HX1230 Graphic LCD Wiring Guide


The HX1230 LCD is a basic graphic LCD screen originally intended for as a cell phone screen. It uses the HX1230 controller to drive a graphic display of 68 rows and 96 columns.

In the guide below we will walk you through the steps to install u8g2 library to Arduino IDE and to interface this LCD to Arduino Uno, ESP32 and STM32F103C8T6 Microcontrollers.


Install u8g2 library

In Arduino IDE, go to Sketch > Include Library, select Manage Libraries


Search for u8g2, select latest version and click on Install button

Sample sketch

In Arduino IDE, go to Files > Examples > U8g2 > full_buffer. Click on GraphicTest
