#Simple Font And Image generator

Simple scripts for generating bit fonts for STM32, AVR, Arduino or other MCU, game and etc.

#How to use Font Generator

  1. Install python 3.4 or newer

  2. Install PILLOW:

pip install Pillow

  1. Select font and place it in the folder with scripts

  2. Edit config.py

  3. run GenerateFontBitmap.py, it will be create and open image with name as bitmap_png value:

python GenerateFontBitmap.py
  1. Check and edit bitmap_png. Regenerate font if thats required.

Check this:

  • All chars must be in their cells
  • If cell is blue, that means it's height more then default and it was offseted up.
  • Check if white pixels isn't on cell outline. Like this alt text

If something wrong you can change anything in any image editor.

Good font must be look like:

  1. Generate code with:
python BitmapFontToCode.py
  1. DONE! Use this font wherever you want! For example:

#How to use Image generator:

  1. Edit "png" value in ImageToCode.py. That is a path to image.

  2. Generate code and file:

python ImageToCode.py

You can find usage of generated code here: https://github.com/SL-RU/stm32libs/blob/master/HAL/ssd1306/ssd1306.c in function void ssd1306_image(uint8_t *img, uint8_t x, uint8_t y)

#How to use font with my ssd1306 stm32 library:

  1. Add defenition in fonts.h

  2. Add generated font data to fonts.c and set params

const uint8_t customfont[] = {
  //output_file text
};
FontDef_t custom_font = {
	width,
	height,
	byte width, //in the end of output BitmapFontToCode.py
	customfont
};

Good luck!
