Functions

HIDAPI char hid_parse_key (u8 modifier, u8 usage_id)
 Parses a HID key combination into an ASCII character.

Variables

HIDAPI const char HID_TO_ASCII_LOWER [HID_USAGE_MAX]
 Lookup table for Lowercase characters (No Shift). Maps HID Usage IDs to their ASCII representation.
HIDAPI const char HID_TO_ASCII_UPPER [HID_USAGE_MAX]
 Lookup table for Uppercase characters (Shift Held). Maps HID Usage IDs to their ASCII representation when Shift is active.

Detailed Description

USB HID Usage Tables and ASCII conversion logic.

This header contains the standard USB HID Usage IDs for keyboards (Page 0x07) and lookup tables to convert these Scancodes into ASCII characters based on modifier states (Shift).

Note
This file uses static definitions for tables to allow header-only inclusion.
