Lora with Industrial Shield ESP32 19R PLC?

Avatar
Ghazi Drira

the code examples shared on the official website with the code for the Arduino PLC or the PLC 14 are not executable. 

Pin reset? Pin  Chip Select?

Pourriez-vous nous fournir un exemple de code fonctionnel pour l'automatisme Industrial Shield ESP32 19R avec le module LoRa RN2483 (en langage C ou microPython) ?


#include

#include

#include

#include "HardwareSerialPicMkesp.h"


HardwareSerialPIC sériePIC = HardwareSerialPIC();

Adafruit_MCP23X17 mcp;


void setup() {

    // Débit en bauds pour le port série

    Série.begin(57600);

    retard (100);


    Serial.println("Initialiser mcp");

    mcp.begin_I2C();


    Serial.println(" Réinitialiser le module LoRa (actif LOW)");

    mcp.pinMode(3, SORTIE);

    retard (100);

    mcp.digitalWrite(3, FAIBLE);

    retard (100);

    mcp.digitalWrite(3, ÉLEVÉ);


    Serial.println("Démarrer le module LoRa");

    sériePIC.begin(120, 17);

Serial.println(serialPIC.available());

    // Vider le port

    while(serialPIC.available()) {

        Serial.print((char)serialPIC.read());

        retard(10);

    }

    Serial.println("okkkkkk");

}


boucle vide() {

    if (Série.disponible()) {

        octet rx = Serial.read();

        sériePIC.write(rx);

        

    }


    si (serialPIC.available()) {

        Serial.print((char)serialPIC.read());

    }

}

Here is a code for an ESP32 + LORA PLC, I hope you find it useful.

/*
 *  Board: ESP32 Dev Module
 *  
 * To set the frequency:
 * sys get ver  // Check that there is communication requesting the module firmware version
 * radio set freq 915000000	// United States
 * radio set freq 868000000	// Europa
 * radio set freq 433000000	// Asia
 * radio get freq		// Check that the correct frequency has been configured
 
 *  To receive:
 *  mac pause
 *  radio rx 0
 *
 *  To send:
 *  mac pause 
 *  radio tx ABC
 *
