The module also has a readily available library for Arduino which makes it ideal even for novice programmers. It communicates through SPI protocol and hence does not require more pins. The module comes with the PCD8544 interface IC which makes this module easy to use with low-level microcontrollers. All this is possible because of its (84×48) monochrome pixels. So it is capable of displaying alphanumeric characters, draw lines and other shapes and even displays a bitmap image.

This is the input pin (MOSI) through which serial instructions are sentĪll SPI modules require a common clock, this clock source is supplied to this pin This pin is used to switch between Data mode (high) and Command mode (low) This pin is made low (0V) to select this particular display when more than one SPI peripherals are used. It an active low pin (resets when 0V is provided) Simply replace their hex codes with the newly generated ones and save the file.This pin resets the module. Load this file into a text editor and scroll down until you see the hex codes for their logo. So, what to do with this data? Well, assuming you are using the Aduino Library for the ST7565 display from Adafruit, the default Adafruit splash screen is stored in the Library file called ST7565.cpp There should be 8 sections (they dont need to be split up, its just easier to check). Then press the Generate button to create the output in a separate window There are no menus just 2 buttons, one to load up a graphics file, and the other to generate the outputĬlick on the Load Graphic button, and load up your bmp graphics file. Once you have created your grahic file, run the BMP-LCD program. The file should be 128 pixels by 64 pixels and 2 colours (black and white) only. The BMP-LCD program doesn't do this, you will need to create a file in your own graphics program.

It requires no installation, just extract it from the zip file, store it somewhere, and run it.įirstly, before you can convert a bmp you need to create one. It's nothing fancy, but it does the job, and is called simply BMP-LCD (not to be confused with the dos program BMP2LCD).
So, as we could not find such a program, we wrote one using Visual Basic Studio 2010. Many created each block of 8x8 pixels upside down.
Whilst there are a few programs out there (free and commercial) we could not find any that created the hex characters in the correct format. When we added these screens to our product lineup we trawled the internet to find a program to convert a 2 colour BMP file into the hex character array that can be used in a program to display the graphic. This is a quick tutorial to show you how you can create a great graphic " Splash Screen" for the ST7565 Graphic LCD Display
