Detailed Description

Client for Hellschreiber transmissions.

Constructor & Destructor Documentation

HellClient() [1/2]

HellClient::HellClient ( PhysicalLayer *  phy )

explicit

Constructor for 2-FSK mode.

Parameters

phy	Pointer to the wireless module providing PhysicalLayer communication.

HellClient() [2/2]

HellClient::HellClient ( AFSKClient *  audio )

explicit

Constructor for AFSK mode.

Parameters

audio

Pointer to the AFSK instance providing audio.

Member Function Documentation

begin()

int16_t HellClient::begin	(	float	base,
		float	rate = 122.5
	)

Initialization method.

Parameters

base	Base RF frequency to be used in MHz (in 2-FSK mode), or the tone frequency in Hz (in AFSK mode).
rate	Baud rate to be used during transmission. Defaults to 122.5 ("Feld Hell")

printGlyph()

size_t HellClient::printGlyph

(

uint8_t *

buff

)

Method to "print" a buffer of pixels, this is exposed to allow users to send custom characters.

Parameters

buff	Buffer of pixels to send, in a 7x7 pixel array.

Returns

Always returns the number of printed glyphs (1).

setInversion()

void HellClient::setInversion

(

bool

invert

)

Invert text color.

Parameters

invert

Whether to enable color inversion (white text on black background), or not (black text on white background)
