Struct libdvb::fe::FeDevice[−][src]

pub struct FeDevice { /* fields omitted */ }

A reference to the frontend device and device information

Implementations

impl FeDevice[src]

pub fn clear(&self) -> Result<()>[src]

Clears frontend settings and event queue

pub fn open_ro(adapter: u32, device: u32) -> Result<FeDevice>[src]

Attempts to open frontend device in read-only mode

pub fn open_rw(adapter: u32, device: u32) -> Result<FeDevice>[src]

Attempts to open frontend device in read-write mode

pub fn set_properties(&self, cmdseq: &[DtvProperty]) -> Result<()>[src]

Sets properties on frontend device

pub fn get_properties(&self, cmdseq: &mut [DtvProperty]) -> Result<()>[src]

Gets properties from frontend device

pub fn get_event(&self, event: &mut FeEvent) -> Result<()>[src]

Returns a frontend events if available

pub fn read_status(&self) -> Result<u32>[src]

Returns frontend status

pub fn read_signal_strength(&self) -> Result<u16>[src]

Reads and returns a signal strength relative value (DVBv3 API)

pub fn read_snr(&self) -> Result<u16>[src]

Reads and returns a signal-to-noise ratio, relative value (DVBv3 API)

pub fn read_ber(&self) -> Result<u32>[src]

Reads and returns a bit error counter (DVBv3 API)

pub fn read_unc(&self) -> Result<u32>[src]

Reads and returns an uncorrected blocks counter (DVBv3 API)

pub fn set_tone(&self, value: u32) -> Result<()>[src]

Turns on/off generation of the continuous 22kHz tone

allowed value’s:

  • SEC_TONE_ON - turn 22kHz on
  • SEC_TONE_OFF - turn 22kHz off

pub fn set_voltage(&self, value: u32) -> Result<()>[src]

Sets the DC voltage level for LNB

allowed value’s:

  • SEC_VOLTAGE_13 for 13V
  • SEC_VOLTAGE_18 for 18V
  • SEC_VOLTAGE_OFF turns LNB power supply off

Different power levels used to select internal antennas for different polarizations:

  • 13V:
    • Vertical in linear LNB
    • Right in circular LNB
  • 18V:
    • Horizontal in linear LNB
    • Left in circular LNB
  • OFF is needed with external power supply, for example to use same LNB with several receivers.

pub fn diseqc_master_cmd(&self, msg: &[u8]) -> Result<()>[src]

Sets DiSEqC master command

msg is a message no more 6 bytes length

Example DiSEqC commited command:

[0xE0, 0x10, 0x38, 0xF0 | value]
  • byte 1 is a framing (master command without response)
  • byte 2 is an address (any LNB)
  • byte 3 is a command (commited)
  • last 4 bits of byte 4 is:
    • xx00 - switch input
    • 00x0 - bit is set on SEC_VOLTAGE_18
    • 000x - bit is set on SEC_TONE_ON

pub fn get_api_version(&self) -> u16[src]

Returns the current API version major - first byte minor - second byte
