Struct SyncManager 

pub struct SyncManager<'d, const N: usize> { /* private fields */ }

In some real-time control applications (e.g., to make two robotic arms move simultaneously), you do not want any time drift between different channels. The RMT driver can help to manage this by creating a so-called Sync Manager.

The procedure of RMT sync transmission is shown here.

Implementations

impl<'d, const N: usize> SyncManager<'d, N>

pub fn new(channels: [TxChannelDriver<'d>; N]) -> Result<Self, EspError>

Create a synchronization manager for multiple TX channels, so that the managed channel can start transmitting at the same time.

Note

All the channels managed by the sync manager should be enabled before creating the sync manager.

Errors

• ESP_ERR_INVALID_ARG: Create sync manager failed because of invalid argument
• ESP_ERR_NOT_SUPPORTED: Create sync manager failed because it is not supported by hardware
• ESP_ERR_INVALID_STATE: Create sync manager failed because not all channels are enabled
• ESP_ERR_NO_MEM: Create sync manager failed because out of memory
• ESP_ERR_NOT_FOUND: Create sync manager failed because all sync controllers are used up and no more free one
• ESP_FAIL: Create sync manager failed because of other error

pub fn reset(&mut self) -> Result<(), EspError>

Reset synchronization manager.

Errors

• ESP_ERR_INVALID_ARG: Reset the synchronization manager failed because of invalid argument
• ESP_FAIL: Reset the synchronization manager failed because of other error

pub fn channels_mut(&mut self) -> &mut [TxChannelDriver<'d>; N]

Returns a mutable reference to the managed TX channels.

pub fn channels(&self) -> &[TxChannelDriver<'d>; N]

Returns a reference to the managed TX channels.

pub fn into_channels(self) -> [TxChannelDriver<'d>; N]

Consumes the sync manager and returns the managed TX channels.

Trait Implementations

impl<'d, const N: usize> Drop for SyncManager<'d, N>

fn drop(&mut self)

Executes the destructor for this type.
