How to display Custom Graphics with Arduino
25
07.02.2017
In this video we take a look at creating a custom bitmap graphic and displaying on any of the common displays available for the Arduino (SPI & I2C OLEDs, and the Nokia 5110).
First we create the graphic in a program of our choice ( We used Photoshop), after creating your custom graphic, you must change the mode to 2 color bitmap, and save the file as a BMP file. Keep in mind the file must be the final size before saving as the you will be unable to change the size later. In our case the clock is 32x32 pixels.
Now we have to convert the bitmap to hexidecimal bytes. This is done with the LCD Assistant program. You can download it free here: http://en.radzio.dxp.pl/bitmap_converter/
After loading the file, set the program for horizontal, and click save. Choose a file name and click ok. Now open the file LCD Assistant created and copy the contents to your sketch. Now it's just a matter of calling the display.drawbitmap() function.
All of my sketches are available here: https://www.dropbox.com/sh/m6c40pu99fqxb5b/AAD1Gzn6F4Hy8v9RrTZSxQyHa?dl=0
