Some questions about the infrared sending

[z43740979]

I use the example rmt _nec_tx_rx.
The waveform detected from the GPIO on the transmit side is the waveform before modulation instead of the the 38KHz pulse.
So the receive side can not Therefore, the receiver cannot parse the received signal.
Is the signal sent by the send function rmt_write_items in the SDK a modulated 38Khz pulse? Or we need to increase the modulation circuit.

You can set a modulation on a rmt channel using ``rmt_set_tx_carrier``.
