Detailed Description

API to send console messages to the ARM9 from the ARM7.

You need to setup this console by calling consoleArm7Setup() on the ARM9.

Function Documentation

consoleIsSetup()

bool consoleIsSetup

(

void

)

Checks if the console has been setup by the ARM9 or not.

Returns

Returns true if the console is setup, false if not.

consolePrintChar()

int consolePrintChar

(

char

c

)

Adds a character to the ring buffer to be printed.

If the buffer is full, this function will send a flush command to the ARM9 and it will wait until there is space to add a new character.

Parameters

c	Character to be printed.

Returns

It returns 0 on success, or an error code if the console hasn't been initialized.

consolePrintf()

int consolePrintf	(	const char *	fmt,
			...
	)

It adds a formatted string to the buffer.

This version is a super minimalistic printf(). Supported flags:

• c: Character.
• $d: Signed decimal 32-bit integer.
• s: String.
• $u: Unsigned decimal 32-bit integer.
• x: Hexadecimal 32-bit integer.

Parameters

fmt	Formatted string.

Returns

It returns 0 on success, -1 if there are unsuported flags.

consolePrintNumUnsigned()

void consolePrintNumUnsigned	(	uint32_t	num,
		uint32_t	base
	)

Adds an unsigned integer to the ring buffer to be printed.

Parameters

num	Unsigned integer to be printed.
base	Base of the number to be used (normally 10 or 16, max is 16).

consolePuts()

void consolePuts

(

const char *

str

)

Adds a string to the ring buffer to be printed.

Parameters

str	String to be printed.

consoleVprintf()

int consoleVprintf	(	const char *	fmt,
		va_list	args
	)

It adds a formatted string to the buffer.

Parameters

fmt	Formatted string.
args	va_list object.

Returns

It returns 0 on success, -1 if there are unsuported flags.
