A driver with basic functions implemented few days ago and it’s working nice & stable.

These solution is for Lui uploader.
I’m using NodeMCU 1.0 and try with original ST7032 library with those 2 changes.
Line 32 //#include <avr/pgmspace.h>
Line 91 Wire.begin(0, 2); //set SDA & SCL pin

After that I get C and Data signal on LCD display, but (during writing string) data byte is always the same and 1 bit is overwrite from display, so SDA is during one of the CLK periode at aprox. 2V.
There is nothing on display
