@brief Transmit data by RMT TX channel

@note This function constructs a transaction descriptor then pushes to a queue. The transaction will not start immediately if there’s another one under processing. Based on the setting of rmt_transmit_config_t::queue_nonblocking, if there’re too many transactions pending in the queue, this function can block until it has free slot, otherwise just return quickly. @note The data to be transmitted will be encoded into RMT symbols by the specific encoder.

@param[in] tx_channel RMT TX channel that created by rmt_new_tx_channel() @param[in] encoder RMT encoder that created by various factory APIs like rmt_new_bytes_encoder() @param[in] payload The raw data to be encoded into RMT symbols @param[in] payload_bytes Size of the payload in bytes @param[in] config Transmission specific configuration @return - ESP_OK: Transmit data successfully - ESP_ERR_INVALID_ARG: Transmit data failed because of invalid argument - ESP_ERR_INVALID_STATE: Transmit data failed because channel is not enabled - ESP_ERR_NOT_SUPPORTED: Transmit data failed because some feature is not supported by hardware, e.g. unsupported loop count - ESP_FAIL: Transmit data failed because of other error
