1.8 Inch 128x64 ST7565 Serial LCD Display With Backlight (HCMODU0246)

[admin]

This 1.8” LCD monochrome graphical display has a resolution of 128x64 pixels with pixel colour being black on a white backlit background.

For interfacing via a microcontroller the display uses an ST7565 serial controller consisting of a single clock and data pin for communication plus chip select and data/command pins for control. These pins plus power and reset are all available via a soldered 8 pin 0.1” header.

For Arduino users this module is supported by our HCDisplay library. See bottom of this post for more information.


NOTES:

This is a 3.3V display. If using with a 5V microcontroller level shifters must be used.

1. /* File:    HCDisplay_Hello_World.ino
2.  * Version: 1.0
3.  *
4.  * This is a simple sketch to demonstrate how to print text at specified locations
5.  * on the display. The sketch also shows how to change font style and
6.  * foreground/background colour.
7.  *
8.  * IMPORTANT: To use this sketch you must first select your display type
9.  * by opening up the Options.txt file (found the HCDisplay library folder)
10.  * in a text editor and uncommenting the line:
11.  *
12.  * #define ST7565

Very pleased with this display. Ideally suited to low power applications -
Screen is clearly visible in daylight even without backlight reducing power consumption to less that 1mA.
HCDisplay library simple to use with this device. Thanks
