Detailed Description

ARGOS Low Data Rate HDLC decoder.

Constructor & Destructor Documentation

◆ argos_ldr_decoder()

gr::satnogs::argos_ldr_decoder::argos_ldr_decoder ( bool  crc_check = true,
size_t  max_frame_len = 64 
)

/** The decoder take as input a quadrature demodulated bit stream. Each byte should contains only one bit of information at the LSB.

propagated

Parameters
max_frame_lenthe maximum allowed frame length
Returns
a shared pointer of the decoder instance

Member Function Documentation

◆ decode()

decoder_status_t gr::satnogs::argos_ldr_decoder::decode ( const void *  in,
int  nitems 
)
virtual

Decodes a buffer of input items contained in the in buffer. This method is called continuously by the frame_decoder. Based on the returned status data, the frame_decoder() instructs properly the GNU Radio scheduler and/or propagates decoded data.

As the number of input items may not enough to decode a frame, each decoder should keep internal state, so decoding can be accomplished after an arbitrary number of calls to this method

Parameters
inthe input items
nitemsthe number of input items contained in the in buffer
Returns
the status of the decoder after the call of this method. For more information refer to decoder_status()

Implements gr::satnogs::decoder.

◆ make()

static decoder::decoder_sptr gr::satnogs::argos_ldr_decoder::make ( bool  crc_check = true,
size_t  max_frame_len = 64 
)
static

The decoder take as input a quadrature demodulated bit stream. Each byte should contains only one bit of information at the LSB.

propagated

Parameters
max_frame_lenthe maximum allowed frame length
Returns
a shared pointer of the decoder instance

◆ reset()

void gr::satnogs::argos_ldr_decoder::reset ( )
virtual

Resets the internal state of the decoder to the initial defaults

Implements gr::satnogs::decoder.
