I'm trying to connect and LK402-12 module to a PIC16F877 module via the I2C bus. I read the manual but I don't see to much data about the slave address of the LCD module. In a I2C explicative paragraph I read: "it would be 8Ah to write and 8Bh to read". But, it is?

This module don't have jumpers (like LK204-25) to set a slave address.

Thanks in advance.

This program will allow you to change the I2C address, it's located in the download section

and you are correct regarding reading and writing.
