When configuring channel in transmit mode, set **tx_config** and the following members of :cpp:type:`rmt_tx_config_t`:
|
||||
|
||||
* Transmit the currently configured data items in a loop - **loop_en**
|
||||
* Enable the RMT carrier signal - **carrier_en**
|
||||
* Frequency of the carrier in Hz - **carrier_freq_hz**
|
||||
* Duty cycle of the carrier signal in percent (%) - **carrier_duty_percent**
|
||||
* Level of the RMT output, when the carrier is applied - **carrier_level**
|
||||
* Enable the RMT output if idle - **idle_output_en**
|
||||
* Set the signal level on the RMT output if idle - **idle_level**
|
||||
:esp32s2: * Specify maximum number of transmissions in a loop - **loop_count**

Receive Mode
|

^^^^^^^^^^^^
|
||||
|
||||
In receive mode, set **rx_config** and the following members of :cpp:type:`rmt_rx_config_t`:
|
||||
|
||||
* Enable a filter on the input of the RMT receiver - **filter_en**
|
||||
* A threshold of the filter, set in the number of ticks - **filter_ticks_thresh**. Pulses shorter than this setting will be filtered out. Note, that the range of entered tick values is [0..255].
|
||||
* A pulse length threshold that will turn the RMT receiver idle, set in number of ticks - **idle_threshold**. The receiver will ignore pulses longer than this setting.
|
||||
:esp32s2: * Enable the RMT carrier demodulation - **carrier_rm**
|
||||
:esp32s2: * Frequency of the carrier in Hz - **carrier_freq_hz**
|
||||
:esp32s2: * Duty cycle of the carrier signal in percent (%) - **carrier_duty_percent**
|
||||
:esp32s2: * Level of the RMT input, where the carrier is modulated to - **carrier_level**
