basics.h
This is a basic header files with FrostWing specific short forms and basically a good for life header...

hal.h
Header file for Hardware Abstraction Layer -> Source from GoGX OS.

isr.h
Interrupts handler header.

getc_nonblock
int getc_nonblock()
Non-blocking getc from keyboard buffer.

getc
uint8_t getc()
Gets the last pressed char.

process_keyboard
void process_keyboard(InterruptFrame *frame)
This is a function that is ran even when the sleep() function is called.

keyboard_init
void keyboard_init()
Initalizes the RingBuffer to store the characters.

keyboard_flush_buffer
void keyboard_flush_buffer(void)
Clears pending keyboard input so stale keypresses are discarded.

getmodifiers
uint8_t getmodifiers()
Gets the current modifiers (like lshift, rshift, etc.).

handle_char_from_scancode
int handle_char_from_scancode(uint8_t data)
Converts the scancode passed to it to ASCII characters.

scancode_to_char
char scancode_to_char(int scancode, bool uppercase)
Converts the scancode to character.

InterruptFrame
