RMT Transmit Example
This example shows how to configure and operate the remote control (RMT) peripheral to transmit a sample message in the Morse code.
Configuration (pin number, etc.) can be modified in the top of the main/rmt_tx_main.c
file.
To be able to see and hear the message output by the RMT, connect a LED and a speaker or an earphone (be careful - it may be loud) to the GPIO configured under RMT_TX_GPIO
define (default is GPIO 18).
Example connections:
330R LED
GPIO18 +----/\/\/\----+------|>|-----+ GND
