OLED Fonts

Nim wrapper for OLED font data utilities.

Provides various bitmap fonts for use with OLED displays (SSD130x family). These fonts are pre-rendered ASCII character sets optimized for small displays.

Available Fonts:

Font_4x6 - Tiny font (4x6 pixels per character)
Font_4x8 - Small font (4x8 pixels)
Font_5x8 - Small font (5x8 pixels)
Font_6x7 - Medium small font (6x7 pixels)
Font_6x8 - Medium font (6x8 pixels)
Font_7x10 - Medium font (7x10 pixels)
Font_11x18 - Large font (11x18 pixels)
Font_16x26 - Extra large font (16x26 pixels)

Example:

import nimphea/src/nimphea
import nimphea/src/dev/oled
import nimphea/src/util/oled_fonts

var display: OledDisplay128x64I2c
# ... initialize display ...

# Use different font sizes
display.setFont(Font_7x10)
display.writeString("Medium", Font_7x10, true)

display.setFont(Font_16x26)
display.writeString("Large", Font_16x26, true)

Note: These fonts are migrated from the stm32-ssd1306 library by afiskon.
