/*
|
|
* Example sketch for reporting on readings from the LD2410 using whatever settings are currently configured.
|
|
*
|
|
* This has been tested on the following platforms...
|
|
*
|
|
* On ESP32, connect the LD2410 to GPIO pins 32&33
|
|
* On ESP32S2, connect the LD2410 to GPIO pins 8&9
|
|
* On ESP32C3, connect the LD2410 to GPIO pins 4&5
|
|
* On Arduino Leonardo or other ATmega32u4 board connect the LD2410 to GPIO pins TX & RX hardware serial
|
|
*
|
|
* The serial configuration for other boards will vary and you'll need to assign them yourself
|
|
*
|
|
* There is no example for ESP8266 as it only has one usable UART and will not boot if the alternate UART pins are used for the radar.
|
|
*
|
|
* For this sketch and other examples to be useful the board needs to have two usable UARTs.
|
