In this tutorial, we will see how to display the images/icons on 128x64 Monochrome GLCD. To do this we need images of 128x64 pixels, if not we have to crop/resize the higher resolution images. This can be done using photoshop or some other photo editors. We will be using the windows built in tool PAINT.

Image Resize

Lets take a high resolution image and crop it to 128x64 and then generate the bitmap. IPL.png

Do the setting as shown in the image. Glcd Logo 5.png

Click on FILE->Save Output and save the output file as logo.txt Glcd Logo 6.png

The bitmap for the image will be saved in an array as shown in the below image. Glcd Logo 7.PNG

Use this array in your code for displaying the image/logo on the GLCD.


Below is the complete code with the bit map array.
Check glcd.h file for pin connection.
