Select the format shown in the above image and save the file for further process. Step-2: Then you need to save the image in “image_name. Step-1: Decrease the size of the normal image to 128*64 or less, which you can do using any image editing software like MS paint.Īs shown in the picture above, we are setting the width and height of the image to 128*64. Before that you have to make sure that the size of image should not exceed 128*64. To show any image on Graphical LCD, we need HEX code of that image, so here are few steps to convert Image into HEX code. You can go through with the datasheet for detailed information about ST7290 128*64 Graphical LCDĭata Pins (used in parallel 8/4bit communication mode) This graphical LCD has an automatic power on Reset function and can be easily controlled by MCU such as 8051, AVR, ARM, Arduino and Raspberry Pi. Interface communication mode can be switched between parallel and serial using PSB PIN 15. It have wide operating voltage range 2.2v to 5.5v and supports both serial and 8/4-bit parallel communication and comes with ST7290 LCD controller/driver IC.

This Graphical LCD is having low power consumption and also suitable for battery power portable device. We already interfaced GLCD with 8051, today we will interface Graphical LCD with Arduino to display text and images on it. But in Graphical LCDs we have 128*64 which is equal to 8192 dots or 8192/8 = 1024 pixels, so apart from character, we can display any Graphical Image on this GLCD. Ordinary LCD can only print simple text or numbers within a fixed size. The ST9720 Graphical LCD is totally different from the Ordinary LCDs. You can find our entire 16X2 LCD related project by following this link, including interfacing with 8051, AVR, Arduino and many more. We have already used 16X2 LCD in many of our projects and also used TFT LCD with Arduino. There are many types of LCDs used in Electronic Projects.
