Struct Cec

pub struct Cec<const BASE: usize> { /* private fields */ }

HDMI-CEC driver.

Implementations

impl<const BASE: usize> Cec<BASE>

pub unsafe fn new() -> Cec<BASE>

Create a new HDMI CEC driver.

Safety

1. The HDMI CEC source clock must be enabled.
2. The HDMI CEC pin must be configured.
3. The HDMI CEC peripheral should be reset before.
4. The HDMI CEC registers provided by the PAC should be dropped.
5. The generic BASE parameter must be correct or bad things will happen.

Panics

Panics if reading CFGR does not return the value written. This occurs when the HDMI CEC peripheral clocks are not configured correctly.

Example

use stm32_cec::Cec;

// device specific setup occurs here
// ...

// valid address for the STM32H7
let mut cec: Cec<0x40006C00> = unsafe { Cec::<0x40006C00>::new() };

pub fn set_standby(&mut self, src: LogiAddr, dst: LogiAddr) -> Result<(), u32>

Power off devices.

Example

Turn everything off.

use stm32_cec::{Cec, LogiAddr};

let mut cec = unsafe { stm32_cec::Cec::<0x40006C00>::new() };
cec.set_standby(LogiAddr::Broadcast, LogiAddr::Broadcast)?;

pub fn set_image_view_on( &mut self, src: LogiAddr, dst: LogiAddr, ) -> Result<(), u32>

Power on the TV.

Example

Turn everything on.

use stm32_cec::{Cec, LogiAddr};

let mut cec = unsafe { stm32_cec::Cec::<0x40006C00>::new() };
cec.set_image_view_on(LogiAddr::Broadcast, LogiAddr::Broadcast)?;
