Struct embassy_stm32::can::CanConfig

pub struct CanConfig<'a> { /* private fields */ }

Configuration proxy returned by Can::modify_config.

Implementations

impl CanConfig<'_>

pub fn set_bit_timing(self, bt: NominalBitTiming) -> Self

Configures the bit timings.

You can use http://www.bittiming.can-wiki.info/ to calculate the btr parameter. Enter parameters as follows:

• Clock Rate: The input clock speed to the CAN peripheral (not the CPU clock speed). This is the clock rate of the peripheral bus the CAN peripheral is attached to (eg. APB1).
• Sample Point: Should normally be left at the default value of 87.5%.
• SJW: Should normally be left at the default value of 1.

Then copy the CAN_BUS_TIME register value from the table and pass it as the btr parameter to this method.

pub fn set_bitrate(self, bitrate: u32) -> Self

Configure the CAN bit rate.

This is a helper that internally calls set_bit_timing()Self::set_bit_timing.

pub fn set_loopback(self, enabled: bool) -> Self

Enables or disables loopback mode: Internally connects the TX and RX signals together.

pub fn set_silent(self, enabled: bool) -> Self

Enables or disables silent mode: Disconnects the TX signal from the pin.

pub fn set_automatic_retransmit(self, enabled: bool) -> Self

Enables or disables automatic retransmission of frames.

If this is enabled, the CAN peripheral will automatically try to retransmit each frame until it can be sent. Otherwise, it will try only once to send each frame.

Automatic retransmission is enabled by default.
