Public Attributes | |
| int | bit_rate |
| The bit rate of the modem. Valid values are 2400 and 4800. | |
| get_bit_func_t | get_bit |
| The callback function used to get the next bit to be transmitted. | |
| void * | get_bit_user_data |
| A user specified opaque pointer passed to the get_bit function. | |
| modem_status_func_t | status_handler |
| The callback function used to report modem status changes. | |
| void * | status_user_data |
| A user specified opaque pointer passed to the status function. | |
| float | gain_2400 |
| The gain factor needed to achieve the specified output power at 2400bps. | |
| float | gain_4800 |
| The gain factor needed to achieve the specified output power at 4800bps. | |
| complexf_t | rrc_filter [2 *9] |
| The root raised cosine (RRC) pulse shaping filter buffer. | |
| int | rrc_filter_step |
| Current offset into the RRC pulse shaping filter buffer. | |
| uint32_t | scramble_reg |
| The register for the training and data scrambler. | |
| int | scrambler_pattern_count |
| A counter for the number of consecutive bits of repeating pattern through the scrambler. | |
| int | in_training |
| TRUE if transmitting the training sequence, or shutting down transmission. FALSE if transmitting user data. | |
| int | training_step |
| A counter used to track progress through sending the training sequence. | |
| uint32_t | carrier_phase |
| The current phase of the carrier (i.e. the DDS parameter). | |
| int32_t | carrier_phase_rate |
| The update rate for the phase of the carrier (i.e. the DDS increment). | |
| int | baud_phase |
| The current fractional phase of the baud timing. | |
| int | constellation_state |
| The code number for the current position in the constellation. | |
| get_bit_func_t | current_get_bit |
| The get_bit function in use at any instant. | |
| logging_state_t | logging |
| Error and flow logging control. | |
