Macros
#define	CONSOLE_HW_KEYS_PER_PASS   64u
	Characters taken in one pass: a pasted line of PAGE_CONSOLE_LINE_MAX takes 3 passes at most.

Functions
void	console_hw_init (const link_dev_t *dev)
	The console on the pages of dev.
void	console_hw_pass (void)
	Once a pass: the characters that came, the report of a HITEC operation that has ended, and as much output as the USB transmit buffer has room for now, a line cut where the room ends and its rest first in the next pass.
void	console_hw_say (const char *fmt,...)
	A line for the USB serial port, formatted as printf() formats, through the console's output: it leaves after the lines said before it and never inside one, and saying it does not wait for the host.

Variables
static page_console_t	s_console
static char	s_out [PAGE_CONSOLE_OUT_LINE *2u]
	The output of one pass, off the main loop's stack.

Function Documentation

console_hw_init()

void console_hw_init

(

const link_dev_t *

dev

)

The console on the pages of dev.

After link_dev_init().

Parameters

dev	The link device whose pages the console serves.

console_hw_pass()

void console_hw_pass

(

void

)

Once a pass: the characters that came, the report of a HITEC operation that has ended, and as much output as the USB transmit buffer has room for now, a line cut where the room ends and its rest first in the next pass.

A line of any length leaves. Never waits for the host: a pass writes no more than the buffer has free, and a host that stops reading leaves the output in the console's buffer.

console_hw_say()

void console_hw_say	(	const char *	fmt,
			... )

A line for the USB serial port, formatted as printf() formats, through the console's output: it leaves after the lines said before it and never inside one, and saying it does not wait for the host.

Dropped while no host has the port open, as printf() drops it.

Parameters

fmt	printf() format string.
...	Arguments for the format string.
