Detailed Description

Font size and text rendering configuration.

Compile-time configuration system for text resources, controlled by resource/config.h macros.

Types Documentation

enum Ascii_Font_Size

Enumerator	Value	Description
NO_ASCII_SIZE		Sentinel value indicating no valid font size available.

Enumeration of available ASCII font sizes.

Specifies available monospace font sizes for text rendering. Enabled fonts are determined at compile-time via:

• ENABLE_ASCII_6x8_SOURCES (6x8 pixel font)
• ENABLE_ASCII_8x16_SOURCES (8x16 pixel font) Current implementation supports:

6x8: 6 pixels wide x 8 pixels tall per character

• 8x16: 8 pixels wide x 16 pixels tall per character To add more fonts:

• Provide font bitmap data source

• Implement __select_from_ascii_font_size() for new size
• Add enable macro in resource/config.h__select_from_ascii_font_size()

__fetch_font_size()

enum Unicode_Font_Size

Enumerator	Value	Description
Unicode_16x16		16x16 pixel Unicode font - for CJK and other wide characters

Enumeration of available Unicode font sizes.

See: Ascii_Font_Size

Note: Unicode support requires:

• Additional memory for character data (Chinese, Japanese, etc.)
• Larger display for readable text
• Future implementation phase

Specifies Unicode font sizes for international character support. Currently supports 16x16 pixel Unicode characters.
