Example DVB-S2 tune:
|
|
|
|
```rust
|
|
let cmdseq = vec![
|
|
DtvProperty::new(DTV_DELIVERY_SYSTEM, SYS_DVBS2),
|
|
DtvProperty::new(DTV_FREQUENCY, (11044 - 9750) * 1000),
|
|
DtvProperty::new(DTV_MODULATION, PSK_8),
|
|
DtvProperty::new(DTV_VOLTAGE, SEC_VOLTAGE_13),
|
|
DtvProperty::new(DTV_TONE, SEC_TONE_OFF),
|
|
DtvProperty::new(DTV_INVERSION, INVERSION_AUTO),
|
|
DtvProperty::new(DTV_SYMBOL_RATE, 27500 * 1000),
|
|
DtvProperty::new(DTV_INNER_FEC, FEC_AUTO),
|
|
DtvProperty::new(DTV_PILOT, PILOT_AUTO),
|
|
DtvProperty::new(DTV_ROLLOFF, ROLLOFF_35),
|
|
DtvProperty::new(DTV_TUNE, 0),
|
|
];
|
|
|
|
let fe = FeDevice::open("/dev/dvb/adapter0/frontend0", true)?;
|
|
fe.ioctl_set_property(&mut cmdseq)?;
|
|
```
|
|
|
|
Frontend information:
|
|
|
|
```rust
|
|
let fe = FeDevice::open("/dev/dvb/adapter0/frontend0", false)?;
|
|
println!("{}", &fe);
|
|
```
|
|
|
|
Frontend status:
|
|
|
|
```rust
|
|
let fe = FeDevice::open("/dev/dvb/adapter0/frontend0", false)?;
|
|
let mut status = FeStatus::default();
|
|
status.read(&fe)?;
|
|
println!("{}", &status.display(1));
|
|
```
