Online tool to convert bitmap to hex codes for Arduino Graphic LCD 84x48 with PCD8544 controller Nokia 5110

Here is a simple tool to convert bitmap images of 84 pixel wide and 48 pixel height to hex codes for using with arduino's and in other avr projects (may work on other images as well, but no guarantee).

Graphic LCD with PCD8544 controllers (esp Nokia lcd, 3310, 5110 etc should work)

If looking for creating hex and bin matrix for ordinary led matrix using click, the tool can be accessed at the link here  LED MATRIX

  1. Upload the image using file selector (scroll down) 
  2. Copy the hex codes in to your arduino sketch
  3. Example sketch and wiring can be seen at Sparkfun
  4. replace the array name from xkcdSandwich to bitmapArray (in the example)
  5. Upload the sketch
To create the bitmap you can use paint or any other tool and set image size 84X48

Example image, test by save as and then  loading in the tool
This can also be done online (search: Online paint/bitmap editor)

Use the button below to choose a file
