@brief Interface of RMT encoder

Fields§

§encode: Option<unsafe extern "C" fn(_: *mut rmt_encoder_t, _: *mut rmt_drv_channel_t, _: *const c_void, _: usize, _: *mut u32) -> usize>

@brief Encode the user data into RMT symbols and write into RMT memory

@note The encoding function will also be called from an ISR context, thus the function must not call any blocking API. @note It’s recommended to put this function implementation in the IRAM, to achieve a high performance and less interrupt latency.

@param[in] encoder Encoder handle @param[in] tx_channel RMT TX channel handle, returned from rmt_new_tx_channel() @param[in] primary_data App data to be encoded into RMT symbols @param[in] data_size Size of primary_data, in bytes @param[out] ret_state Returned current encoder’s state @return Number of RMT symbols that the primary data has been encoded into

§reset: Option<unsafe extern "C" fn(_: *mut rmt_encoder_t) -> i32>

@brief Reset encoding state

@param[in] encoder Encoder handle @return - ESP_OK: reset encoder successfully - ESP_FAIL: reset encoder failed

§del: Option<unsafe extern "C" fn(_: *mut rmt_encoder_t) -> i32>

@brief Delete encoder object

@param[in] encoder Encoder handle @return - ESP_OK: delete encoder successfully - ESP_FAIL: delete encoder failed
